Goosebumps/YMMV


 * Adult Fear: The Horror at Camp Jellyjam. Imagine being a parent who has sent their kid to a seemingly legit, if not oddly named, sports camp. Then you've lost contact with the camp. Then you learn that your children have been
 * Canon Sue: In the TV version of You Can't Scare Me, Courtney comes off as this.
 * Complete Monster: Many, but not all of the villains, including Slappy, Ahmed from The Curse of the Mummy's Tomb, the Masked Mutant, Mr. Toggle from Piano Lessons Can Be Murder, and the Lord High Executioner from A Night In Terror Tower have their moments (although Slappy is more a Jerkass until Fridge Horror kicks in), but Mr Toggle and Ahmed are the truest complete monsters. But one particularly noteworthy is the Big Bad of Goosebumps Horrorland, called the Menace.
 * Don't forget Sarabeth (the Cat) from Monster Blood. She becomes this when even if the grandmother sacrifices herself to the Monster Blood, and ultimately eliminate her control over her, Sarabeth still tried to command it to kill the children.
 * Alexander in Deep Trouble counts too.
 * Ensemble Darkhorse: Slappy
 * Evil Is Hammy: The Masked Mutant and Slappy come to mind, especially in the TV show.
 * Fridge Horror: The ending of is much more disturbing to read as a seventeen-year-old than as a twelve-year-old, for instance. This example also counts as a Late to The Punchline moment. For those who haven't read it:  Also in The Curse of Camp Cold Lake, at first you think the girl on the cover is supposed to be Della, the ghost girl that torments poor Sarah Maas all story long. Until you read and find Della looks perfectly normal but transparent. This girl is not transparent and looks like a female version of the Skin Taker from Candle Cove. The ending implies that.
 * Hell Is That Noise: The Chalk Closet.
 * Hilarious in Hindsight: The monster in How to Kill a Monster sure does look a lot like The Evil Thing.
 * In the Tv Episode of "Night Of The living Dummy 3", Zane (played by a young Hayden Christiansen), Slappy turns him into a dummy and makes a pun that he looks wooden. Hmmm, Hayden Christansen being seen as Wooden...
 * Paranoia Fuel: Not only some of the stories but some of the cover art as well if you look a little too much into it.
 * Recycled Script: Taken to ridiculous lengths with the number of summer camp stories:
 * Welcome to Camp Nightmare (Original Series #9): A boy goes to a summer camp said to be haunted by a monster in the woods and his bunkmates keep getting injured and disappearing.
 * The Horror at Camp Jellyjam (Original Series #33): A brother and sister on a road trip crash their trailer into a sports camp where everyone is obsessed with competing and winning in sports
 * Ghost Camp (Original Series #45): Two brothers go to a summer camp where everyone is a ghost and the only way they can escape is to possess the body of a living being.
 * The Curse of Camp Cold Lake (Original Series #56): A girl at a water sports camp finds herself haunted by a murderous Yandere ghost girl who can't go to the afterlife unless she has a buddy.
 * Fright Camp (Series 2000 #8): A group of horror movie fans win a trip to a camp that is said to be home to a horror movie director's creations.
 * Return to Ghost Camp (Series 2000 #19): A boy switches places with another camper on his way to the ghost camp from the original series and enjoys living his life -- until.
 * Escape From Camp Run-For-Your-Life (Give Yourself Goosebumps #19): You (the reader) find yourself in a camp filled with zombie children.
 * Welcome to Camp Slither (HorrorLand #9): A brother and sister find themselves in a camp infested with snakes.
 * So Bad Its Good
 * Tastes Like Diabetes: A Holly Jolly Holiday, about a disgustingly sweet Christmas movie which gradually turns viewers into the protagonist, Susie Snowflake. People who enjoy that kind of stuff may actually be happy to turn into Susie Snowflake.
 * Tear Jerker -- The ending of The Ghost Next Door (both the book and the TV episode).
 * Toy Ship:
 * Since almost every book has at least one major character in each gender, it's to be expected that this would happen at least once.
 * Another overt love interest turns out to be manipulative and evil in.
 * Yet another one is Lilly in Attack of the Mutant. (She, though.)
 * Played straight in How I Learned to Fly.
