Boss Enemy - Bouldergeist

The Bouldergeist will throw lots of boulders at you, including black boulders that turn into Bomb Boos and golden boulders that smash into golden coins to give you extra hp. He will also occasionally cause stalagmites to grow out of the ground, so watch out you’re not standing on those or you’ll take some damage!

You’ll need to grab the Bomb Boos and spin them into the Bouldergeist. Damage him three times and you’ll destroy his rocky exterior. When you damage his weak ghost body, you will trigger his next phase. In the next phase, he will create giant rock arms for himself. He will use them to punch and flatten you so watch out! You’ll need to spin Bomb Boos into his body to damage him permanently. If you spin them into his arms, they will be destroyed but only temporarily as he’ll recreate them and he won’t take permanent damage. Spin Bomb Boos at his body three times to reveal his ghost form and then throw a final Bomb Boo at him to defeat him for good and grab the Power Star!
