*SLIGHT SPOILER ALERT*
After you've beaten the game you get treated to a still of Po and all his friends doing a cool Kung Fu Pose. This is to be expected given the nature of the content. What is surprising, however, is what Po is wearing. It's a yellow outfit with black trim, a straw hat and he's wielding a quarter staff. This is an outfit which bears quite the resemblance to the Cardboard Tube Samurai of Penny Arcade fame. Coincidence? Probably not.
