Happy Feet

Every penguin sings a unique song called a "heartsong" to attract a mate. If the female likes the male and his song, and if it completes the female's song, the two penguins mate. A penguin named Norma Jean sings the song "Kiss", whereupon a male penguin named Memphis sings "Heartbreak Hotel". Norma Jean chooses him as her mate. They couple and Norma Jean lays an egg. The egg is left with Memphis while Norma Jean leaves with the other females to fish. While the males struggle through the harsh winter, Memphis drops the egg, briefly exposing it to the freezing Antarctic temperatures. The resulting chick - the film's protagonist, Mumble (voiced by Elizabeth Daily) - has blue eyes, ever-lasting down feathers, and a terrible singing voice. However, Mumble has a talent that no other penguin has ever seen before: tap dancing. As a result, Mumble is ostracized, with only his mother and his best friend Gloria to turn to. One day Mumble wanders into a secluded area, where he is free to dance. Mumble is interrupted when Boss Skua and his posse Dino, Frankie, and Vinnie attempt to eat him. Mumble stalls by asking the leader of the pack about a yellow band that is attached to his right ankle. The Boss Skua tells Mumble that he had been abducted by "aliens". Mumble narrowly escapes the hungry birds by falling into a crevice. Mumble grows into an adult, still half-covered in fluffy down. Mumble's class graduates, and although he has not graduated, he joins them on their first trip into the ocean. His class ends their day by partying on an iceberg. Mumble constantly interrupts their singing and is forced to enjoy the party on a small iceberg. Mumble dozes off and wakes to find himself alone. A leopard seal chases him off the iceberg, and the penguin finds himself far from his home. He finds some Adelie Penguins, small in stature, but fiercely loyal to those they call friends. He befriends a small group of bachelors who form a club called "the Amigos": the leader, the brothers Raul and Nestor, and twin brothers Rinaldo and Lombardo. The Amigos quickly embrace Mumble's dance moves and assimilate him into their misfit group. Mumble's joy is cut short when he accidentally starts an avalanche and causes a hidden human excavator to tumble out from a glacier. Driven by curiosity, he sets out to find the "aliens" responsible for the machine. In Mumble's old home, it is mating season, and Gloria (voiced by Brittany Murphy) is the center of attention. Although she is surrounded by a large horde of suitors, none of their heartsongs interest her. Ramon tries to help Mumble by singing a Spanish version of "My Way". Gloria isn't fooled, however, for she knows Mumble can't sing. She notices Ramon behind Mumble and shoves him away to reveal the little penguin. Gloria becomes angry and turns her back on Mumble. As Mumble has no heartsong, Gloria continues towards the other males visibly distraught. As a last resort, Mumble tries to persuade her to sing along to his tapping rhythm. Because of her affection for him, she complies. As Mumble's beat speeds up, Gloria finds the chorus to her heartsong, and realizes it is "Boogie Wonderland". Overcome with happiness that they can now be mates, the pair begin dancing, along with the other penguins. Noah the elder sees their lack of fish as punishment from the Great 'Guin for Mumble's dancing. Mumble tries to explain about the mysterious "aliens", and that they are the cause of the scarceness of fish, but only his mother and Gloria believe him. Noah exiles Mumble from the colony. Mumble vows that he will find the real cause of the famine. He travels across vast territories with the Amigos and Lovelace, a Crested Penguin. Gloria tries to come but Mumble, fearing for her safety, drives her off by insulting her singing talents. Mumble sees a boat and swims after it, leaving his friends behind. He ends up in a penguin exhibit at a marine park named Marine World. He tries to communicate with the "aliens" that surround him. When his pleas fail, Mumble nearly succumbs to madness after three months of confinement. Mumble starts dancing, and soon a large crowd gathers around the exhibit. He is released back into the wild, now with more adult feathers and a tracking device strapped to his back. He leads the humans to his native colony. The other penguins are skeptical at first, but when Gloria notices the tracking device, they realize that the “aliens” exist. Now convinced, the penguins (along with the once-stubborn elders) dance alongside Mumble in hopes of getting the humans' attention. A research team arrives and film the penguins dancing. They bring this footage back to the human world, and a worldwide debate ensues. The world governments realize they are overfishing the Antarctic waters, and conclude that the penguins are trying to communicate that to them. Antarctic fishing is banned, and the fish population recovers. At this, the Emperor Penguins and the Amigos dance and celebrate their triumph. A dancing baby penguin seen at the end is implied to be the child of Mumble and Gloria. In the credits, the characters reunite to dance for the final number, "The Song of the Heart."
