About this Adventure Time episode:
Adventure Time - Jake the Dog is the 2nd episode of Adventure Time season 5.
In the fourth season finale "The Lich", Finn and Jake are tricked by the Lich into opening a portal to the multiverse. After the Lich passes through, Finn and Jake give chase in the fifth season premiere "Finn the Human". Finn, Jake, and the Lich discover a mysterious being named Prismo that grants wishes. The Lich wishes for the extinction of human life. Finn, however, wishes that the Lich had never existed, and is transported to his wish-altered reality, in which he is a peasant boy who discovers the Ice King's magic crown. Finn puts on the ice crown and becomes corrupted by its power, going mad. 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. Jake, however, falls into a mutagenic puddle and is mutated into a creature similar to the Lich, which attacks Finn.
In the Time Room, Prismo reveals to Jake that Finn has been transported to a separate, altered world based on his wish that The Lich never existed. Together, they watch the events in Finn's world on Prismo's television, and Prismo asks Jake what he would like to wish for. Jake wishes for a sandwich, but Prismo urges him to use his wish on something important, such as helping Finn. After a conversation, the two decide to hang out; Prismo mutes the TV and the two begin to ignore the events happening in Finn's timeline.
Eventually, the Cosmic Owl joins Prismo and Jake, and the two chat in a hot tub. While reaching for chips, the Cosmic Owl unmutes the TV, and Jake realizes that Finn is in trouble. Prismo explains that Jake can save Finn by wishing, but that his wish must be very specific, as Prismo's wishes have a tendency to have a monkey's paw—an ironic twist—connected to them. After coaching by Prismo, Jake wishes that the Lich's original wish had been for Finn and Jake to return home. Prismo grant the wish, and Finn and Jake are indeed transported back to Ooo. Finn has no recollection of his time in the alternate reality, but Jake does.
