Boulder Quarry (Japanese: きょだいがんせきぐんGiant Rock Area) is a dungeon only playable in Pokémon Mystery Dungeon: Explorers of Sky. It only appears in the Special Episode Here Comes Team Charm! The player will have to face six Lairon and an Aggron at the end due to Team Charm trespassing onto their territory. It has a total of 11 floors, with Boulder Quarry consisting of five floors, Deep Boulder Quarry of five floors and Boulder Quarry Clearing of one floor. There is a relay point between 5F in Boulder Quarry and 1F in Deep Boulder Quarry. After going through Boulder Quarry, Team Charm comes to a place where there are twopaths to take. The music is a remix of the music from Mt. Steel in the first game.
