Adventure Time/Tropes D to H
- Dance Party Ending: The ending of "Trouble in Lumpy Space".
- Dandere: Raggedy Princess. She spoke for the first time in the series to Finn in "Mortal Recoil" when she brought him his new backpack.
- Darker and Edgier: "City of Thieves" is this compared to the rest of season one. As is "What Have You Done?"
- "Ocean of Fear" is all about facing the physical embodiment of fear, which makes for a much darker episode. In addition, Pat McHale's quote at the end of the show gives one pause. This is also one of the few times we get serious evidence of Ooo's post-apocalyptic feel.
- The second season, especially the finale.
Princess Bubblegum: If you fail... he'll kill everyone.
- Season three seems to be heading this way as well... and even MORE so.
- "No One Can Hear You" is perhaps the worst one to date. A sadist deer, a brain-damaged Jake who went Cloudcuckoolander verging on Nightmare Fuel Station Attendant and kept Finn prisoner, the Candy People's fate, and the fact that the deer was killed by two cinderblocks to the brain and the body was flushed down the sewer system. Holy...crap.
- "Jake vs. Me-mow" features an assassin named Me-mow, a tiny cat who actually stabs a doorman to deliver a death threat to Wildberry Princess, and threatens to make Jake die quicker and quicker if he doesn't kill Wildberry Princess himself.
- The Ice King's origin in the episode "Holly Jolly Secrets Part II". He was once a human named Simon Petrikov who bought a mysterious crown from a merchant, when Simon wore the crown he began to hallucinate and eventually this drove his beloved fiancée Betty away. Over the period of several years his body began to transform, and his mind was slowly overcome by madness, resulting in him becoming the Ice King. It was probably the darkest back story in Adventure Time and on Cartoon Network.
- The fruit witch scene in "Dad's Dungeon", which happens to feature blood and bones. Specifically the blood and bones of anyone who eats one of the small apples, as those turn them into giant apples on the outside. Finn had a pretty good idea of what would happen if he ate the food, but was going to anyway due to feeling like everyone he cared about turned against him. Jake saves him by swiping the apple and forcing one of the three witches to bite it, causing her to transform and the other two to eat her.
- In the fifth and sixth episodes of the fourth season, Finn and Jake visit what is basically Hell. Except for the fact that people who die don't go there.
- Season three seems to be heading this way as well... and even MORE so.
- Dark and Troubled Past: In the episode "The Apple Thief", Jake says he knows the darker side of the Candy Kingdom. He used to be a criminal who stole purses and hawked stolen bicycles which could explain his actions in "City of Thieves".
- The Ice King.
- Darkest Hour: Finn goes through this for a short time in "Freak City"... Complete with awesome music!
- A Day in the Limelight: The Snow Golem, of all people!
- Dead Hand Shot: The title card for "The Jiggler". Of course, it has nothing to do with the episode.
- Deadly Prank: Played with in "Heat Signature"; Marceline's ghost friends actually wanted Finn and Jake to die. They and Marceline had tricked Finn and Jake into thinking they were vampires, whose powers include Flight. The extended prank culminated in the ghosts teaching them how to fly by knocking them off a tower (Marceline, drawing the line at actual harm, catches them). The ghosts did it because it would have been funny.
- Death by Gluttony: Clarence
- Demoted to Extra: Princess Bubblegum appears to have become this after "Hot to the Touch" where in "Hug Wolf" she merely gets a cameo where she is chasing a cat in the background and in "Princess Monster Wife" she doesn't even have any coherent lines.
- Denser and Wackier: "City of Thieves".
- Department of Redundancy Department: "If you fail, Marceline will be trapped in eternal sleep... FOREVER!"
- From "Tree Trunks":
"I want to carve my face on the moon... so the moon will look like my face!"
- From "Hitman":
Ice King: A leg cramp! In my leg!
- Depending on the Artist: Each episode (especially in the second season onward) has slightly different character appearances due to the art style of the storyboarders of that episode.
- Depending on the Writer: While Finn and Jake are always good, what kind of good they are seems to change. For example, compare "Business Time" and "Wizard", and notice how Jake acts. And for that matter, compare Finn in "Heat Signature" to Finn in "Morituri Te Salutamus".
- Deranged Animation
- Despair Event Horizon: Finn goes through this in "Incendium", to the point where he actually cries.
- Determinator: The Snow Golem from "Thank You"; it goes on a trek through an environment THAT ACTIVELY MELTS HIM to get the Fire Wolf Pup back to its family.
- Finn in "Another Way", so. Freaking. Much. Whenever he hits a road-block, he's convinced that he can still continue using his own methods. His own incredibly insane and Badass methods.
- Devil in Plain Sight: Ricardio.
- Didn't Think This Through: From "Her Parents"
Jake: Nah... That could never happen.
- Did You Just Punch Out Cthulhu?: In a misguided if courageous example, Jake almost kills Marceline, someone who effortlessly defeated Finn and him in an early episode, all while dressed as a strawberry and fighting his monumental fear of vampires to save his friend.
- Finn gets a turn when he defeats the Lord of Evil, Marceline's dad with two swords, a smiley face, bug milk, and some magic words, all while screaming to the top of his lungs.
- When Marceline's dad tried to suck out Gunther's soul, the little guy slapped him in the face.
- The legendary hero Billy casting down the Lich. Bonus points for it being said that he pummeled him into a tree where he imprisoned him in amber.
- Finn and Ice King manage to defeat the Lich again when he gets free. Not as utterly Badass as pummeling the guy into a tree, but still.
- Digital Piracy Is Evil: "Videomakers" is about Finn and Jake deciding to make their own movies for movie night, since (pre-apocalyptic) federal law prohibits unauthorized exhibitions of movies.
- Disproportionate Retribution: In "The Witch's Garden":
Finn: What did you do to him?!
- Flame Princess turns a few Fire Kingdom citizens into fire cats for whispering that she's normal.
- Distaff Counterpart: Fionna to Finn and Cake to Jake.
- Dissonant Serenity: Finn cheerfully decides to repress his memory of the real ghost in "The Creeps".
- Damsel in Distress: Finn and Jake's adventures frequently revolve around saving one or protecting one.
- Dude in Distress: Finn in three episodes:
- He got tied up and forced to run in a wheel in one episode. He was rescued by Jake.
- And then-- he got kidnapped by crystal guardians to be made into a crystal. He was, again, rescued by Jake.
- "Dungeon" has Finn and Jake both doomed until Princess Bubblegum suddenly flies in to save them... on a giant laser-shooting swan.
- Divide by Zero: Finn blowing a fourth-dimensional bubble, causing a black hole to form.
- Does This Remind You of Anything?:
Goblin criminal: Gimme those hot buns, lady!
- Doing It for the Art: In-universe in "What Was Missing".
Finn: Jake! You're back!
- Doorstopper: The UNABRIDGED version of Rainicorn history in "Paper Pete".
- Doppelganger Attack: Jake does this in "The Chamber of Frozen Blades".
- Does Not Like Shoes: Susan Strong.
- Also Princess Bubblegum is often barefoot, however her feet are often covered up by her long dress. Though with recent episodes she is shown wearing shoes more often.
- Flame Princess is always barefoot.
- Double Entendre:
- From "City of Thieves":
Finn: You made me steal. And you took my purity. You ruined me!
- From "It Came From the Nightosphere":
Marceline: You're like an ant to him.
- Same episode:
Finn: No one flicks me in the butt without my consent!!
- From "Gut Grinder":
Finn: Oh, Jake! You never turn into a monster when I ask you! It's always "Not now, Finn, I have a headache!"
- From "The Duke":
Finn: How can the dude be evil if he pets puppies, kisses babies, and lies with his wife?
BUFO: I will release elder Jeremy from his pledge [...] and you will take his place... for the rest of your natural life.
- Drama Bomb: Played straight and called out by Lumpy Space Princess in "It Came from the Nightosphere" when Marceline's dad hears Marceline's song.
- The BIGGEST drama bomb in Adventure Time history came with the Christmas special "Holly Jolly Secrets" when Finn and Jake view the Ice King's biggest secret, on video, when he himself is right there with them.
- Season three in general has been one great big drama bomb.
- Dramatic Wind: Happens whenever Sir Slicer shows up.
- Dramedy: Would you believe a cartoon like this has its dramatic moments? One example is Marceline's song in "It came from the Nightosphere". Starts out with her talking about her dad stealing her fries, then turns into heart-breaking ballad about how he neglected her.
- The show gets even more dramatic in "What Was Missing" when Marceline sings a deep song saying that she's annoyed that Princess Bubblegum treats her in an estranged manner, and then implies that she (Marceline) wants to make up with her in some way.
- Jake gets some of these moments in "No One Can Hear You," and there's also him nearly making Finn cry in "New Frontier."
- The Ice King has now been made into an extremely tragic figure, but even before then, he had sad scenes.
- Dreadful Musician: Finn when playing the viola, according to Jake.
- Driven to Suicide: Happens to Finn after believing that his father didn't think much of him in "Dad's Dungeon". Fortunately Jake manages to snap him out of it.
- Dual-Wielding: Finn uses two swords in "Slow Love" and "It Came from the Nightosphere".
- Dungeon Crawling: Finn, and eventually Jake, do this in "Dungeon".
- E=MC Hammer: Finn's first math problem in "Slumber Party Panic".
- Earn Your Happy Ending: "Ghost Princess" had a very sweet one, which required death and post-mortem trauma from a couple characters, but was rewarded with two lovers ascending to the next plane together.
- "Incendium" had a more subtle example. Jake tried to get Finn to move past the heartache he'd been suffering all season. The beginning of the episode had Finn hit an all time low, losing the will to do anything but curl in a ball and stare at a picture of Princess Bubblegum. Jake's lengthy Indy Ploy to snap Finn out of it, requiring a harrowing trip to the Fire Kingdom and a dangerous chase back, finally got Finn off his butt. Jake's efforts were rewarded with the words, "Dude. I think I have a crush!"
- Easter Egg: The ghosts' chanting in "Heat Signature" is a backmasked message to Pat McHale.
Ghosts: Farewell, Pat. Good luck in New York. Come back soon.
- Easy Amnesia: In "Death in Bloom", Jake gets amnesia from drinking the water in the River of Forgetfulness. Finn casually inflicts this on himself in "The Creeps", apparently something he regularly does when he experiences something disturbing.
- Happens again in "Return To the Nightosphere" where Finn and Jake find themselves in a prison somewhere in a nightmarish realm covered in bananas (It Makes Sense in Context) with no idea how they got there. The sequel, "Daddy's Little Monster", later reveals through Jake's cell phone that they were hanging out with Marceline in the Nightosphere, but an evil amulet given to her by her father who wanted her to continue family business caused her to turn into a chaotic evil Eldritch Abomination knocking out the duo and giving them amnesia.
- The Eeyore: The goblins.
- Eldritch Abomination: The Wall of Flesh from "Tree Trunks".
- Marceline's dad also qualifies.
- The Lich and Princess Bubblegum after he possesses her and regains his true power. It's so powerful it requires an Enemy Mine with Ice King to defeat it.
- The "Lub-glubs" from the episode "Beautopia" are most definitely this, only apparently inhabiting pool toys.
- In "Dad's Dungeon", the final monster that Finn and Jake fight.
- Anyone who happens to wear Marceline's dad's amulet becomes chaotic evil and turns into a horrific soul-sucking monster in his image, including Marceline and Finn.
- Eldritch Location: The crystal world and the Nightosphere.
- Elemental Rock-Paper-Scissors: Lampshaded in "Heat Signature," when Finn and Jake are being attacked by some ghostly friends of Marceline after a prank gone wrong.
Marceline: Finn, Jake... I'm so sorry I got you into this. I should've never pranked you so perfectly.
Jake: You shouldn't marry Finn. He pees his pants. Constantly. All the time.
- Emoticon: Beemo's screen shows a "D:" when his controller is stolen in "What Was Missing".
- Empathic Weapon: Billy's gauntlet.
- The End - or Is It?: In the last two seconds of "Jake vs. Me-Mow", Me-Mow is seen flying on a bluebird after it was believed she had fallen off a cliff.
- Enemy Mine: Finn and Jake teamed up with the Ice King to stop the Lich-possessed Princess Bubblegum after she went One-Winged Angel.
- He does this again in a short heralding in the third season, he seems to enjoy it, even though the duo bluntly told him to commit a Heroic Sacrifice in the process.
- Episode Title Card
- Eternal English: The businessmen's weird grammar in "Business Time" can be taken as an aversion of this trope.
"We love work for you!"
- Even Evil Has Standards: The Ice King will kidnap unwilling princesses left and right and try to make one of them his bride, but he loses interest in Princess Bubblegum when she's aged down to 13. He's creepy, but he's not THAT creepy.
- And yet, he writes fanfiction about the genderbent version of Finn falling in love with him...
- "Everybody Laughs" Ending: The ending to "When Wedding Bells Thaw", complete with an Iris Out.
- Also the ending to "Apple Thief".
- Everyone Calls Him "Barkeep": Most of the royalty in the show, excluding Marceline. Princess Bubblegum also might be an exception since Bubblegum is really her surname.
- Everything's Better with Bob: Bob Rainicorn.
- Everything's Better with Princesses: There are a lot of princesses in the land of Ooo. Princess Bubblegum, Hotdog Princess, Lumpy Space Princess, Muscle Princess, Slime Princess, and so on. Then there's Princess Princess Princess. Pen's official stance on the abundance of princesses is "WHY NOT. AMIRITE? LADIES? GUYS? RIGHT? AMIRITE?"
- Except for Dr. Princess. Princess is just her surname.
- Everything's Better with Sparkles: My god, that glorious HAIR!
- Everything's Better with Penguins: The Ice Kings penguins provide a nice touch of funny and cute.
- Everything's Worse with Bears: Billy FOUGHT A BEAR. A mountain-sized, flying bear. Just as great a feat as slaying an ocean or casting down the Lich.
- Everything Trying to Kill You: The Evil Forest.
- The Dungeon
- Evil Detecting Peppermint Butler: This was one of the first signs that Princess Bubblegum was possessed by the Lich.
- Evil Overlooker: The title card for "The Eyes" gives this vibe.
- Exactly What It Says on the Tin: No, not the title itself (Thought it would kind of fit). In "Mystery Train" Jake grabs a train schedule. It has "you got a schedule" written on it.
- Explaining Your Power to the Enemy: See Attack Its Weak Point, above.
- In "Jake Vs. Me-Mow", Me-Mow boasts that she has injected Jake with enough poison to kill a dog fifty times his size. Which prompts Jake to use his powers to grow his liver fifty-one times its normal size, curing the poison.
- Exposition: From "Videomakers":
Finn: ...And a thimble of milk for Shelby, the worm who lives in Jake's viola.
- Expository Theme Tune: Quoted above.
- Expy: According to Word of God, Fionna is partially based on Sailor Moon.
- Highlighted with the dress Fionna wears to the ball, it's almost Princess Serenity's.
- Finn's design partly comes from a character named Bueno, another one of Pen Ward's creations.
- Eye Beams: Tree Trunks.
- Eyedscreen: "Ricardio the Heart Guy", This trick shows up when Finn says that Ricardio is "up to something."
- Eye Scream: Peppermint Butler suffers this when he gets Princess Bubblegum's spicy potion in his eye in "Too Young".
- Faking the Dead: Finn in "What Have You Done?" to make Ice King wail and save the citizens of the Candy Kingdom.
- Finn, Jake, Beemo, LSP, and Cinnamon Bun do this in "Conquest of Cuteness" to make the Cute soldiers feel better about themselves. LSP exaggerates hers by pretending to fall in love, then fall out of love with one of the Cuties, and consequently have a fake heart attack... for laughs.
- Family-Unfriendly Death: In "No One Can Hear You", a deer's head and neck are crushed by two cinderblocks, and then his body gets flushed down a giant sewer pipe!
- Ghost Princess died after Clarence stabbed her. Clarence died after stuffing himself with so much soft cheese that he straight-up exploded.
- The third season is fond of this trope apparently. In "Dad's Dungeon", a fruit witch is eaten until nothing but her blood-covered bones is left. And that was almost Finn.
- Fan Disservice: Oh, Tree Trunks. You card.
"I'm the sexiest adventurer in the world!"
- Fan Fiction: In universe example. Adventure Time with Fionna and Cake was a fanfic written by the Ice King.
- Fan Service: Finn... popping his top?
- Fantastic Racism: The episode "Trouble In Lumpy Space" thoroughly establishes that there's a small bit of friction between lumpy and smooth.
- There is apparently also some tension between magic dogs and rainbow unicorns, especially in the wake of the dog/unicorn wars.
- Fish people!
- Fantasy Kitchen Sink: Ninjas, cyborg barbarians, Post Apocalyptic setting, knights, dragons, talking animals, wizards, etc.
- Fate Worse Than Death: You've gotta understand. That couch is really uncomfortable!
Finn: Can we just get back to the brain-eating, or whatever?
- Dying in the Fight King's arena results in you being trapped there as his ghost gladiators forever. Finn managed to kill the Fight King, setting the ghosts free.
- From "To Cut a Woman's Hair":
"Well, maybe you should help me get some princess hair, so maybe your friend won't be sucked into my bottomless bottom!"
- The fate of Princess Bubblegum and the Candy People in the episode "No One Can Hear You".
- Fearful Symmetry: The Crystal Guardian of the Crystal Gem Apple. Unlike some examples through, it's not an actual clone, but an imitator made out of hard, sharp crystal. When you punch its punch, you're the one getting hurt, not it.
- Fee Fi Faux Pas: Finn makes one when he yells at the top of his lungs at a candy party in "Ricardio the Heart Guy".
Finn: I'M NOT JEALOUS. I'M WEIRD!!!
- Female Feline, Male Mutt: Jake is a male dog and his Distaff Counterpart, Cake, is a female cat.
- Feud Episode: "Videomakers". Finn and Jake argue over whether to make an Action Adventure or a Romantic Comedy for their movie club.
- Feudal Future
- Fighting Your Friend: The modus operandi of the Fight King is to lure fighters to his colosseum in pairs and eventually pit them against each other. The ghosts of previous challengers moan for the forgiveness of their friends as they fight. Finn uses the Fight King's love of this to trick him into giving him his Soul Jar, which Finn promptly smashes.
- The Final Temptation: The Ice King pulls this in "What is Life?" To try to get NEPTR to become his son, Ice King takes the robot to his Imagination Zone and offers him a life of capturing (and "mating with") princesses.
- Find the Cure: "Trouble in Lumpy Space". Jake gets "the lumps" when Lumpy Space Princess accidentally bites him, so Finn and they must go to lumpy space and find a cure before sunset.
- Finger Gun: Jake does this in "The Duke".
- Fireball Eyeballs: Marceline in "Heat Signature".
- Fire-Breathing Weapon: Finn and Jake use one each at the beginning of "Business Time".
- Fisher Kingdom: The City of Thieves is an interesting take on it, as unlike other Fisher Kingdoms, this one just has so many acts of thievery that you're just gonna wind up stealing something back without any actual mental or physical changes.
- Five-Man Band: Finn, Jake, Marceline, Bubblegum, and Beemo form one in 'What Was Missing'.
- Flat What: Marceline lets one go when Finn says he wants to get in her dad's pants.
- Flatline: Happens for a short time when Princess Bubblegum is in the hospital in "Mortal Recoil", but then her body mass stabilizes itself.
- Flipping the Table: In "What Have You Done?", both the title card and the episode proper, and both by Princess Bubblegum.
- Foil: Ice King and Scorcher. The Scorcher's fire powers and competency contrasts with Ice King's ice powers and incompetency.
- Foot Focus: The majority of the episode "Freak City" has Finn turned into a giant foot
- "Marceline's Closet" contains a close-up of Marceline taking her socks off before her shower.
- Foreshadowing: In the Ice King's genderbent fanfic "Fiona and Cake", when Cake joking puts on the Ice Queen's crown Fiona immediately smacks it away, yelling, "No! You might catch her crazy!". In "Holly Jolly Secrets Part II", it is revealed that the Ice King's crown is what caused his insanity.
- In "The Eyes", where a horse spies Finn and Jake all night, at the beginning Finn remembers all the adventures they have in that week, one of them is rescuing yet another princess from the Ice King, and he screaming: I only want to be happy. The end of the episode shows The Ice King disguised as the horse spying Finn and Jake to learn how to be happy.
- For the Funnyz:
- Finn's entire adventure in "What Is Life?" is for the goal of seeing Jake get pied in the face.
- Fountain of Youth: Present in the Season 2 Finale. Princess Bubblegum ends up being shattered to pieces in order to defeat the Lich who possessed her body. Not all of her pieces could be located, causing her to revert to a 13 year old girl, who looks even younger.
- Four-Fingered Hands: Varies. Even the character sheets for storyboard artists explicitly state that the characters can have either 3, 4 or 5 fingers, depending on what is needed or looks good.
- Billy, the legendary hero, has six fingers on both hands, at all times.
- Frankenstein's Monster: Princess Monster Wife, built by the Ice King by taking various random body parts from all of the other princesses.
- Free-Fall Fight: There's one at the beginning of "His Hero". Finn & Jake vs Swamp Giant.
- Freeze-Frame Bonus:
- In every episode a waving snail appears for at least one scene. They actually forgot to put it in "Trouble in Lumpy Space", but added it for reruns. In the second season finale, this takes a dark turn when it turns out that Lich performed a Body Surf to take it over as his new host.
- A horse in a party hat, a grave robber, a taco, yo whadup, a nerd
- One scene in "What Have You Done?" has a book with a string of numbers on it: 5318008. Converted to "calculator" font and turned upside-down, this reads "boobies".
- Can you spot the NES?
- "AT43VR". Adventure Time forever!
- The heart monitor at the beginning of the episode "Mortal Recoil" displays the digits "3.1415 92653 58979", the first 15 digits of pi.
- In "Apple Thief", when Tree Trunks is held up to the mirror, the message "·- - WUZ HERE" can be seen to the side. In Morse code, "·- -" means "A. T." Guess what "A. T." means. No, not "Apple Thief"!
- In "Beautopia", we see a Lub Glub shaking a skull. Look carefully at this skull; the skull is wearing a hat with bunny ears. Who else wears/wore a hat with bunny ears?
- There is also a cat skeleton suspiciously similar to Cake on the pile of skulls underneath.
- In "Marceline's Closet", we get a barrage of bonuses.
- If one looks at the title card, you'll see that Marceline has no reflection in the mirror.
- As Marceline enters her room, we can see a copy of Madonna and Child.
- Marceline's journal has the word GUNTER on it.
- Her trophies on a wall include a head and arm that look like that could belong to the Pale Man from Pan's Labyrinth.
- In Hunson's house, there is a portrait of him golfing with Peppermint Butler.
- Frickin' Laser Beams: Princess Bubblegum has a flying swan that shoots lasers.
- Fridge Horror: Done in-universe in three episodes:
- The end of "Business Time," when Finn realizes he can't simply bid begone his gargantuan gut like Jake did.
- The end of "Mystery Train", where Jake says that if the gelatin wasn't there at the end of the track, Finn and him would've plunged to their deaths. Finn then stares at the tracks, looking at what might have happened.
- In "Morituri Te Salutamus" Finn explains that if Jake had messed up his plan, Finn might've really chopped his head off. After a moment of silence, they laugh it off.
- The Full Name Adventures: The old title--Adventure Time with Finn & Jake.
- Funny Background Event: "MY TUMMY'S BREATHING FIRE!"
- Fur Bikini: Jungle Princess.
- Gag Lips: The result of LSP's formula in "From Bad To Worse".
- Gainax Ending: "Tree Trunks" ends with the titular character taking a bite from the fruit they've been pursuing all episode. She explodes. Then we see her running, laughing, through crystal.
- That one got a Mind Screwdriver.
- Also "Evicted". After a whole episode of dealing with Marceline taking over Finn and Jake's house, she gives it back... and they return to find a giant worm that blasts them with a ray of some sort and asks them to hug it.
- The end of "Power Animal" when Jake suddenly says "Let's go eat Cinnamon Bun!"
- Adventure Time evidently loves this trope. There was another one in "Chamber of Frozen Blades" when Gunter, one of the Ice King's penguins that he took to the hospital, lays an egg that hatches... into a floating pink kitten. Then the Ice King says, "Gunter, why didn't you tell me? Oh-ho-ho, Gunter-" as he is interrupted by Finn and Jake both kicking him.
- Another example is at the end of "Her Parents" when Finn and Jake taste "Soy People," which is said to taste exactly like humans... of which Finn is the last because Rainicorns eat them. Not at all helped by Jake actually saying, "Finn, you taste delicious!"
- Aaaand yet another at the end of "Mystery Train" when the train falls off an open cliff and lands on a gelatin person. Jake says that this wasn't planned, and he was the one who arranged the train ride for Finn. The ending seems to suggest that Jake knew this the whole time and either he or the designer of the train tracks was planning to commit a mass murder-suicide.
- The most intense one yet comes in the form of "Holly Jolly Secrets" whose ending should really speak for itself. It involves a deeply disturbing and realistic portrayal of the Ice King losing his mind.
- "Hug Wolf"
- GASP: Finn and Jake's reaction to the Glasses of Nerdicon.
- Gender Blender Name: Tiffany.
- Also Gary... the Mermaid Queen.
- Who gets Bonus Points for also not looking anything like a mermaid.
- Also Gary... the Mermaid Queen.
- Gender Flip: Exaggerated with "Adventure Time with Fionna & Cake". Everyone is gender-flipped. And we mean everyone--even the background characters (e.g., Mr. Cupcake is Ms. Cupcake, the Gumdrop Lasses are Gumdrop Lads, hell, even the staffers). They even went Up to Eleven and changed the Creator Cameo of Adam Muto to Rebecca Sugar in the opening sequence.
- Generic Cuteness: Princess Bubblegum
- Genre Savvy: When Finn and Jake journey to the land of the dead, Finn is cautious about drinking from the river.
Talking Skull: Yesss... drink the water.
- Also in "Mystery Train", Finn concludes that Colonel Candycorn cannot be the murderer because in murder mysteries, the culprit is not usually the one suspected first.
- In "Morituri Te Salutamus", Finn and Jake knew before even entering the arena that the doors would magically shut and they would have to fight a multitude of gladiators. Finn wanted to go in anyway being the Blood Knight that he is. Finn was also Genre Savvy enough to invoke Unspoken Plan Guarantee and know that the big, magical sword the Fight King had was the Fight King's Soul Jar.
- In "Dad's Dungeon", Finn and Jake knew that the flower path was a trap, but they took it anyway because the other path had a really gross dude in it. It's implied that Finn also knew that the apple would kill him, but he was Driven to Suicide at the time.
- Geometric Magic: The incantation for summoning Marceline's dad requires a circle. With a smiley face on it. Also works for banishing him.
- Get Out!: In "Mortal Recoil", Finn gets so angry at Ice King for accidentally dropping Princess Bubblegum into a well of toxins that he simply tells him, "Just get OUT OF HERE!!"
- Getting Crap Past the Radar: Has its own page.
- Ghost Amnesia: The deceased in Ooo apparently get this, as seen in "Ghost Princess".
- Giant Foot of Stomping: Jake does this to Ash.
- Giant Spider: The episode "Web Weirdos" features these.
- Glad I Thought of It: From "Wizard":
Finn: You don't need to quit your job.
- A Glitch in the Matrix: Happens in "Adventure Time with Fionna and Cake".
Fionna: But there is one guy I'd do anything to date... THE ICE KING!
- Go Into the Light: The concept behind "Ghost Princess" was that said character could not move on because she needed to know how she died.
- Golden Mean Fallacy: Instead of choosing to wish for the Ancient Psychic Tandem War Elephant and letting Jake die, and wishing for Jake to heal while sacrificing the Ancient Psychic Tandem War Elephant, Finn uses the elephant to wish Jake back to full health and bring the Hot Dog Knights back to life.
- Golem: Jake defeats one in "The Limit".
- Gone Horribly Right: In "Incendium", Jake's goal was to find Finn a new love. When he showed Flame Princess "Finn", he made her think that he didn't like her, which sent her on a rampage. She chased Jake back to the tree fort, where she met the real Finn, and slapped him for being screwy with her; Finn somehow developed a crush on her. So all in all, Jake succeeded in getting Finn a crush... on possibly the most insane, deadly, and evil princess in Ooo.
- Further escalates in "Hot To The Touch", when it becomes clear that Finn is truly smitten with her. His Adorkable attempts at wooing her leads to the Goblin Kingdom nearly being burnt down to the ground.
- Gone Horribly Wrong: The Decorpsinator Serum.
- The creation of Lemongrab.
- Gosh Dang It to Heck: By necessity. However, they do manage to sneak some Parenthetical Swearing in:
Finn: You just like to say poop that jacks with my brain.
- Grandma, What Massive Hotness You Have!: Ice Queen (Ice King's female counterpart).
- Gratuitous German: In "What Have You Done?" by Princess Bubblegum. She says "Ich bin so glücklich, ich könnte, ich könnte..." meaning "I'm so happy I could, I could...".
- Great Big Book of Everything: The Enchiridion.
- Great Offscreen War: Both the Mushroom War and the war between dogs and rainicorns qualify.
- Green Hill Zone: The "Grassland" region of the Land of Ooo.
- The Grim Reaper: Just like all the other mythical creatures in this show, he's a bit different than what you'd expect. He's a zen gardener.
- Groin Attack: Apparently, excellence in this is a heroic attribute. Finn does this one a good number of occasions. One time he even did it to a giant...after being transformed into a giant foot.
Two-Headed Giant: OUR CROTCH! OUR EEEEVIL CROTCH!
- Marceline gives Ash a Groin Attack after he basically tells her to go to the kitchen and make him a sandwich. "Also, pickles."
- Gross-Out Show: Early seasons of the show had elements of this, but later episodes.. not so much.
- Grows on Trees: In "The Witch's Garden" the eponymous witch has a garden full of donut bushes (and she plants a cupcake plant in the end). In "The Pods", magic bean sprouts give: adorable pigs, sparkly wands and an endless supply of icecream. The pigs are pure evil, though.
- Ha Ha Ha No:
Peppermint Butler: It's just a prank, man, for laughs!
- Hair Flip: A rather impressive one in "To Cut a Woman's Hair" by Finn.
- Hair of Gold: Finn. Also Compressed Rapunzel Hair, at least until it's cut.
- Susan Strong also (seemingly) has blonde hair.
- Hair Wings: The Ice King uses his beard like a pair of small wings to fly. He of course loses this ability when he shaves it.
- Half-Dressed Cartoon Animal: Zig Zagged with Jake: He is in fact wearing a pair of translucent, form-fitting pants spun from spiderwebs by pixies.
- Halloween Episode: "The Creeps" and "From Bad To Worse".
- Hand Blast: Finn gains this ability after equipping Billy's gauntlet.
- Hand Seals: Fridjitzu requires the use of these.
- Hand Wave: Finn is supposed to be the only human in the show aside from Susan Strong, possibly. However there is a recurring background character named "Phil" who is based on a former worker on the show, Phil Rynda, and he looks incredibly human. When someone on the crew is asked what the hell Phil is, they usually say something along the lines of, "He's a Phil."

- He Who Fights Monsters: In "City of Thieves" this happens to Finn, resulting in a rather Darker and Edgier version of himself. Complete with a Badass Cape.
- Heartbeat Soundtrack: The background music for "Ricardio the Heart Guy" at one point.
- The Heartless: Fear Feaster, who is the embodiment of Finn's fear of the ocean.
- Heel Face Turn: Marceline's dad in "Daddy's Little Monster"... kinda. It's always "kinda" with this show.
- Hellfire: The Nightosphere has this. And the Fire Kingdom. Princess Bubblegum summoned Hellfire when she was possessed by the Lich in "Mortal Recoil".
- "Hell Yes!" Moment: In "Dad's Dungeon", it looks like Finn's going to die believing that both Jake and Joshua think he's stupid and can't do anything right. Break out the baddest song ever laid down in the show's history and the demonblood sword.
- Heroes Prefer Swords
- Heroic BSOD: Jake goes pacifist in "Crystals Have Power" when he hurts Finn while roughhousing, which makes him recall a time where he did the same with his brother, and his father's response was "You're gonna hurt everybody!" Eventually he has a vision of his father, who says "I meant you'll beat up everyone evil! Let me finish next time!" Jake responds, "Oh, well, I'm over it then!"
- Finn goes through a short one in "Susan Strong".
- Finn has another in "Dad's Dungeon" arguably the worst in the series as at one point he was going to eat an apple that would leave him in a position to get eaten by witches, fully aware of what would probably happen to him.
- The next episode, if you can believe it, has an even worse one. When Princess Bubblegum rejects him again, he just lies on the floor staring at framed pictures of her, and doesn't even respond when his house catches on fire.
- Heroic Build: Younger Billy.
- Heroic Sacrifice: Stormo, a Candy Spinx created from Finn's DNA, sacrifices himself by trapping himself forever in a duel with the evil, power mad Goliad.
- He's Back: At the end of "His Hero", Billy decides to return to fighting evil after Finn and Jake convince him it still works by showing him an old lady they just saved by beating up a monster.

- Hoist by His Own Petard: The Ice King.
- The two-headed giant gets one too.
- Donny as well.

- Hulking Out: Finn, when something happens to Jake. Then he's talked down by Jake and calms down.
- Humanity Ensues: At least three different processes are shown to give human attributes to the otherwise inanimate objects, cyclops tears, power of the ice crown and lightning from "ordinary" storms. Usually this will put a human-like face on the object. It is unclear how much this has to do with the general Moe Anthropomorphism of the series.
- Humanity's Wake
- Humanoid Abomination: Marceline's dad in various ways. Do not threaten him while he's sucking souls.
- Scorcher might count, having vast inexplicable powers and being completely mute.
- The Freak Deer counts in a way. A lot of the horror in its portrayal is that it's simply a completely silent, completely sinister humanoid deer, with all the alien otherness that implies.
- Human Popsicle: The Businessmen from "Business Time".
- The Hyena: The monster at the end of "Dad's Dungeon".
- Hypercompetent Sidekick: The Businessmen.
- Hypnotize the Princess: Ice King does this in "When Wedding Bells Thaw" to get a princess to marry him.
- Hypocritical Humor: In "Trouble In Lumpy Space", just before Jake goes full Lumpy, he says he'll never turn his back on Finn. Then he goes full Lumpy, and the other Lumpies call him over, and he says he'll be right over, as soon as he turns his back on Finn. And he literally does.
