Happy Feet is a 2006 Australian-American computer-animated musical family film, directed, produced and co-written by George Miller. Happy Feet won the Academy Award for Best Animated Feature and the BAFTA Award for Best Animated Film, and was nominated for the Annie Award for Best Animated Feature and the Saturn Award for Best Animated Film. Every emperor penguin sings a unique song called a "heartsong" to attract a mate. If the male penguin's heartsong matches the female's song, the two penguins mate. Norma Jean, a female penguin, falls for Memphis, a male penguin and they become mates. They lay an egg, which is left in Memphis' care, while Norma Jean leaves with the other females to fish. While the males struggle through the harsh winter, Memphis briefly drops the egg. The resulting chick, Mumble, is unable to sing but can tap dance. Nevertheless, he is enamored with Gloria, a female penguin who is regarded as the most talented of his age.
