Battlerock Galaxy

The Battlerock Galaxy is a galaxy in the Wii game Super Mario Galaxy. The galaxy contains a multitude of floating platforms and planet-sized rocks with a cannon-like object protruding from it. In some cases the main part of the galaxy will fire at Mario. Many robots and Bob-ombs appear in the galaxy. The inside of the Battlerock is unusually very mechanical and technological. The galaxy also contains an area where three Lumas are being held. Topmaniac is a boss here.
