Imagination Zone

Throughout Adventure Time, numerous imagination zones have appeared, sometimes interacting with the real world in unexpected ways. This article contains a list of these imaginary places.

Ice King's Imagination Zone
The Imagination Zone is a place visited by Ice King. First named in "What is Life?," it is a magical space where he can imagine anything he wants, usually beautiful princesses. He also imagines he and Neptr enjoying a sunset as father and son.

The Ice King can teleport himself and others into his Imagination Zone, although he also seems to go there involuntarily whenever he's knocked unconscious by Finn, as seen in "What Is Life?" and "Prisoners of Love." It appears that Ice King cannot control who goes to the Imagination Zone, because Finn was able to travel there by grabbing the hem of Ice King's robes. The Imagination Zone seems to behave like an actual physical place rather than just something imagined. In "Prisoners of Love," the Cosmic Owl is encountered in the Imagination Zone, declaring Ice King a sociopath.

Dark Magician's Brain World
During the ending of "The Enchiridion!," Finn is sent to Dark Magician's "brain world" for a test of character. While it may or may not be the same place, it seems to function on a similar principle.

Finn's Imagination Land
In the episode "Freak City", Finn appears in a place similar to the Imagination Zone when the song "The Hero Boy Named Finn" begins. Finn also goes into an empty, white space in his imagination in "Rainy Day Daydream", which is referred to as his "Imagination Land." A Lyre Player and Bellamy Bug also appear there.

Galaxy of Flavors
"The Other Tarts" begins with Princess Bubblegum describing a "Galaxy of Flavors" over a scene that resembles outer space filled with floating confections. Later, the Royal Tart Toter, in spite of being blind, deaf, and quite insane, perceives himself to be drifting away though the same galaxy. For some unknown reason, Lumpy Space Princess can be seen hitching a ride on a passing doughnut, though whether she is really there or just imagined is unknown.

Interestingly, title card designer Andy Ristaino confirmed that the title card of "Five Short Graybles" depicts the Galaxy of Flavors. Although the title card does not seem to fit within the episode's actual story, it appears to show Cuber inside a crystalline structure or spaceship, traversing the Galaxy of Flavors, which contains floating cupcakes, hot dogs and sushi.

Jake's Croak Dream
Jake's Croak Dream and croak dreams in general might be affiliated with this phenomenon, being derived from the deeper parts of the mind like previous examples as well as associated with a sighting of the Cosmic Owl.
