After staying up for a week straight, Finn and Jake have difficulty sleeping, because a creepy horse is constantly watching them from outside their house.
Tropes
- Black Comedy: The montage implies Finn and Jake inadvertently helped Peppermint Butler cover up a murder he committed.
- Body Horror: When Jake blindfolds the horse, the horse's eyes wriggle out from under the blindfold in a rather unsettling way.
- Captain Obvious: Finn demonstrates his mastery of the obvious:
- Downer Ending: “I’m….still not happy.”
- Epic Fail: The Ice King casts an ice-control spell with a very intimidating lightshow, but the only ice nearby is a few ice cubes in Finn and Jake's larder, which fly out and hit them very unimpressively.
- Fourth Wall Psych: Finn tells Jake he feels like they're being watched. He and Jake turn to the camera... and the camera cuts to show they're looking out the window at the Staring Horse.
- Foreshadowing: At the beginning, Finn and Jake recall the adventures they've had over the past week. One of these involves rescuing a princess from the Ice King, who says "I just want to be happy!" Turns out, he's wearing the horse costume to try to find out how Finn and Jake are so happy.
- Hijacked by Ganon: The horse is the Ice King in disguise.
- Ineffectual Sympathetic Villain: The Ice King reveals once again just how pathetic he is, spying on Finn and Jake just because he wants to figure out the secret to how they're so happy.
- Insomnia Episode: Finn and Jake are exhausted after adventuring almost nonstop for a week, but can't sleep because of a weird horse staring at them from a nearby hilltop.
- Kubrick Stare: The horse just stares blankly and unsettlingly at Finn and Jake.
- Literal Ass-Kicking: Finn ultimately plans to get rid of the horse by kicking it in the bottom. It leads to him discovering the horse is really Ice King in disguise.
- Long Speech Tea Time: The Ice King gives a long speech about how unhappy he is, and how much he envies Finn and Jake and wanted to understand how they can be happy. At the end it's revealed that Finn and Jake have gone to sleep.
- Noodle Incident: The various adventures Finn and Jake have had over the last seven days, including rescuing princesses, slaying monsters, capturing bandits, and feeding hungry ducks.
- Plug the Volcano: In a flashback, Jake plugs an active volcano with a bolder to save a couple's house.
- Released to Elsewhere: When Jake suggests disguising the horse as a bunny so hawks will eat it, Finn is horrified. Jake then tells Finn that the hawks will take the horse to a lovely island somewhere.
- Shout-Out: The Horse is based on Fat Pony from Hark! A Vagrant.
- Sleep Cute: Finn, Jake, and the Ice King at the end all sleep together in a pile.
- Ye Olde Butcherede Englishe: Finn talks this way while trying to politely ask the horse to leave, "diplomat style".
Finn: Pardon me, horse, I beseech thou to split from mine land this night. But I welcome thee to come back for some luncheth some other day, okay?
