Farmworld

Farmworld is the universe that was created by Finn while he and Jake were trying to stop the Lich in the episode "Finn the Human" when he wished that the Lich "Never even ever existed". So the world was altered as if the Mushroom War didn't happen. Not much is known about the dimension it is located in or about the inhabitants. The only known inhabitants are Farmworld Finn's mother, Farmworld Finn's father, Farmworld Jake, Farmworld Finn's brother, Farmworld Finn, Destiny Gang and few others.
