Cheese

Cheeses are common items found by Luigi in Luigi's Mansion. They are placed in rooms rather spontaneously. If Luigi selects this cheese with the Game Boy Horror with the A button, a very rare and valuble Gold Mouse will appear. The mouse will then appear whenever Luigi crosses a randomly selected mousehole, which will be announced by a distinct chime; Luigi can suck this mouse up for lots of money. This cheese appears only in the dark, and resembles a triangular prism with several holes in it, similar to swiss cheese.
