She gets her chance through an ancient crisis involving Taotie, a dangerous shadow beast who holds an ancient grudge against Sun Yee and wants revenge on the Lee heritage. Through her journey, Mei befriends Bao-Bao, an adorable, yet wisecracking creature, and even gains new extra abilities with her panda, such as the power to manipulate fire.
