The Museum was an area found in older versions of the game. As of 0.097f, it has been completely replaced with the Dark Museum.
Features
It is an area with multiple rooms, blue floors and walls and oddly shaped doorways. There are a number of items on display including a Buddha statue and a cross. The Glasses effect could be obtained here by interacting with the glasses on the pedestal in one of the rooms.
By going down from the main area (pictured), it could take you back to the ticket booth in Flying Fish World.
