Emerald Star

The Emerald Star is the second of the Crystal Stars Mario collects in Paper Mario: The Thousand-Year Door, obtained upon completing Chapter 2: The Great Boggly Tree.

According to the legend of the Crystal Stars as told by Grifty, the Emerald Star was given to the Punies to guard as a favor of the Goomba hero for saving them from monsters. The Goomba hollowed out a large tree for the Punies to make their home in, where the Emerald Star has since been guarded. During Mario's adventure, the X-Nauts took over The Great Tree in search for the Emerald Star and captured many of the Punies living inside. As Mario rescued the Punies, he discovered the location of the Emerald Star in the tree's basement. However, the leader of the X-Naut team, Lord Crump, quickly stole the Emerald Star once it was revealed. In an effort to keep the Emerald Star to himself, Lord Crump activated a time bomb while he made his way to the entrance, only to be stopped by the Puni elder, allowing Team Mario to catch up with him. Crump then deactivated the system and fought Team Mario in the Magnus von Grapple suit. Upon recovering the Emerald Star, the Puni elder allowed Mario to have it for the time being, and the star teaches Mario the move Clock Out to use in battle.

During the final battle with the Shadow Queen, when the Crystal Stars spread out to the locations as to where they were found, the Star returns to the Great Tree, where the Punies are alerted to Mario and his team facing their darkest hour and cheer them on before the final round.
