Gold Mouse

Gold Mice are cowardly animal spooks found in the game Luigi's Mansion. They come out when Luigi examines one of five pieces of cheese with his Game Boy Horror and then scurry around the room before escaping through the wall. Gold Mice also randomly appear in five predetermined rooms or hallways 20% of the time Luigi enters the room or hallway, for a total of ten mice in all throughout the mansion. If Luigi manages to suck one up before it escapes, a large amount of money will spray from the nozzle of the Poltergust 3000, which can include valuable treasures like Stones. Unlike Speedy Spirits, if Luigi fails to catch the Gold Mouse, he can exit and reenter the room and scan the piece of cheese again.
