Stuck inside the treehouse during a sword storm, Jake builds a pillow fort while Finn goes to a different world.
Tropes
- All Just a Dream: When older Finn "dies", he wakes up in the original world, and goes to tell Jake about the weird dream he had, only to forget about it. Unless it wasn't a dream at all...
- Ambiguous Situation: It is unknown whether or not Finn's time in Pillow World was all just a dream.
- Artificial Limbs: Another incarnation of Finn that loses his right arm and has it replaced with a prosthetic. In this case, a pillow arm.
- Continuity Nod: Finn and Jake are stuck inside due to a knife-storm, just like in "Rainy Day Daydream".
- Carpet of Virility: Adult Finn displays one, along with a macho beard
- Dead Guy Junior: Lost rather than dead, but Finn's two children are called Jay and Bonnie, implying that he named them after Jake and Bonnibel (PB's rarely-used personal name.)
- Dying to Wake Up: At the end of the episode, Finn wakes up back in the pillow fort he and Jake made shortly after he died of old age in the Pillow World, revealing that his experiences there were All Just a Dream.
- Early-Bird Cameo:
- CMO makes his first appearance in this episode.
- GOLB makes his first appearance near the end of the episode.
- Eldritch Abomination: When Finn dies in the pillow world, he passes by a red, four-eyed, trapezoid-headed creature on his way back to his reality. According to the creators, its name is GOLB.
- Eyes Always Shut: Quilton, the Pillow People leader and Finn's father-in-law, always has at least one eye shut.
- Foreshadowing: Jake and BMO discuss his lack of connection with his children due to Rainicorns' rapid maturing.
- Freeze-Frame Bonus: The newspaper Rasheeta shows Finn has some amusing filler text.
- Gasshole: The Hermit Guru Rasheeta farts to encourage Finn to leave his hut.
- Girl of the Week: Roselinen, who Finn later marries and has children with. However due to its All Just a Dream, it's unknown whether it's real or not.
- Godiva Hair: As elderly Finn's spirit flies nakedly back to Ooo, his beard covers his naughty bits.
- Half-Human Hybrid: Finn and Roselinen's children, Jay and Bonnie (being half pillow, half human).
- I Choose to Stay: After visiting the Guru, Finn decides to stay in the Pillow World with his wife and children.
- Mind Screw:
- Jake twists his arm around his face like a drill which opens to reveal a smaller Jake. Definitely one of his more bizarre transformations.
- The very fact that Finn manages to get lost in the Pillowverse, find a girl, get married, have children, embark on a quest to get back to his home-world, grow old, and die, only for this entire thing to (possibly) be a dream...it left more than a few people saying "Huh?!"
- No Challenge Equals No Satisfaction: Present in a downplayed way. After a whole lifetime in a land of Pillows where everything comes easy to him and nothing is really that challenging, Finn's assessment minutes after leaving is "Eh." Character-building aside, the Pillowverse life flat-out wasn't even worth remembering because it was all too soft.
- Our Dragons Are Different: The Blanket Dragon is made of pillows, but it resembles a more traditional dragon shape than the one in the Land of Ooo.
- Planet of Hats: The Pillow World is filled with pillow people with Roselinen being the token humanoid.
- Shout-Out:
- Title Drop: "Puhoy" is a greeting used by Quilton, mayor of the pillow village.
- Vanishing Village: Portals between Ooo and the Pillow World only have brief and occasional existence.
- Whole-Plot Reference: To the Taoist parable The World Inside A Pillow
, although "pillow" in that referred to the pottery headrests used in medieval China. The involvement of Jonathan Frakes as the voice of adult Finn also suggests that the episode refers to the popular Star Trek: The Next Generation episode 'The Inner Light', in which Captain Picard has a similar experience thanks to a telepathic alien cultural archive. - Year Inside, Hour Outside: Finn grows old in the Pillow World while only an hour or so passes in the Land of Ooo. It could be that this is because it's a dream.
