Jake has a Croak Dream involving a rocket ship and a Banana Man. After he wakes up and tells Finn about the dream, they hear someone knocking at the door. Finn looks out the window and sees the Banana Man and they decide to follow him to his house. After firing arrows at him to try to scare him away, they find his rocketship in his backyard. Jake tries to ride it, despite Finn trying to convince him not to, because he says it's his destiny. The rocket creates a hole, which Jake, Finn, and the Banana Man fall down. They fall into a pool of water which recreates Jake's dream, only Finn is there so the Croak Dream does not come true. They find out that the Banana Man only wanted to borrow some sugar.
