Prince Mush

Prince Mush is the first champion of the Glitz Pit. He appears at the end of the third chapter in Paper Mario: The Thousand-Year Door. Prince Mush was captured and had his power drained by Grubba's power-sucking machine after he found out that Grubba was using a Crystal Star to drain fighter's powers. As such, Mush was missing for an extended amount of time. Afterward his older sister Jolene went undercover in the Glitz Pit to look for him, and after accidentally seeing Grubba power up by using his machine, she carefully guided Mario to defeat Grubba. After Grubba's defeat, he made it clear to Jolene that Mush was dead. The evil promoter had sucked the life out of Mush with his machine for his own selfish vanity, or so he had thought. Jolene is refrigerated with grief, as it is now confirmed what she long suspected to be true; her little brother was no more. Subsequently, Mush appeared out of the Gold Star, which powered Grubba's machine. It turned out he was not dead after all; perhaps the goodness of the Crystal Star had kept him alive. Now united with his sister Jolene, they rejoice.

Later in Mario's adventure, he gets an e-mail from Jolene saying that Prince Mush was planning on making a comeback.
