The Simpsons: Night of the Living Treehouse of Horror was a Simpsons-themed video game created in 2001 by Fox Interactive, Software Creations, and THQ Inc. for the Game Boy Color based off of the show's Treehouse of Horror Halloween Episodes.
It's Halloween night, and the Simpsons are telling ghost stories in Bart's treehouse. When Homer's pathetic attempt at telling a scary story ends up boring the entire family to sleep, they find themselves having an out of body experience, landing in the world of the Treehouse of Horror, where every day is Halloween. The only way to escape is to get to the top of the tree, which is accomplished by making it through the levels of the game, each one based off of a classic TOH segment.
- Adaptational Villainy: In Treehouse of Horror V's "Nightmare Cafeteria" segment, Willie tried to save the Springfield Elementary kids from being eaten by the teachers and staff (and ended up with his third axe to the back of the special for his troubles). In the level based of the short, he's part of the staff actively hunting down Lisa.
- All There in the Manual: The plot of the game is only explained in the game's instruction manual that comes with it.
- Body Horror: The second level, "Flying Tonight" has Maggie take up Bart's role in "Fly vs Fly."
- The Cameo:
- Early-Bird Cameo: Principal Skinner shows up as the second-to-last boss in "Plan 9 From Outer Springfield" before becoming the main villain in "Nightmare Cafeteria."
- Gainax Ending: The game ends with each member of the family falling out of the tree, only to be abducted by an alien spacecraft (presumably Kang and Kodos') before cutting back to the title screen.
- Gotta Rescue Them All: "Nightmare Cafeteria" sees Lisa sneaking around Springfield Elementary trying to find the keys to the cages holding Bart, Milhouse, Martin, Uter, and one of the Sherri/Terri twins before they're eaten while trying to avoid getting caught by Principal Skinner, Groundskeeper Willie, Mrs. Krabappel, Miss Hoover, Mr. Largo, and Lunchlady Doris.
- Haunted House: The first level sees Bart needing to rescue Santa's Little Helper from the attic of one.
- "King Kong" Climb: Given that the final level is "King Homer," this trope is obviously coming. And unlike in the actual episode, Homer makes it to the top this time.
- Puzzle Boss: Unlike the other bosses in the gamenote , Vampire Mr. Burns in "Vlad All Over" doesn't have a health meter to drain to defeat him. Instead, Homer has to jump on the curtains in Burns' basement coffin room, opening them up and letting sunlight into the room, gradually forcing Burns into the corner upon which Homer opens the final curtain, bringing sunlight down onto Burns and disintegrating him.
- Shout-Out: Homer's robot body in "If I Only Had a Body" resembles Bender's body.
- Theme Tune Cameo: Three different 8-bit versions of The Simpsons theme are used as background music for "Bad Dream House"/"King Homer," "Plan 9 From Outer Springfield," and "If I Only Had a Body."
- Zombie Apocalypse: "Plan 9 From Outer Springfield," a combination of the plots of "Dial 'Z' for Zombies" and "The Homega Man" sees the entirety of Springfield become zombies except for the Simpsons. Playing as Marge, the player needs to make it back to the Simpsons' house blasting zombies and fighting bosses based off of zombie versions of Apu, Moe, Principal Skinner, and Krusty the Clown along the way.
