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. Unlike the Drip Drop Galaxy, this galaxy has a large, spiky, shell shielding most of it. This galaxy is the home of Kingfin, who Mario must defeat to earn a Power Star.
Planets/Areas
