Augustus John James "Jellypie" (a Wamplefloon), is pictured here.
Jellypie is about 7 years old, and one of the few of his species to reach adulthood safely. (They are prone to overinflation, resulting in a rather unfortunate end!)
Wamplefloon are an offshoot of the Gryphon species, about 14" high when seated.

Jellypie is a redbreasted Wamplefloon, as denoted by the four scarlet feathers on his wample.
