Synopsis

Mumble is a tone-deaf Emperor Penguin who is unable to sing his "heart song," the ritual required to win a mate. The fact that Mumble is a terrific tap dancer is completely lost on his tribe, and he spends a rather lonely adolescence as an outsider. His hero's journey involves both discovering his own innate coolness, and, more importantly, solving the mystery of the dwindling supply of edible fish in the ocean.
