Flash

Flashes are elemental ghosts and a sub-species of the Purple Puncher. They are found in the game Luigi's Mansion. Flashes appeared in the Treasure Room and on the Roof. A block of ice protects the hearts of these ghouls. Luigi must melt these ice blocks by capturing a Fire Elemental Ghost and spewing fire at the ghost. Then the Flash's hearts will become vulnerable to the Poltergust 3000.
