Elijah Wood and Robin Williams are in negotiations to reprise their penguin alter egos in Happy Feet 2, the follow-up to the 2006 computer animated musical about a young tap-dancing social outcast named Mumble amongst a society of uncannily talented singing penguins. But under the tutelage of some funky fresh penguins including Ramon and the master of funk Lovelace (both voiced by Williams) Mumble gets the courage to be true to himself and his happy feet.

The sequel's story is being kept under wraps but George Miller is writing and directing again.
