History: Bouldergeist was happily living well enough alone, when suddenly Luigi was separated from the Toad Brigade and landed in his galaxy. Bouldergeist was not amused, and forced the Boo neighbors to lock him up in their mansion. Mario saved Luigi and eventually came back to fight him. Bouldergeist died (he didn’t re-die, as he was already a ghost), but was brought back to… un-life when the Daredevil Comet landed in the Ghostly Galaxy. Mario beat him again, now he’s just gone back to what he was doing.
