Haibi (ビスカスちゃん, Bisukasu-chan) is a hamster who appears exclusively in the OVA, Ham-Hams Ahoy!. The Ham-Hams found Haibi after she fainted from exhaustion outside the Clubhouse. Hailing from the Flufferstuff Mountains, Haibi is on a mission to help find a special treasure for her grandma. She has a strong personality, but she is thoughtful and kind. She is also adventurous and can sing quite well.
- Her name in both Japanese and English comes from the Hibiscus genus of flowering plants. Additionally, she wears flowers that are reminiscent of a hibiscus's flower.
- Several pieces of Haibi merchandise were released (including a keychain figure), but all of them are rather rare. They seem to mostly originate from mail-in coupons from Shogakukan Learning Magazines.
