Emerald Star

The Emerald Star is the second Crystal Star and was found in The Great Tree in Paper Mario: The Thousand-Year Door. It was stolen by Lord Crump, but given to Mario by the Puni Elder after driving the X-Nauts out of the tree. This Crystal Star will teach Mario the move Clock Out, which costs 2 SP. To use this move, you must repeatedly press the button that appears on the opponents side of the field. If done correctly, enemies will be immobilized for a few turns. Be careful! The buttons will change at random intervals, and you may end up freezing yourself!
