"Finn the Human" and "Jake the Dog" are the first and second episodes of the fifth season of the American animated television series Adventure Time.
The episodes guest star Ron Perlman as the Lich, Kumail Nanjiani as Prismo, Ming-Na as Farmworld Finn's mother, Cloris Leachman as Farmworld Marceline, James Kyson as Big Destiny & Trami, Eric Bauza as Tromo, and Jeff Bennett as Choose Bruce.
Finn is then transported to an alternate timeline, where he is a normal human living with his family and his dog, Jake, on a farm.
In the fourth season finale "The Lich", Finn and Jake are tricked by the Lich—disguised as their hero Billy—into opening a portal to the multiverse by using the Enchiridion.
The scene then shifts to the art style featured in the end of "The Lich", as part of the wish-created reality—known as "Farmworld"—in which Finn is a normal human living with his family and his dog, Jake, on a farm.
Picking up from the last scene from "The Lich", Finn is called by his mother and told to sell his beloved mule Bartram to pay off the family's debt to the Destiny Gang.
While going to town to the sell the creature, Finn and Jake fall down an opening in the earth and discover the long-dead skeleton of Simon Petrikov.
An aged and decrepit Marceline—who never became a vampire—reveals herself and tells Finn that Simon gave his life stopping a mutagenic bomb from exploding by freezing it in ice.
He attacks the Destiny Gang—who his family owed a debt as established in the previous episode—and put out the fires that they started, but his uncontrolled power causes the mutagenic bomb that Simon stopped to explode, destroying the surrounding area.
In the Time Room, Prismo explains to Jake about Finn being transported to a separate and altered world based on his wish.
For instance, the majority of the scenes with Prismo were created by Sanchez and Herpich, whereas "Finn going insane" was the product of Sugar.

[5] Likewise, he wrote that "Jake the Dog" focused "on humor and relationships", and had various "irreverent silly note[s]" that helped balance the episode's more serious story line.
[10] He called the collective episodes "the ideal testament to animation's glorious pliability in an commercial arena otherwise defined by restrictions.
"[10] Kohn felt that the show's exploration of "sad subtext"—such as the series' mysterious Mushroom War and the relationship between Marceline and the Ice King—and the characters' abilities to "deny the bad vibes their surrounding world invites" via "cheery songs and vibrant artwork" were some of the series' strongest points.
