Bouldergeist

Bouldergeist is a ghost with the power to control rocks in the Ghostly Galaxy. He holds one of the Power Stars. His main attack is throwing rocks (up to six) at Mario, however, he can get arms and punch you and jut out a line of rocks. Grey rocks have nothing inside them. Black rocks have Bomb Booes. Golden rocks contain a coin.

Strategy
To damage Bouldergeist, Mario must use a Bomb Boo and hit the boss with it. After you hit the boss three times, the true form is revealed; a small black ghost. Hit the boss again with a Bomb Boo. Once you have done the process, you do the ame process again, but now he has arms. These can be blown up with Bomb Booes, but have no coorelation with him whatsoever. Do the same process one more time and you have beaten him. He is involved with a Daredevil Comet.
