Domo is a strange creature that hatched from an egg. His 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 via producing a low-pitched noise which sounds somewhat like his own name, but other characters appear to understand him.

The Domo brand is hugely popular around the world and can be found in every format from plush and vinyl toys to clothing and mugs.
