Chocolate World is an area found actually in the Forest World, interacting with a white(sometimes mixed or dark) chocolate bar.
In previous versions, this area also could be accessed via The Hand Hub
Features
As its name suggests, Chocolate World's floor consists of squares of dark or white chocolate. Blocks of chocolate also float around the background and foreground.
There are a few portals here as well. Interacting with the white chocolate bar will transport you to Forest World, the mixed chocolate bar will transport you to the Theatre in the Dark Room and the pink cone head transports you to the Stone Maze. The cone head can also be killed with the Chainsaw.
There is also a small rabbit running around which acts as a portal to the Hospital, and there a number of moving red hour glasses.
