Prismo needs Finn and Jake’s help to stop a catastrophic event from happening somewhere in the multiverse.
Tropes
- Alternative-Self Name-Change: The Farmworld version of Billy is named Bobby.
- Apocalypse How: Implied that if Farmworld!Finn manages to open a portal to the multiverse, it will cause a Class X-5, possibly Z. Exactly how is not explained, but as it involves the Lich, it wouldn't have been pretty.
- Belated Happy Ending: Farmworld Finn and his world were left in extremely dire straits at the end of "Jake the Dog"—. The best thing that happened to it was that whole timeline being seemingly erased for the previous one. Here it turns out it wasn't erased, which allows Finn, Jake, and Prismo to destroy the Lich and alter reality so Ice King's crown was destroyed before Finn ever used it.
- Bittersweet Ending:
Fridge Horror says the Farmworld's Belated Happy Ending isn't entirely happy. The Mushroom Bomb still went off and the damage done by Finn, the Lich and the Destiny Gang stay how they are. Given the proceedings of the main timeline, though, it's likely that, in a few hundred years, things will be even better off than the main timeline due to the Lich having been taken care of much earlier. - Celestial Bureaucracy: Prismo emphasizes the fact that he does have a superior he answers, and one that would hold him responsible for the multiverse getting screwed over by the Lich (and not just him given how by proxy, both Finn and Jake would be for it too.) Considering Prismo's capabilities, it says a lot on how powerful Prismo's superior must be, especially if it takes the destruction of the multiverse to get them involved.
- Continuity Nod: Finn's hand-thorn becomes a grass whip once again, this time to defend Jake from the Lich and free himself when he's immobilised in ice.
- Freeze-Frame Bonus: Doubles as Foreshadowing. The Maid has an additional instruction on its base that Finn neglects to read out: "P.S. don't mess around and point the Maid at your buddy, you goof. You already screwed up once." Ultimately, the solution Finn arrives at is to use the Maid on the Lich-possessed Farmworld!Jake, turning him back into a normal dog.
- Furry Confusion: Jake mocks his Farmworld counterpart, being a normal dog, and he's not really sure what dogs are into.
- Hijacked by Ganon: In the first half of the episode, it seems as though Finn and Jake will have to defeat Farmworld!Finn to prevent him from destroying the multiverse, but it turns out he was just a pawn of the Lich, who is the real villain.
- Knight Templar: Farmworld!Finn, driven mad by the Ice King's crown and the loss of his world, and manipulated by The Lich, believes that he is "saving" his people by encasing them in ice, that what he is doing will save his world and allow them to live across the entire multiverse - only when the portal is opened does the Lich show his hand and prompt Farmworld!Finn's rejection of him.
- Meaningful Echo: When explaining why he can't bring himself to destroy Farmworld!Finn, Finn says "That is me." "That's me" repeats Finn's reflection in the Finn Sword, to which Jake responds that he heard him the first time.
- Obviously Evil: The Lich in Farmworld!Jake's body. Jake notes that he's not even trying to hide it, as he still has his original skull face.
- Oh, Crap!:
- Prismo appears to be on the verge of a panic attack throughout most of the episode. This is due to the multiverse being threatened and that if it does go, his mysterious boss would hold him responsible.
- The Lich gets one when he sees the Maid about to hit and atomize him.
- Poor Communication Kills: Zigzagged. Prismo deliberately neglects to explain what he meant by saying "take care of" Farmworld!Finn. Although Finn initially intends to use the Maid to heal his alternate self's madness, Jake seems to think they're meant to kill him instead, an option neither of them can bring themselves to do in spite of the danger posed by his plans. They instead decide to try to steal the Enchiridion and solve the problem nonviolently - it doesn't work, and the Finns ultimately use the Maid to destroy the Lich.
- Retcon: This episode retcons the animation error in "Jake the Dog", where Simon's corpse was wearing the crown even after Finn took it. Here it is explained that Prismo did a Cosmic Retcon and placed the crown back on his head to destroy it forever.
- Sequel Episode: To "Finn the Human"/"Jake the Dog".
- The Un-Reveal: We never find out what was negating Prismo's powers in the alternate reality, or the identity of Prismo's boss of whom he is terrified of having to answer to should reality be destroyed, at least until the spinoff Adventure Time: Fionna and Cake.
- Wave-Motion Gun: The Maid turns out to be one.
- Wham Line: Prismo gives a bit of a surprising one when discussing Ice Finn's multiverse portal attempt:
Prismo: Now if that happens, my boss,
let me repeat that, My. Boss. will hold me responsible. And by proxy, ya'll both will be in the dip too.
- Wham Shot: Big Destiny walks up to the portal in a daze with a bag of gems, prompting the confusion of the main characters... until the Lich walks up behind him.
