Kung Fu Panda 2 3D 2011

As of my last knowledge update in September 2021, there hasn't been an official movie titled "Kung Fu 2" released. If this is a movie that came out after that date, I wouldn't have information about its plot. It's possible that there might be a movie by that title in development or released after my last update. Please provide more context or details if you have specific information about the movie you're referring to.
