Yam Roll (or the long title, The Very Good Adventures of Yam Roll in Happy Kingdom) is a Canadian animated television series created by Jono Howard and Jon Izen for CBC Television. Produced by March Entertainment, the series premiered on February 6, 2006, airing on Saturday at 10:00am and 10:17am on local CBC channels.
Yam Roll features a cast of animated sushi characters, and other anthropomorphic instances of Japanese cuisine, all living in Happy Kingdom, a prosperous city which is upset quite often by monsters.
Quoting from March Entertainment's site:
Yam Roll tells the story of an exotic land of sushi and how one of its inhabitants, a super-powered cab driver named Yam Roll, braves monsters and bad guys all in the name of unrequited love. Despite being well liked in Happy Kingdom due to his good nature and sweet, root-vegetable flavouring, Yam Roll is still a frustrated guy. Why? Because he is hopelessly in love with the town sweetheart, a spicy tuna roll named Minamiko.[1]
With the help of his wise Zen master, Katcho Miso (an old lump of salty bean paste), his sidekick and best friend Ebi-san (a severely hyperactive shrimp), and the rest of his motley maritime crew, Yam Roll's life is always an exciting ride.
Yam Roll also hosts a large variety of other sushi characters, including Yam Roll's friends, enemies, and random passers-by. Each character is wittingly named after their sushi names (e.g., Ebi, which means "shrimp" in Japanese).
