He is mostly concerned more about the show's ratings and reception and is very money-oriented.

Yoshi is a pirate as was shown in the episode Ship of Fools. In The Bracemaster, he was Dr. Katashi's assistant, was a dentist, and a member of the Onis in The Oni Express. In The Wizard of Ozu, he plays the part of the Tinman, but the rest of the cast ignores him and he is thus left rusting in the rain. In "Fashion Frenzy" when Lily is talking about her favorite designer making 3-legged pants, Yoshi reveals to the cast that he has 3 legs, but this has only been mentioned in this episode.

Little sushi-beings that serve as scene transitions or bumpers. They dance around and make cute noises.
