'Happy Feet,' the 2006 animated film featuring singing and dancing penguins and a subtle environmental message, took in almost $400 million worldwide and won an Oscar for Best Animated Feature. Now the flightless fowl are back for 'Happy Feet 2.'

In the sequel's trailer, the story continues with Erik, the son of Mumble and Gloria, trying to find his uncoordinated footing among his more talented dancing brethren. Some familiar voices from the first film are back, such as Robin Williams and Elijah Wood, and the late Brittany Murphy is replaced by rock singer Pink.

George Miller, who directed the first installment, also returns for the sequel, which opens in both 2D and 3D this November.

Watch as the smallest of the penguin crew throws down to LL Cool J's 'Mama Said Knock You Out' and Justin Timberlake's 'SexyBack,' whose lyrics have been cleaned up for young ears.
