The first trailer has landed for Happy Feet 2, the sequel to 2007's best animated feature Oscar winner, and it has to be said, it is pretty grin inducing.  As to be expected, it features a host of cute and cuddly penguins bopping about and tapping their (happy) feet, and in this case rapping to Justin Timberlake's "Sexy Back", albeit cunningly reworded "Fluffy Back" - think of the children!  Happy Feet 2 carries some heavy weight vocal talent, including Elijah Wood, Robin Williams, Hank Azaria, Brad Pitt, Matt Damon and Sofia Vergara among a ton of others, and Mad Max's George Miller is returning to direct.  It opens November 18, 2011 in the US, followed by a later release of December 2, 2011 in the UK.  Hit the jump for the trailer and official synopsis.Here's the synopsis:

The sequel to the Academy Award®-winning animated smash hit, “Happy Feet 2″ returns audiences to the magnificent landscape of Antarctica, reuniting us with the world’s most famous tap-dancing penguin, Mumble (Elijah Wood), the love of his life, Gloria (Alecia Moore {Pink}) and their old friends Ramon and Lovelace (Robin Williams). Mumble and Gloria now have a son of their own, Erik (EG Daily), who is struggling to find his own particular talents in the Emperor Penguin world. But new dangers are threatening the penguin nation, and it’s going to take everyone working–and dancing–together to save them.
