Well, forget about the treehouse, I don't need it, because Doc and I will soon be moving to the coolest place on Earth. Althought it is true that "A voyage to the Gunkanjima-island is prohibited
currently," it won't be if, as Doc suggested, we BUY it. I think we might have to have a bake sale or something, but I have faith that we will soon be ensconced in our island stronghold with our cats and our consorts and a tank full of sharks with frikkin' laser beams on their heads.

More information about the island is here.
