it's domo

Domo, the main character, is described as "a strange creature that hatched from an egg,with a large, sawtoothed mouth that is locked wide open. Domo's favorite food is Japanese-style meat and potato stew, and he has a strong dislike for apples, because of an unexplained mystery in his DNA. Domo can only communicate by producing a low-pitched noise which sounds somewhat like his own name, but other characters appear to understand him. Domo is known to pass gas repeatedly when nervous or upset.A Tokyopop press release of the Domo comic book states that "he communicates sotto voce with a verve that only his friends can understand." Clint Bickham, the writer of the Domo comic book, said that to him Domo's expression is "a sort of cheery wonderment. Like when a kid wakes to a room full of presents on Christmas day." While Domo's face has variants, to Bickham most of his expressions have "an underlying sense of fascination."

Domo lives in an underground cave with Mr. Usaji,known in Japanese-language versions as Usajii, a portmanteau of the words usagi, (rabbit), and jii  (old man, grandpa). Mr. Usaji is a wise old rabbit who has lived in a cave for decades, loves to watch television and drink astringent green tea. Mr. Usaji is not into any "new" materials, and does not own a telephone.In terms of fashion, Mr. Usaji focuses on materials instead of shapes. Mr. Usaji's favorite food is carrots, and his least favorite food is "something that is meaningless."
