This is the story of a little penguin named Mumble who has a terrible singing voice and later discovers he has no Heartsong. However* Mumble has an astute talent for something that none of the penguins had ever seen before: tap dancing. Though Mumble's mom* Norma Jean* thinks this little habit is cute* his dad* Memphis* says it \just ain't penguin.\ Besides* they both know that* without a Heartsong* Mumble may never find true love. As fate would have it* his one friend* Gloria* happens to be the best singer around. Mumble and Gloria have a connection from the moment they hatch* but she struggles with his strange \hippity- hoppity\ ways. Mumble is just too different--especially for Noah the Elder* the stern leader of Emperor Land* who ultimately casts him out of the community. Away from home for the first time* Mumble meets a posse of decidedly un-Emperor-like penguins--the Adelie Amigos...
