Prince Croacus

Prince Croacus is a deceased (euphemistically referred to as "wilted") prince of the Floro Sapiens in Super Paper Mario. He was Queen Croacus the Second's sibling, and was going to inherit the throne. However, he suddenly wilted in the year 444, which not only caused his death, but that of his father as well. Queen Croacus the Second took the throne in his place.

Trivia
