In the story, Simba the lion's father was killed by a hunter. From then on, he and his two younger brothers (first younger brother, then younger sister ...) were adopted and raised by mother wolf. They also met Baksa, a deer, a chubby mouse who had been looking for treasure, Troy, a watchdog in the city (later renamed Na Wei), and a canary who always wanted to sing. In the forest, Xiong Balu, Snake King Card, Basila the Leopard and Professor Augustine the learned owl taught them all kinds of skills and survival skills, with the aim of fighting Shirley the tiger and his minions and regaining the throne. In addition, in order to make Simba and Baksa the kings of the jungle and forest, the firefly queen and the tree king Yabo gave them the sacred power of the Big Dipper, respectively. The chubby mouse also got two icons from the ancient Egyptian mouse king during its growth and adventure. The thin man's icon can see everything that happens now and in the future, while the fat man's icon can conjure up anything he wants. Simba grew up in this story and eventually became the king of beasts.
