After an intense and difficult struggle, Po manages to get the ghosts to turn on the Undertaker, except Shifu. Po then turns himself into a Jiang Shi to fight and defeat Shifu, and Tigress and Monkey manage to cure both of them by exposing them to the morning sunrise. in the end Po makes them all admit he was right because no one believed him.
