Doubleface is a short creature, an anthropomorphic head with tiny arms, legs and a face on both sides. The way they actually face can only be determined by the orientation of their hands and feet. The faces display traditionally masculine features, distinguishing them from the Giant Head and Fetuses found in other areas of the game. They can only be found at the Bright Moon Cottage.
Doubleface can spawn in two areas of the cottage: behind the bar, and in the front yard next to the tree. Multiple Doublefaces can occupy the cottage at once, sometimes even spawning in the same location and overlapping each other.
Doubleface remain stationary until you approach them. The one behind the Bar dances in place (or occasionally grows exceptionally thin and long), while the other will begin running toward the exit. Linking with the bar usually puts you in the Violence District. Unlike most other objects in the game, the player does not get linked if a Doubleface touches you on its own.
