Ever felt like you don't quite fit in? Meet Mumble, the penguin who needs to find his heart song in order to find his true love. The problem is Mumble cant sing, but has an extraordinary talent for tap dancing. Mumble is just too different-especially for the stern leader of Emperor Land, casts him out of the community. Away from home for the first time, Mumble meets a posse of un-Emperor-like penguins- the Adelie Amigos. Together they set out across vast landscapes and, after some epic encounters, proves that by being true to yourself, you can make all the difference in the world.
