Spin

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

Mario is able to do a Star Spin due to a White Luma that Princess Rosalina gives Mario. Also, whenever Mario does a Star Spin, the white Luma pops out of his hat for a second. Interestingly whenever Mario does a Star Spin, all nearby Luma react to it.

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.
