Wario forest

It was originally intended for the Wario Ware and will not appear once obtained, since it is removed from the Gamecube after being obtained. If Wario is in an elevator (on the top), Wario can fall from the ceiling and enter a room with a Wario Forest, thousands of knocks on the door can be heard during this. The Wario Forest will appear and Wario will appear as a gray ghost, with the Wario Ware. There is also a secret room with Wario in the middle of it.
