Xi Yangyang Yu Hui Tailang: Yang Nian Xi Yangyang

Pleasant Goat and Fatty Goat have grown up dreaming about the legendary dragon slayers of the Stone Age. Their chance to imitate those heroes goes spectacularly wrong when Fatty Goat accidentally switches bodies with Big Big Wolf and, together with Pleasant Goat, is thrown back into the distant past.

Stone Age Green Green Grassland soon faces a real dragon threat, leaving the misplaced trio with no easy way home and no choice but to face the legend they once admired from a safe distance. With a goat trapped in a wolf's body, a wolf trapped in a goat's, and old rivalries refusing to disappear, saving the past becomes as chaotic as it is dangerous.
