Diggsbee Digglesworth is the foreman and head miner of the Dream Crystal Mines at the base of the Mystical Mountains.  He was originally a Dream Maker, but he loved to dig so much, that all of the dreams he made involved digging, so he was reassigned to the Dream Crystal mines.  His claim to fame is being the one who found the giant Dream Crystal, which powers most of Dreamland and now resides in a vault in Dreamland Castle.
