Son of Memphis (Hugh Jackman) and Norma Jean (Nicole Kidman), Mumble (Elijah Wood), a sweet little ball of penguin fluff has one big problem: no matter how hard he tries, he can’t sing a single note. In a world where every penguin attracts their soul mate through their own special heart-song, he cannot ever truly belong. But as it happens, Mumble is a brilliant tap-dancer! When he unleashes his deepest feelings, they don’t come from his beak…they pour out through his “happy feet.”

As he grows into a teenager who is keen to gain acceptance, he fails to graduate and is the last to lose his adolescent feathers…setting him further apart. But Mumble is curious about the world and not afraid of challenges thrown in his path.

And when the seas become depleted of fish, the Elders of the Penguin Nation blame Mumble and his strange ‘hippity-hoppity’ gait for disturbing the natural order. So he sets out on a journey across the vast Antarctic landscape to prove them wrong.
