Boulder Bowl Galaxy

Boulder Bowl Galaxy is a new galaxy set to appear in Super Mario Galaxy 2 for the Wii. At the moment, not much information is known about it. The galaxy features the prominent use of the Rock Mushroom that turns Mario into a solid boulder. Some planets included in the galaxy are made of rocks and soil and steel platforms. Bowling pin-like enemies are found in the galaxy, which the plumber can bowl over by rolling into them in his boulder form.

The galaxy also features an armadillo-like boss named Rollodillo that Mario must defeat using the Rock Mushroom.
