Tree Fort

The Tree Fort is Finn, Jake, BMO, and Neptr's home, and where they can usually be found when they aren't adventuring. It was formerly owned by Marceline as revealed in "Evicted!" It includes a living room, a bedroom, a kitchen, a pond, a well, a bathroom, a chicken coop, an attic, a storage cave/garage in the episode "What is Life?" a secret place in the episode "Dad's Dungeon" and a wide look-out view.

The tree
The tree itself is a species of willow, most likely a Weeping Willow. It appears to be completely hollow. The entire interior of the tree trunk is covered in boards.

Entrance/treasure room
The entry to the tree house is filled with all the treasure Finn and Jake have collected on their many adventures. Minus all the heaps of gold, the room is a simple empty room with a wood front door on one end, and a ladder leading up into the hollow trunk of the tree on the other.

The treasure in the entrance seems to include old TVs, VHS tapes, a unicycle, lots of gold, a Nintendo Entertainment System (NES) complete with several games, and a few other unusual things.

The entrance can best be seen in the episode "Video Makers" when Finn is looking for a video camera.

Boat
Seen mostly in the episode "Slow Love," Finn and Jake keep a boat as a type of look out view at the very top of a branch at the top of their Tree Fort. It has  an umbrella, a dining table and four chairs, a lamp, a carpet, a yellow-red telescope, a tripod, and other small objects in it. It also appears in "Power Animal" at the roof party and "Dad's Dungeon" when Jake turned into different things for Finn and BMO.

Roof
The top of the tree that the tree house is built on.

Although the roof appears to be the top of the tree's canopy, it is a solid surface. Therefore, it has been used for parties and star watching as seen in "Power Animal" and "Incendium" as well as a solid surface for Marceline in "Marceline's Closet," towards the end of the episode, when Marceline is trying to imitate an owl sound, while lying there. She was spying on Finn and Jake, and was seen right after Jake sees Finn (vice versa) and the duo scream.

Bathroom
This room was seen in only four episodes, "Marceline's Closet," "Five Short Graybles," "In Your Footsteps" and "Davey." It is possibly located near the bedroom. It consists of one bathtub/shower, a mirror, and a toilet. In "Marceline's Closet," it shows it not having a door, but it has animal skins hung up in a doorway. This episode shows it being near their bedroom. In "Slow Love," it shows the doorway with animal skins if you look through the window, this may prove it is located in their living room. In "Five Short Graybles," it has a door and it is located in the hollow log in their kitchen. In "Davey" it is the place where Finn had cut his hair.

Bridge
Seen in "Rainy Day Daydream," this is where it links the "attic," and the living room. There are two bridges on the fort as seen in zoom-outs of the tree fort.

Kitchen
This was seen in many episodes such as "Beautopia," "Conquest of Cuteness," and also in the game, Legends of Ooo. It has a couch, a table, a picture (see 'Trivia' section bullet point 4), a stove, and other kitchen appliances. The room must be on the ground level since Susan was standing on solid grass when she broke through the wall. This room is also referred to as a second living room, see "Living room" section above, and the house breakdown diagram in the gallery.
