Co-Star Luma

The Co-Star Luma is an orange Luma that is the playable character for Player 2 in Super Mario Galaxy 2. The Co-Star Luma can grab enemies which freezes them, and can also spin to stun enemies while holding them. The Co-Star Luma can also grab coins, Star Bits, 1-UP mushrooms, and air bubbles (when underwater), and then bring them to Mario. The Co-Star Luma can activate switches, make enemies do an action when grabbing them (For example, grabbing a Spiky Plant makes it retract its spikes.), and spinning characters and Lumas. If Player 2 is not playing the game, then the Co-Star Luma will appear onboard Starship Mario.
