Gold Mouse

Gold Mice are apparitions of mice 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 with Speedy Spirits, if Luigi fails to catch a Gold Mouse, he is given other opportunities to do so, such as re-scanning a piece of cheese after exiting and re-entering a room.

Locations
This is a list of the locations of each Gold Mouse in the game and the rewards earned for capturing them.

Without cheese
Some of the Mice, though, are found in rooms (or hallways) without any cheese. When the player enters some specific rooms, there is a 20% chance of a Gold Mouse to appear.

Trivia

 * The Tea Room is the only room which contains two Gold Mice: one found by checking a piece of cheese, while the other is found randomly.
 * Whereas all Speedy Spirits give Luigi 20 Coins, all Gold Mice give him 30 Coins.
