Blue Mice are an enemy in Luigi's Mansion and its Nintendo 3DS version.

Profile[]

Physical description[]

Blue Mice are a type of Mouse ghost with a light-blue body.

Behavior[]

Blue Mice only travel along the floors in most of the hallways.

In Luigi's Mansion[]

Blue Mice, like their purple counterpart, are usually encountered in the hallways. If Luigi touches a Blue Mouse, he takes five HP of damage. Because Blue Mice lack any HP, they can be instantly vacuumed into the Poltergust 3000, like with Purple and Gold Mice as well. A Blue Mouse can be defeated instantly using any element.

In the PAL version's Hidden Mansion, Blue Mice frequently appear throughout the different rooms in general.
