Secret Mine

The Secret Mine is the forth Mansion that Luigi goes to in Luigi's Mansion: Dark Moon. This mansion is located on a snowy mountain, which causes the mansion to be frozen over, inside and out. Also, as the name implies, the mansion was built near a now abandoned mining area, which Luigi will explore part of. Professor E. Gadd sends Luigi to the Chalet where a group of Toads were studying the ghosts. When Luigi finds a Blue Toad he does a little dance causing the ice under their feet to break and they drop into a cave. The Chalet is built just above an abandoned mine that Luigi will need to explore.
