Big Grey (voiced by JB Blanco JB Blanc) is a wolf, handsome and conceited, dreaming of being the leader of the pack. Lao Ji is a strong opponent of Big Grey, competing with Big Grey for the position of Wolf King, they decided to fight it out. On the eve of the fight, Big Grey had magic in his heart and turned into a sheep. He had to leave the wolves and live with the sheep. Lao Ji took advantage of the old wolf king's surprise and pushed him off the cliff to win the wolf king's throne. A lamb sneaked into the northern meadow and was caught by wolves and rescued by big ash. This behavior infuriated Lao Ji, who decided to attack the sheep. When he learned that the wolves were going to attack the sheep, Big Ash decided to lead the sheep to fight against the wolves. While building the defense line, Big Ash was found to have something to do with the wolves and lost everyone's trust in him. He had to leave the sheep alone, and on the way he had a chance to turn back into a wolf, but at the same time, knowing that the wolves were about to attack the sheep, he gave up the chance to become a wolf and resolutely returned to the sheep and led the sheep to defeat the wolves. The two communities finally reached a peace agreement.
