Storm Cellar

The Storm Cellar is a room in Luigi's Mansion: Dark Moon located in the Old Clockworks mansion. It is only accesible in mission C-2: Underground Expedition. One Gem can be found in the Storm Cellar.

Information
Once Luigi uses the Special Compass to activate a door on the ground in Clockworks Court, he falls through a chute that leads to the Storm Cellar. It has a door leading to the Canyon Hall. The Gem is located behind some curtains above the bed in the left corner. Once the room is cleared of ghosts, Luigi must pick up the rock a ghost was holding and drop it in a tray to raise the gate blocking the door.
