The Gravity Falls wax museum is a showcase in Gravity Falls, and part of the Mystery Shack. It once held many cursed wax figures based on famous people from history. These wax people come to life whenever the moon is waxing. The wax figures were trapped until Soos found the secret door.
The museum was opened some time before Mabel and Dipper arrived in Gravity Falls. For a long while, it made a sizable amount of cash for Stan Pines; however, eventually people lost interest in it. This caused Stan to lock all of the wax figures up in a small room, which eventually was covered up with wallpaper.
About ten years later, Soos discovered the room while he was sweeping. After Mabel created a wax figure of Stan, he re-opened the museum. However, there was still very little interest in it, with people only arriving at the grand opening because he had offered them free pizza with admission and quickly leaving after being told there would be no pizza.
The museum was yet again closed after Dipper and Mabel destroyed all of the attacking wax figures except for Larry King's head, which, later, is seen hopping through the air duct and "talks" to Mabel when she asks Dipper which sweater she should wear.
