Rio is a trumpet player. His species is unknown, although he sports many feline features and wears cheetah-print.
Despote his feminine appearance, Rio is actually male. Rio was formerly the most popular pop idol in the world, and he can't help but to act like a show-off. But once you get to know him better, he is actually an all-around good guy who's always chasing his dreams. To bring him the luck he needs, he continues to eat onion rings every morning.
