Crystal Quarry

The Crystal Quarry is a room in the Secret Mine in Luigi's Mansion: Dark Moon. This room is in B3 of the Secret Mine. Upon enetering this room, Luigi will find three Boos and an imprisoned Sneaker, Slammer and Greenie. After this, when Luigi checks on one of the crystals, the ghost will pop out at Luigi after around 4 seconds of waiting, the ghost will make Luigi fall back, then the ghost will break out of their crystal and proceed to fight Luigi. After the first ghost has been defeated, the other two will come in, and this time Luigi must fight these two ghosts at the same time. The Crystal Quarry was set up by Boos to increase the powers of every ghost. Three ghosts have to be fought in the Crystal Quarry; they are a Strong Sneaker, a Strong Slammer, and a Strong Greenie. After fighting these ghosts, Professor E. Gadd will call Luigi on the Dual Scream and tell him that even he does not know what those crystals were, that the three Boos fled, and that somehow they have been controlling the ghosts to get in the crystals.
