The Creeps

"The Creeps" is the twelfth episode in season three of Adventure Time.

Synopsis
Finn and Jake attend a who-dun-it murder mystery dinner with several friends where one of the attendees is a murdering ghost. However before the night is over, the tables are turned as real horrors begin to emerge.

Plot
Finn and Jake headed to a castle for a party they were invited to by an unknown host. Outside the door is a box of disguises for them to wear. When they head inside they find Princess Bubblegum, Lumpy Space Princess, Cinnamon Bun, and Beemo inside. They discover a note on CB's back. Finn reads it telling them that their host is a ghost that will take over one of their bodies and kill the rest of them. CB tries to leave, but as he tries to open the door, the lights flicker. When they come back on, there is nothing left of him but a skeleton.

Jake thinks Finn planned this from his birthday prank on Finn in "Mystery Train," but Finn denies it. Finn brings the remaining party guests to the staircase and has Beemo take pictures of them with his ghost detection to see who is possessed. Jake doesn't blink when his pictured is taken, making everyone believe he is the ghost until Beemo confesses it has no ghost detection gear and just likes taking pictures.

Jake suggest they get candles in case the lights go out again, which they do. He and Beemo head into the basement where Beemo disappears. Everyone panics and they hear LSP screaming in the bathroom, only to find out she was using it.

They go to the dining room where they begin to point fingers at each other. Jake accuses LSP and that she has to tell them why she broke up with Brad to prove herself. She refuses on the grounds that they didn't know what happened between them. Finn wanted to tie her up with PB agreeing with him, causing her to be accused of being possessed(LSP then continually interrupts; confessing that she broke up with Brad because he kissed her on the mouth and she wasn't ready).

Finn then asks PB to recite what he wrote her two years ago as a birthday card, but she denies because she can't remember. Then a long tube of light passes through the roof and through PB; causing her to melt. It also engulfs LSP and puts her in a painting. Finn then admits that this was a prank, but this wasn't part of it. Finn checks the closet where CB and Beemo are supposed to be hiding, but instead find their scatter remains. Finn runs to an upper room but Jake is engulfed by the light. Out of bookshelves, Ghost Lady appears and tries to get Finn, but he escapes by breaking through a wall.

In the observatory, Finn is cornered by the light, only to find out that it's Jake with Lady Rainicorn with all the guests in her body. Jake reveals that he knew about Finn's plan for months and set this up with Lady Rainicorn. Finn asks about the monster he saw and Jake believes he was just imagining it out of fear and they leave. After they leave on LR, Finn flashes back to the monster he saw and decides to put it in "the vault" and forgets about it.

Trivia

 * This episode is scheduled as part of Cartoon Network's Halloween-themed programming, and is "Halloween-appropriate" according to Adam Muto.
 * This episode is like a sequel to Mystery Train, done in a similar who-dun-it mystery style where strange murders occur within a confined space like a murder mystery book by Agatha Christie called And Then There Were None.
 * The title card may also be a reference to the game Clue since the various murder weapons the guests are holding, and their outfits resemble those of in the game.


 * thumb|300px|right|AnimaticIt is revealed that Cinnamon Bun has feelings for LSP, due to the fact that Cinnamon Bun was hitting on her
 * Each character had a party name. Finn is Prince Hot Bod, Jake is Randy Butternubs, PB is Lady Quietbottom, Beemo is Professor Pants, LSP is Duchess Gummybuns and Cinnamon Bun is Guy Farting.
 * Cinnamon Bun's name is shortened to CB for the first time.
 * At some points in the episode Finn appears to be the same height as Princess Bubblegum. The reason for this has been suggested by the Adventure Time staff to be an animation error, or Finn may be wearing lifts.
 * In this episode, Lumpy Space Princess reveals why she broke up with Brad.
 * At the top of a staircase, a portrait's plate reads: 8•18•12. This could be the date that the portrait was painted.
 * On the bottom of a painting, it says La Caza Del Zorro which means, in Spanish, The Fox Hunt.
 * When LSP is pushed into the painting by the ghost, she drops her phone. In spite of this, the lights go back on and LSP is in the painting; with her cell phone in her hand.
 * This episode features a more defined character style with elbows and more distinct knees, this is most likely for more dramatic expression of the characters' emotions (Similar to when Finn's face deforms to emphasize emotion)
