Spin

Star Spin is a move that Mario can do in Super Mario Galaxy. It is done with the Wii Remote when the player shakes it around the screen. The move is slightly like a Spin Jump on ground. It can be used to hit objects thrown at Mario to launch them back, it can be used to activate Boost Stars, even pummel enemies and dig up coins.

A very useful technique of the Star Spin is the ability to stun/freeze enemies by whipping the Star Cursor at them. This gives Mario a chance to run away or attack the enemies if the Player is fast enough.
