The Treehouse is a location in Tim Burton's The Nightmare Before Christmas. It is the home of Lock, Shock, and Barrel, Oogie Boogie's three henchmen.
Background[]
Lock, Shock, and Barrel's treehouse is located just outside Halloween Town on the far side of the Spiral Hill. The tree is in the middle of a pit that makes up part of Oogie's Lair. A small rope bridge leads to a cage shaped elevator that carries the three up into the house and the chute (designed with broomstick eyebrows, swirl eyes, and a monster mouth drawn in chalk giving it a scary look) inside leads to his lair which they use to send items and/or victims such as Santa Claus down through it.
