Sapphire Star

"Huh?!?! You want this, amigo? This little rock over here? Are you serious? Well, that's no big deal... Here, take it. What do I need one or two extra gems for? I did not really like that one, anyway."

- Cortez

The Sapphire Star is the fifth of the Crystal Stars Mario collects in Paper Mario: The Thousand-Year Door, obtained after finishing Chapter 5: The Key to Pirates.

According to the legend of the Crystal Stars as told by Grifty, the Sapphire Star was brought to Keelhaul Key by the tired Koopa hero in an effort to keep it safe. However, the pirate Cortez stole the star from him easily and added it to his treasure hoard. After being shipwrecked on Keelhaul Key and navigating Pirate's Grotto, Mario encounters Cortez and battles him for the Sapphire Star. After the battle, Cortez gives it up willingly, stating he didn't even like it nor need it. The Sapphire Star teaches Mario the move Sweet Feast to use in battles.

During the final battle with the Shadow Queen, when the Crystal Stars spread out to the locations in which they were found, the Sapphire Star returns to Keelhaul Key, where Pa-Patch and the rest of the shipwrecked crew lend their support to Mario and his team just before the final round.
