Behold, the first trailer for "Happy Feet 2," the sequel to the 2006 Best Animated Feature Oscar winner that taught the world to live, love and have a healthy fear of global warming again.

This time around, penguin tap-master Mumble and his dance-a-phobe tyke Erik must unite all arctic creatures again to combat more forces that threaten their polar environment.

This second go-round will star Elijah Wood, Pink, Elizabeth Dailey, Sofia Vergara, Robin Williams, Brad Pitt, Matt Damon and Hank Azaria, and opens "Novemburr" 18, 2011.
