Happy Feet 2 - Happy Feet Movie Sequel

There's a movie sequel to Happy Feet ahead of us! Elijah Wood and Robin Williams will reprise lend their voices again to the characters Mumble, Ramon, and Lovelace. The voice cast also includes Robin Williams, Hank Azaria, Matt Damon and Brad Pitt. Happy Feet 2 will be directed by George Miller the co-director of the first film. The film will be released on November 18, 2011.

Plot details of Happy Feet 2 should emerge online soon. But we already know that Happy Feet 2 will be done in 3D. So we may expect Mumble's crazy dances to be even more impressive than before!

I wonder what songs we're going to hear in the movie Happy Feet 2... Any suggestion?
