Bonefin Galaxy

The Bonefin Galaxy is a galaxy in Super Mario Galaxy. This galaxy, like the Drip Drop Galaxy, is basically a large body of water with a solid core. However, unlike the Drip Drop Galaxy, this galaxy has a large, spiky shell shielding most of it. This galaxy is home to Kingfin, a gigantic skeletal shark that Mario must defeat to earn a Power Star.

Starshroom
When Mario first enters the galaxy, he will start out on a green Starshroom near the Kingfin Planet. There are several Star Bits on its underside and a Launch Star on the top of it will take Mario to the Kingfin Planet.

Kingfin's Planet
When Mario lands on this planet, Kingfin will appear along with Skeletal Fish Guards and attack Mario. After Kingfin is defeated, the Power Star appears.

Mission
This galaxy contains only the following mission.
