The Big Tree was a mysterious giant tree found in the north of Booty Island, which hosted an empty treehouse. Some people had build a shack nearby as well as a couple of treehouses and an observatory on its top, as well as a series of steps to access its top. It was abandoned and only a seagull made its nest there with stolen map pieces it salvaged. When Guybrush Threepwood firstly attempts to climb the tree, he falls and hits his head, and has a dream with his parents.
