The Tree House is a "guard outpost"[citation needed] on the edge of the Candy Kingdom, as well as the home of Finn, Jake, Shelby, BMO, and Neptr, and where they can usually be found when they aren't adventuring. It was formerly owned by Marceline, as revealed in "Evicted!" The fort includes a living room, a bedroom, a kitchen, a pond, a well, a bathroom, a chicken coop, a treasure room, an attic, a storage cave/garage (shown in "What is Life?"), a secret place (shown in "Dad's Dungeon") and a wide look-out view.
In "Come Along With Me," the Tree House was destroyed by one of GOLB's monsters and later in the episode Finn and Jake planted another tree with Fern's remains, as it was his dying wish. Fern's tree is similar in appearance to the old one, with the exception of a home inside it, and it also has a new Finn Sword growing out of it. One thousand years later, this tree had grown to a massive size before Shermy and Beth climb to the top and claim the sword.
