Incredible Shrinking Man



Bees and moths whirr above you like helicopters. Flowers and blades of grass loom over you. Familiar household objects are like huge, immovable obstacles. Your fellow human beings blot out the sky with their immense, towering girth. Sound like a bad case of the Mondays? Think again: you've been shrunk!

The plots of Shrinking Man stories tend to involve hapless victims of Applied Phlebotinum suddenly becoming one finger tall (Magic Pants included), struggling to navigate a formerly friendly environment (such as a house or yard) and spending the rest of the episode trying not to get killed or eaten while attracting the notice of normal-sized folks who might be able to change them back to normal. (Don't expect the message to get across immediately.)

A subset of Shapeshifting. Often times this is how the human protagonists are introduced to (and/or imprisoned in) the Mouse World.

Considered somewhat hokey to do in live-action nowadays, even in Sci Fi, owing to the Square Cube Law. In cartoons, however, you can get away with it.

If the characters are shrunk down far enough, they could embark on a Fantastic Voyage Plot.

Depending on how the shrinking works, they may or may not get their clothes to shrink with them--resulting in Empty Piles of Clothing or something similar.

Contrast with Attack of the 50 Foot Whatever. See also Shrink Ray.

Anime and Manga

 * Happens to Narancia in Part 5 of Jojo's Bizarre Adventure when he's attacked by an enemy with the ability to shrink his victims by stabbing them with his dagger.
 * Happens in the Cardcaptor Sakura TV episode where Sakura is shrunk by the Little card.
 * Hiroshi from Hell Teacher Nube wakes up one day to find himself no larger than a mouse. Of course, the reality of the situation is stranger still.
 * Himeko Nonohara gains the ability to do both this and Attack of the 50 Foot Whatever later on. Of course, since she doesn't want to give away her secret, she uses the latter a lot less than the former.
 * Happens only in the manga version of Busou Renkin, when Tokiko is hit multiple times by Madoka's Bubble Cage.
 * Also happens in Ghost Sweeper Mikami, when the eponymous Action Girl is hit by a dart from a spirit and in few hours she's shrunk to the size of a Barbie doll. She and her assistants must find the culprit and exorcise him, lest she will keep shrinking and disappear.
 * Happens in one episode in the anime adaptation of Kochikame when the main character Ryotsu was shrunk by the wizard from Heaven. He goes through mishaps in the police box and later helped taking out criminals holding up hostages.
 * Happens to the 5 main girls in Yes Pretty Cure 5 GoGo! when one of the villains gives them a fake version of the Rose Pact that shrinks them.
 * One episode of To Love Ru has Rito at the receiving end of Lala's shrinking machine. Considering this is To Love-Ru, you can expect what comes from Rito's new perspective.
 * In one episode of the original Dragonball, Bulma develops an invention that can shrink anybody. Master Roshi decides to use it to watch Bulma go to the bathroom.

Comic Books

 * DC Superhero The Atom had this as his power; some plots involved him or other characters shrinking and then having the size controls taken away/break.
 * And of course, there was the appearance of the Atom at the end of Identity Crisis,.
 * In The Dark Knight Strikes Again, Batman rescues him from a deserted island in a strange universe full of monsters.
 * The Atom has also lampshaded some of the oddities of his powers. When questioned about how people can breathe when they're barely the size of a cell, he admits that he has no idea how and he just goes with it.
 * Bumblebee from the Teen Titans and Doom Patrol was accidently reduced to the size of a small toy. Unlike most shrinking superheroes, she has yet to find a way to regain her original size.
 * In the Superman/Superboy/Supergirl DC 'verse, an entire CITY (Kandor) was shrunk to microscopic size so as to preserve it when Krypton exploded. Superman kept it in what appeared to be a five gallon water bottle. Superman and others (notably Jimmy Olsen) would visit after being shrunk by various means but, apparently, any inhabitant who escaped the bottle automatically grew to "normal" size.
 * Incorrect. While Kandorians would gain superpowers upon leaving the bottle's artificial Kryptonian environment, they wouldn't expand unless some kind of Applied Phlebotinum was used.
 * In fact, many comic book characters have shrinking (or size-changing in general) as their primary superpower (i.e. Ant-Man, the Wasp...)
 * This happens to Donald Duck, Scrooge and the nephews (along with Scrooge's whole money bin) in several different comic books by Carl Barks and Don Rosa. One of these was also "adapted" into a Duck Tales episode, except that the episode had almost nothing to do with the story aside from the premise of the characters getting shrunk.
 * One quasi-educational story from the early '60s had Donald take his nephews (through an uncannily prescient virtual-reality device) on a trip through the mundane everyday world while shrunk increasingly smaller to encounter phenomena more fantastic than any make-believe reality the nephews could think of.
 * Happened to Bart in an early issue of The Simpsons comic book.
 * Almost every incarnation of the Teenage Mutant Ninja Turtles has a story of this type. The first cartoon (and subsequently, the Archie comic book based on it) did this during the "Eye of Sarnath" arc in an episode called "The Incredible Shrinking Turtles". The Mirage comic book has this as Donatello's current status quo (as of May 2009). The second cartoon had the episode "The Incredible Shrinking Serling", where time travel (don't ask) makes him the size of an action figure.
 * The Fantastic Four found themselves in a variant situation when they are captured by Doctor Doom and placed in a machine where their consciousnesses were transferred into miniature duplicates of themselves in a tiny simulation of a town called Liddleville. Eventually, they break out, manage to defeat Doom in their mini-versions and restore their consciousnesses to their real bodies.
 * In the Marvel Universe in general, anyone who shrinks below a certain limit (apparantly somewhere between cellular size and molecular size) shifts into a "microverse" - the theory is that a shrinking person is actually displacng their mass extradimensionally, and when 99.99999999999999% is over there, the rest (and consciousness) follows. Among the notable inhabitants of microverses are Psycho Man, Jarella (a lover of The Hulk for a while), and the (now out of continuity) Micronauts.
 * Colossal Boy has this power in the 2004 relaunch of Legion of Super-Heroes. So why's he called Colossal Boy? Because he's from a race of giants, and has the power to "shrink" down to six feet tall. He insists on being called "Micro-Lad."
 * More traditionally, Legion regular Shrinking Violet, who comes from the planet of Imsk where everyone has shrinking powers.
 * The graphic novel In the Small features this happening to every human on Earth due to a mysterious blue flash. Shrunken, terrorized by animals and unable to use most technology, they need to rebuild everything in miniature.

Fan Fiction

 * In Huge Success, Tony decided to look at Dr. Pym's pym particles without permission and ended up being 6 inches tall.
 * Some form of shrinking happens in many of GirlX2's stories, often due to "Lilliputian Syndrome."
 * In With Strings Attached, the four get shrunk on their quest for the second piece of the Vasyn, though George fixes himself as soon as he has a lot of room to do so.
 * Actually, all of the humans in the chapter have been shrunk. The four manage to find a gun that will unshrink everyone.

Film

 * The most famous film examples are The Incredible Shrinking Man with Grant Williams and its Distaff Counterpart with Lily Tomlin.
 * It should be pointed out that the Square Cube Law may have been somewhat averted in this particular movie because Scott Carey very slowly shrinks, thus giving his body a chance to adapt to his changing size.
 * Both films were based on the novel by Richard Matheson, who also wrote I Am Legend and scripted the two Kolchak TV movies.
 * As noted in Stephen King's Danse Macabre, Richard Matheson originally made the eponymous man shrink a constant rate of 1/7th of an inch per day rather than by a given proportion, resulting in the Fridge Logic of what happens when he gets to that height.
 * The Lily Tomlin vehicle The Incredible Shrinking Woman made her decreasing size, caused by exposure to too many household cleansers, food additives, and hygiene products, a parable about out-of-control consumerism.
 * This was the basis for the plot of the live-action movie Honey I Shrunk the Kids, along with its sequel, Honey, We Shrunk Ourselves and the TV series that followed, also called Honey, I Shrunk the Kids.
 * In the Beatles movie Help, a character uses a special injection to shrink Ringo's finger in order to remove a sacrificial ring naming him an offering to a Hindi god, but misses and hits Paul in the leg, whereupon the scene cuts away to a card reading "The Exciting Adventures of Paul on the Floor".
 * In Dot And Keeto, Dot goes to eat the root that lets her talk to animals so she can apologize to some ants her brother was tormenting, but she accidentally eats the root next to it, which makes her shrink down to the size of a bug (and able to talk to them). After trying to get the attention of her brother and mother, she goes on an adventure among the bugs until her friend Kangaroo shrinks down, too, and brings her some of the root that will make her the proper size again.
 * "Fantastic Voyage" in which a submersible is shrunk to microscopic size to be injected into a comatose spy to laser away the clots that are killing him. This has been pointed out, more than once, leads to a stupid conclusion where the people abandon the ship and swim to safety, being extracted from the tear ducts before they return to normal size automatically. No mention is ever made of the sub growing to normal size and exploding the patient.
 * "Phantom Planet" where an astronaut lands on a tiny planetoid and, as soon as he breathes their air, shrinks to six inches tall (without his clothing). He later grows back to normal by breathing the air in his spacesuit tank. On MST3K they riffed "So people are just balloons?"

Literature

 * Happens twice in Animorphs. Once, a tiny alien race called the Helmacrons shrinks some of the Animorphs. The second time, the Helmacrons enter Marco's body, so the Animorphs have to shrink themselves in order to enter Marco's body and stop the Helmacrons from killing Marco.
 * The Incredible Adventures of Karik and Valya has two kids drinking some liquid and shrinking to insect size, then being whisked into nature by a dragonfly. Needless to say, the whole thing is very dangerous.
 * The British SF novel Cold War in a Country Garden.
 * There are the Gnomes of Discworld that are small compared to the humans but none of the setbacks. Sure they are small. But in that compressed form lies all the strength of a human in a miniaturized state. They can buy more food with their money (since they eat proportionally less) do the same amount of work and kick ass in squared amounts (as in they can hit with the equivalent force of a human but focused into the small point that the gnomes hit you at).
 * Shrinking is one of the less bizarre experiences Alice has in Wonderland.
 * Used in one of the Danny Dunn children's scifi adventures.
 * Two books in the Eerie Indiana series use this. The Incredible Shrinking Stanley, in which Stanley gets splashed with special soap from the Eerie laundry mat and starts shrinking, and The Dollhouse That Time Forgot where Marshall, after exploring a house that looks suspiciously like the dollhouse his sister just bought, finds himself getting smaller and smaller. The latter overlaps with The Doll Episode.
 * The Shrinking Man by Richard Matheson, on which the movie The Incredible Shrinking Man was based (almost all modern editions of the novel even add the "Incredible" part to the book's title, as the movie is more famous).

Live Action TV

 * Happens in Power Rangers ZEO ("A Small Problem") and Power Rangers Turbo ("Honey I Shrunk The Rangers").
 * Sabrina the Teenage Witch has one of her "magic diseases" where her guilt causes her to shrink.
 * Family Matters did this once, too.
 * In one episode of The Greatest American Hero, Ralph gets another copy of the suit's manual from the original aliens - but shrinks himself while experimenting, gets scared by an ant, panics and goes back to normal size, leaving the manual shrunk... I guess they also gave him an Idiot Ball to go with the replacement manual.
 * This was the premise of Dr. Shrinker.
 * In Doctor Who, a specific component of the TARDIS can change the size of things, and presumably relates to how a TARDIS can be bigger on the inside.
 * The early serial "Planet of the Giants" featured the first Doctor and companions trying to stay alive in a typical suburban home after a TARDIS malfunction reduced them to the size of bugs.
 * The First Doctor permanently crippled the TARDIS of the Meddling Monk by removing the "dimensional control" so the other Time Lord couldn't get back into his (brand new, more advanced) TARDIS; afterwards, the console room was too small for him to fit inside.
 * In The Invisible Enemy, the Fourth Doctor temporarily removed the "relative dimensional stabilizer" from his TARDIS to shrink clones of Leela and himself so they could be injected them into the doctor's brain to fight a virus (in an homage to the Incredible Voyage).
 * Later, another rogue Time Lord weaponized one in The Armageddon Factor (but wound up shrinking himself and the Doctor instead of the enemy).
 * The Master similarly uses a "Tissue Compression Eliminator" weapon which kills people by shrinking them, possibly the same technology but without the normally associated life support mechanisms allowing subjects to still breathe and such.
 * In Planet of Fire, they meet a minaturised Master who had an accident while working on his TCE.
 * Some similar non-Gallifreyan technologies showed up occasionally.
 * In "Carnival of Monsters" the Third Doctor accidentally landed the TARDIS inside a "compression field", where the people on the outside were giants in comparison. Anything removed from the compression field returned to normal size within a few seconds. (The first thing so removed was the TARDIS, because it was interfering with the compression field. A giant hand reached in and picked it up.)
 * In "The Pirate Planet", the Fourth Doctor encountered a bad guy who kept the shrunken remains of planets he'd destroyed as trophies.
 * Land of the Giants was a variation on this trope; while the main characters didn't shrink, they found themselves In a World of 40-foot people, so the effect was the same.
 * Farscape "I Shrink Therefore I Am". The crew are shrunk by bounty hunters to make them easier to transport and control. Sikozu immediately starts listing all the reasons why this is impossible (their brains should be too simple to function, and they shouldn't be able to breathe normal-sized air molecules) until Rygel tells her to just shut up and accept that the impossible has happened. The episode ends with a fight between Crichton and the Villain of the Week, with each trying to shrink the other and resize themselves. Needless to say, someone ends up getting squashed nastily.
 * Deep Space Nine episode "One Little Ship": A runabout is sent to study a Negative Space Wedgie whose shrinking effect is already known (the fact that the explorers will be shrunk is a matter of great amusement to those staying behind). Unfortunately the Defiant is captured by Jem'Hadar and the now miniscule explorers must help the crew take back the ship. One scene has Bashir and O'Brien having to exit the runabout to alter a circuit -- because they can't breathe the full-sized air molecules outside, they beam a bubble of the runabout's air inside the circuit's casing. The episode ends with Odo and Quark pulling a rare practical joke on Bashir and O'Brien, by pretending they haven't "quite" returned to full size.
 * On Misfits of Science, seven-foot-tall Dr. Elvin Lincoln had been working on a treatment that would make him shorter; he overdid it a bit and wound up with the ability to make himself six inches tall at will.
 * "The Mighty Mites" segment of Owl TV revolved around a group of kids who shrink themselves at will to study insects and other small creatures.
 * The first half of the two-part Mork and Mindy episode "Mork In Wonderland" centers on Mork shrinking after taking a cold capsule (the explanation is that the capsule is supposed to shrink the nasal membranes in humans, but Orkans are entirely membrane).
 * In Lois and Clark, Clark got shrunk to 6 inches tall. Thankfully, he still has all of his powers.
 * In the Charmed episode Size Matters, the Charmed Ones get shrunk by a demon with a shrink wand.
 * Sesame Street had a two-part story in which Big Bird was shrunk to about the size of a Twiddlebug.
 * In the Wild Wild West episode "the Night of the Raven", Dr. Loveless shrinks James West and a Native American princess.

Tabletop Games

 * One memorable scenario from the early days of Dungeon magazine involved the player characters being shrunk down to the size of gaming miniatures by a malfunctioning magical orb. Unusual in that, aside from the usual small animals posing a deadly threat, many previous groups of travelers had already fallen prey to this effect, forming themselves into Wacky Wayside Tribes that feud over the resources of a small garden.

Theme Parks

 * This is the basis for several attractions at Disney Theme Parks. A few include It's a Bug's Land, a play area based on A Bugs Life, another play area based on Honey I Shrunk the Kids and Honey I Shrunk the Audience, and the long gone Adventure Through Inner Space.

Video Games

 * This happened in Snowboard Kids 2. The main characters were shrunk down, turning Wendy's house into a snowboard track.
 * The Legend of Zelda: The Minish Cap uses this as a gameplay mechanic.
 * This is the entire story of Mario Party DS.
 * Ratchet and Clank Size Matters centers around a shrink ray.
 * Appears in a level in Okami where the eponymous wolf is shrunk down by magic to the size of her companion, Issun, and has to dodge such mundane dangers as spiders and Japanese housewives with brooms.
 * This happens in a scene to the heroes of both Breath of Fire I and Breath of Fire II.
 * This also happens to the heroes in a Shining Force II scene.
 * The 'Mini' spell and debuff in most Final Fantasy installments, which induces a status where all physical attacks are reduced to Scratch Damage and defense is lowered.
 * Minimize in the Pokémon games.
 * The Mini Mushroom in the New Super Mario Bros games shrinks Mario and co. to the size of a mouse. This allows them to fit in very small gaps and run on water, but one hit will kill them.
 * It also cuts their mass (because the Mario games already laugh in the face of physics). It does not change the strength of jumps. These two facts allow Mario to vault through the air and fall much more slowly.
 * In Tales of Monkey Island Chapter 4: The Trial and Execution of Guybrush Threepwood, Guybrush uses one of the buttons on De Singe's Auto-Trepanation Helmet and gets shrunk a bit smaller than the size of a lab vole for a bit before growing back to normal size.
 * In Wonder Boy in Monster World the "Pygmy" equipment allows you to shrink to half your size and enter small passageways.
 * One section in Duke Nukem Forever features Duke shrunken to miniature size by an enemy's Shrink Ray. He then proceeds to kick ass against similarly-sized aliens.
 * Happens a few times in World of Warcraft (although only slight effects), with this quest being an exception: you're shrunk to the size of a rat.

Web Animation

 * In Banana Nana Ninja, Seppuku is eaten by an opponent and his size continually shrinks as he makes his way through her body, finally escaping and returning to his full size when she sneezes.

Webcomics

 * In U.F.O., Queen Pamela's hostages are shrunk down to the size of small rodents and put in a gerbil cage.
 * El Goonish Shive has this as a joke fetish in universe.
 * In Emergency Exit, Saya accidentally gets shrunk by Eddie's shrink ray.
 * Teeko from Chirault gets shrunk by an accidental spell from an unlicensed mage. Finding a way to return her to her former size seems to be a major plot point.
 * Dream Tales has a whole series of comics featuring shrinking men and women.

Web Original

 * Some size warpers in the Whateley Universe can do this. Sizemax can either be a 30-foot giant or a couple inches high.
 * Small Problem is a blog ostensibly written by Debby Small, who's 6½ inches tall.
 * The SCP Foundation deconstructs this with the resizing device SCP-1056. Shrinking or resizing people with it usually results in their brains and internal organs undergoing re-arrangement or ceasing to work correctly. (In particular, if you're shrunk, your brain becomes smaller and thus you become dumber.)

Western Animation

 * In the Ed Edd n Eddy music video The Incredible Shrinking Day (which isn't canon), Sarah makes a shrinking potion, spikes a pitcher of lemonade with it, and offers some to the Eds, who drank the concoction and shrunk so that Sarah can play with them.
 * Happened in one episode of Jackie Chan Adventures. A miscast "disappearing" spell shrunk both Jackie and bad guy Hak Foo.
 * Happened on Super Friends as well.
 * Happened on Star Trek the Animated Series episode "The Terratin Incident". In this one, it also affects the dilithium crystals that are crucial to the ship's warp drive as well.
 * Xiaolin Showdown did both this and its opposite: Lead character Omi uses the Changing Chopsticks to make himself huge in order to defeat the giant Cyclops and loses. When he tries to go back to his normal size, Omi shrinks to mini size for the remainder of the episode.
 * In the Tale Spin episode "The Incredible Shrinking Molly", Molly runs afoul of a wacky Mad Scientist and his shrinking machine. The scientist eventually shrinks Baloo, Rebecca and the Sea Duck so they can save her.
 * Additionally, a Tale Spin-based segment of a 1991 Disney On Ice show had Don Karnage using a shrinking machine to turn Mickey, Minnie, Goofy, Donald, and an Indiana Jones Expy into dolls.
 * This happened in the Darkwing Duck episode "Getting Antsy", where a crook was using a shrink-ray to loot the city using ants. Darkwing ends up getting zapped and reduced to the size of an ant for most of the episode and gets shrunk a second time near the end, where he ends up coming up with an unusual way of saving the day.
 * Chip 'n Dale Rescue Rangers features this reversed in one episode by Professor Nimnul to make ordinary bugs huge to fake an alien invasion, and more-or-less used straight in a later episode when some mob goons steal his device to shrink and steal buildings. In both cases, the Rescue Rangers, remaining their normal size (apart from Zipper in the earlier episode), thwart the bad guys.
 * Finally both played straight and reversed in another episode, where Chinese big bad used shrinking ray to increase size (and luxury) of cars, and then import sell them. By the end of the episode, Rescue Rangers grow to the size of a human, and then back.
 * In Aqua Teen Hunger Force, Frylock invents a shrink ray to shrink down a huge microchip, which is eaten by Meatwad. Out of options on how to get the chip out of Meatwad, Frylock gets Shake to shrink him, but Shake abuses the ray for his own amusement.
 * Danny Phantom episode "Micro Management" where Jack shrunk Danny, Skulker, and accidentally, Dash down to size. Had the added bonus of Danny slowly losing his powers because of it, risking his Secret Identity to the local Jerk Jock as the two tried to make their way up with The Hunter in pursuit.
 * The 1967 Fantastic Four cartoon took this to a whole new level, shrinking the heroes until they wound up in a subatomic universe, then shrinking them some more, making them tiny within that context.
 * The latest cartoon adaptation also did a shrinking episode, but they were able to reverse the effect (with help from Ant-Man) before it got anywhere near that far.
 * The animated version of Mork and Mindy did this plot as well; when Mork shrunk, he found himself in a microverse populated with warped (or even evil) duplicates of his friends.
 * The solo 1980s Spider-Man cartoon shrunk its hero in, aptly enough, "The Incredible Shrinking Spider-Man".
 * Also done in the early comics, but turned out to be one of Mysterio's illusions.
 * Also done in 1994 series, as a part of Nightmare Fuel, during a nightmare.
 * Happened to Mario and Luigi in an episode of The Super Mario Bros Super Show.
 * An early episode of The Fairly Odd Parents had Timmy wishing to be small and exploring Vicky's body.
 * There's also an episode where he shrinks down to have a chat with his (not making this up) evil, undead, pet gerbil, only to discover that it's Ax Crazy and out for revenge.
 * There's also the episode where Timmy wishes he could have one last adventure with his Crimson Chin doll, upon which Cosmo and Wanda shrink him down to toy size. Much of this episode is very reminiscint of the movie Honey I Shrunk the Kids.
 * Inch High, Private Eye was a 1970s series about a very short detective.
 * There was an episode of the Mega Man cartoon where Dr. Wily plotted to shrink cities so he could hold entire populations hostage. Naturally Mega Man and Rush were shrunk also.
 * In the Hi Hi Puffy AmiYumi episode "Small Stuff", our duo is shrunk after going through the dryer.
 * Occurs several times on Captain Planet.
 * This is the fate of anyone who messes with Reducto on Harvey Birdman Attorney At Law. Back off!
 * One episode of The Venture Bros cartoon has a shrink-ray gun Dr. Venture designed being sold at his yard sale. A later episode has Venture and Dr. Orpheus squaring off and betting over whether science or magic was better, deciding on shrinking as a challenge. Orpheus's incantations only shrink furniture, and Venture's shrink-ray gun is defective...testing it on Billy Quizboy has disturbing results.
 * The fairies in Winx Club who have earned their enchantix form can shrink into tiny versions of themselves (except for Bloom).
 * The Magic School Bus featured many episodes in which at least some (if not all) of the students shrinking to explore nature and its phenomena up close.
 * Phineas and Ferb do this to themselves in "Hide and Seek" to make the game more enjoyable, but Baljeet gets trapped in front of the air conditioner, and Candace has the shrinking machine.
 * Happens to The Herculoids in the episode "Tiny World Of Terror".
 * Space Ghost episode "The Evil Collector".
 * Spoofed in the Fanboy and Chum Chum episode "The Incredible Shrinking Fanboy", where Fanboy only thinks he's shrinking, after the flower where he marks his growth grows overnight. Yo uses this to her advantage, giving him a helmet with magnifying lenses to help with the illusion while she takes Chum-Chum to her room to play with.
 * Nightmare Ned did this where Ned was being tormented by a pair of Enfant Terribles.
 * Re Boot did this several times. First for a Fantastic Voyage, then twice more in games where everything but the main characters is scaled up to make them appear shrunk.
 * Happens to Applejack in the My Little Pony Friendship Is Magic episode "Bridle Gossip".
 * The Alvin and The Chipmunks movie "Funny We Shrunk the Adults" is one where Dave and Miss Miller are shrunken by Simon's "matter compacting" ray. At the same time, the Chipmunks and some neighbor kids who they are trying to impress are wrecking the house with their rowdy playing and bringing in things like a circus, including the animals. In fact, it was the rowdy playing that made the shrink ray turn on and zap Dave in the first place.
 * On an episode of Tiny Toon Adventures, the cast shrinks down to rescue one of Furrball's fleas from a vicious bedbug, but not without Lampshade Hanging.
 * Micro Ventures from The Banana Splits
 * In an episode of Eek the Cat called "Honey, I Shrunk the Cat", both Eek and Sharky were accidentally shrunken down by Elmo the elk's shrinking machine. After a failed attempt to grow back to their normal sizes, Eek and Sharky put some astronaut suits on and go to a sick president's nostril and travel inside his head to get a raisin off his brain (despite growing a little bigger amount every single time). After Eek and Sharky remove the raisin, the president sneezes them out of his nose. They did grow back when they eventually fly out the window and crash into the ground.
 * In the Princess Gwenevere and The Jewel Riders episode "Full Circle", after the villainess Lady Kale tries to harness the ultimate magic of the Crown Jewels, it becomes too much for her and the power ends up shrinking her in size before she fades out to dust.
 * Happens in The Jetsons once. It's George who gets shrunk.
