Happy Feet 2 Trailer

Happy Feet 2 – Let’s shake this world!

Happy Feet 2 – He looks like a rainbow!
Mumble, The Master of Tap, has a problem because his tiny son, Erik, is choreo-phobic. Reluctant to dance, Erik runs away and encounters The Mighty Sven—a penguin who can fly! Mumble has no hope of competing with this charismatic new role model.
But things get worse when the world is shaken by powerful forces.
Erik learns of his father’s “guts and grit” as Mumble brings together the penguin nations and all manner of fabulous creatures—from tiny Krill to giant Elephant Seals—to put things right.
