Emperor penguins are born to sing. All except young Mumble, who was born to dance... tap dance. Such un-penguin-like behavior eventually gets Mumble kicked out of Emperor Land and into the big, cold world. Joined by his Adelie Amigos and an all-knowing Rockhopper penguin named Lovelace, Mumble embarks on an epic journey and ultimately proves that by being true to yourself, you can make all the difference in the world!
