石器時代：尋找傳說中的寵物

The story begins with the meeting of the trainer "Wudi" and his pet "Moka," as they embark on an adventure together. Along the way, they fend off villains, make new friends, and capture various pets across the continent of Nise. In the anime, viewers get a glimpse into the lesser-known sides of the pets from "Stone Age M," such as how Wudi accidentally discovers the secret behind Moka's fire-breathing skill, how "Qibao" and "Gerdun" meet Wudi and Moka, and many more amusing stories from their journey, including moments where Moka finds himself in embarrassing situations.
