Crystal Star

The Crystal Star is the seventh and final of the Crystal Stars Mario collects in Paper Mario: The Thousand-Year Door. Originally, the Crystal Star was kept hidden in Rogueport, but Grodus and the X-Nauts found it and took it to their fortress on the moon. After reaching the moon through Grande Boom in Fahr Outpost, then navigating the X-Naut Fortress, Mario and his partners have to fight Lord Crump in the Magnus von Grapple 2.0 mech suit to recover the stolen Crystal Star. The Crystal Star teaches Mario the move Supernova upon collecting it.

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 does not return to where it was originally found. It instead retreats to Fahr Outpost, alerting the mayor of the crisis Mario and his team were facing, at which point he assembles the Bob-ombs that operated the cannon as a cheering section for the heroes, just before they defeat the evil queen once and for all.

Trivia

 * Despite the fact that it was originally in Rogueport, it appears in Fahr Outpost during the battle with the Shadow Queen.
