Anpanman, his friends, and the cloud child Fuwari strive to save Cloud Country. In order for flowers and plants to be healthy, Cloud Country travels to distribute clouds that can make rain and rainbows to various towns and stars. A cloud baby born in Cloud Country runs across Baikinman and his friends. After meeting them, the baby gets the name Fuwari and quickly grows while developing a bond with Dokin-chan.
