Into the world of the Emperor Penguins, who find their soul mates through song, a penguin is born who cannot sing. But he can tap dance something fierce!

Mumble the penguin has a problem: his son Erik, who is reluctant to dance, encounters the Mighty Sven — a penguin who can fly! Things get worse for Mumble when the world is shaken by powerful forces, causing him to bring together the penguin nations and their allies to set things right.
