Bunker

The Bunker is Professor E. Gadd's shelter from the hostile ghosts on the Nintendo 3DS game Luigi's Mansion: Dark Moon. It is also where E. Gadd pixelates Luigi from the plumber's home, and all mansions in the game. This is apparently the only place where ghosts can't enter. Here, E. Gadd and Luigi can search the Dark Moon pieces, and repair key objects that were broken.
