Billotchi was present in the 15th Anniversary Character Poll as a male adult candidate.
Billotchi's appearance is of a penguin-like Tamagotchi, with dark gray skin, dark gray-brown feet, a white belly and a large, pink bill. His bill was a pastel pink in his original artwork, but was later might a much brighter shade of pink. His body is a much lighter shade of gray in the 15th Anniversary character poll.
His favorite hobby is whale-watching. If he's going to date someone, he's already decided that it'll have to be a nice girl who'll go whale-watching with him.
