I'm not even sure if Richard worked on the show during season 23. I think he left the show after season 22 due to his illness. Ssetta says the bird who was on the Season Premire episode of Season 23 was performed by Richard Hunt, which sounds right. But that may have been the last thing he ever did on the show, because I really don't remember seeing Forgetful Jones, Don Music, Placido Flamingo, Gladys, or the Two Headed Monster in any episodes from Season 23. I think that's why they added all those new charachters that year. Rosita, Chicago the Lion, Roxy Marie, Baby Bear and Goldilocks, etc.
