Po and the Furious Five uncover the legend of three of kung fu's greatest heroes: Master Thundering Rhino, Master Storming Ox, and Master Croc. Po breaks into the Hall of Heroes with Tigress and Mantis to see the new exhibits, especially for the ones featuring Masters Thundering Rhino, Storming Ox and Croc. Once there, Po tells the story of how that trio began as small time street fighters until the villainous Wu Sisters escape with plans to conquer China. Against this threat, Master Oogway convinces the selfish trio to accompany him on a quest to stop the sisters. In the challenges that follow, those masters find that the grandiose promises of riches they heard are fading as they learn that there are things far more worthy to fight for.
