This time, the stage is the "Cloud Kingdom," where everything is made of clouds! Clouds are precious—they invigorate flowers and plants, and create rain and rainbows. The Cloud Kingdom creates these clouds and travels around, delivering them to various towns and stars. There, a single cloud baby is born and, by chance, meets Baikinman and the others. Dokin-chan names it "Fuwary." As Fuwary grows up healthy and strong, its bond with Dokin-chan deepens. Meanwhile, a major crisis arises in the Cloud Kingdom: a mysterious stain is causing the clouds to lose their ability to fly! To make matters worse, Baikinman's invention "Baigumora," created so he can become the king of the Cloud Kingdom, goes completely out of control! Both the Cloud Kingdom and the Anpanman World are covered in dark clouds, plunging them into grave danger! Can Anpanman and his friends protect the Cloud Kingdom? And what will become of the friendship between Fuwary and Dokin-chan?
