Blue Mice are the ghosts of mice found in Luigi's Mansion. They run along the floors of most of the hallways and deal five HP of damage if Luigi touches them. They are very common and have no HP value; they are simply sucked up instantly, similar to Bats. They can also be defeated instantly via any element.
The Blue Mice are usually found in the dark halls and occasionally hidden places. However, in the PAL Hidden Mansion, they are often located in normal dark rooms as well.
