Beware of Bouldergeist

Beware of Bouldergeist is the third level of Ghostly Galaxy in Super Mario Galaxy. In this level, Mario faces off a large rocky ghost boss called Bouldergeist, and Mario needs to defeat it to earn a Power Star.

Layout
A member of the Toad Brigade informs Mario that the monster that kidnapped Luigi in Luigi and the Haunted Mansion lives here. Mario has to find his way to a circular stone platform where he meets Bouldergeist, a ghost with the ability to control stone. Mario must dodge the rocks it uses and its hands in the second round meanwhile grabbing the Bomb Boos and hitting its body. Mario must defeat Bouldergeist by using Bomb Boos to hit its main body three times, twice (a total of six times). Doing so causes Bouldergeist to explode, leaving behind a Power Star.
