The treehouse! Or the tree fort, depending on who you ask

You can buy a poster of this if you want, which is pretty cool I think

As with any cartoon house, it was hard to get everything perfectly accurate, as the layout and size of the treehouse changes from episode to episode. I even made an animated, slightly interactive version, you can check it out on my deviantArt: jollygengar.deviantart.com/art/The-Treehouse-521180563
