Pushu Pushu and Nyuu arrived on vacation at “Acorn Island,” a paradise-like island where summer and autumn blend together. Upon landing at the airport, Paruti, a taxi driver who looked just like Nyuu, welcomed them with lively music. Pushu Pushu got caught up in the lively rhythm, but in the excitement, one of his cheeks flew off somewhere. Boarding Paruti's pride-and-joy taxi, they set off on a journey to find the cheek. Along the way, they met unique companions like Taiyo-san, Hairy-na, the Fishy Brother, Kawa-chan, and Shina-ta-san, and discovered wonderful music.
