This is Hoho, one of the minor roles. Hoho is a strange bird that makes his nest near Ta-Toon-Da Castle. In the Japanese versions, all of his voice samples are pronounced by a "Ho Ho", while the English versions have him saying "Mm-hm". His lines in Fever imply that he is just one of an entire species. The Hoho Bird that we follow seems to believe himself a super-cool superhero.

This role is meant to replicate the voice here
