The story

Tottoko Hamutaro Hai! is the sequel to Tottoko Hamutaro, or in English, Hamtaro. The series revolves around the 15 original Ham-Hams in short 5-minute episodes. The Hai! series is animated differently from the original series, most notably, the head-to-body ratio is off, and it is also computer-generated in 3-D. (Source: Wikipedia)
