Mice are a type of ghost in Luigi's Mansion and its Nintendo 3DS version.
Description[]
Mice are the ghost counterpart of living mice, in a similar manner to how Bats are the ghost variation of their living counterpart. Mice have purple, blue, and gold varieties, none of which are the colors of any living mice. All Mice have yellow eyes and, like living mice, also have two big ears, a nose, and a tail. However, every ghost Mouse does not have any legs or feet.
Blue Mice slowly move along the ground, something that can also be done by Purple Mice, except they can also travel up walls, unlike living mice. Gold Mice emerge from either a block of cheese, if scanned by the Game Boy Horror, or from the wall in certain rooms at random, and when a Gold Mouse emerges, it quickly speeds over to the other side. None of the Mice have any HP, meaning Luigi can effortlessly vacuum them into the Poltergust 3000.
