Happy Town is a psychedelic looking area within the game. Throughout the area, there are many abstract shapes and strange looking monuments. Many of these things have a tendency to lean towards an upper or downer dream, and several are specifically linked to other areas, either within Happy Town itself, or somewhere else. A small octagonal castle is located in the center of this area with a path lined with trumpeters leading up to it. A train track can also be seen winding throughout the area, complete with a train that comes through a tunnel. Small mazes with knee-high walls are present, one with a spinning question mark and a number of other monuments. The textures in this area are also very peculiar, and each one makes a different strange footstep noise when you walk on it.
