"Happy Feet" is set in an Emperor Penguin colony, where each penguin must sing a song called a "Heartsong" to find a mate. Two penguins, Norma Jean and Memphis, are attracted to each other by their songs, and they start a family. While Norma Jean is fishing in the ocean, Memphis is left with the egg, and he accidentally drops it on the ice, exposing it to the cold temperatures of the Antarctic. The young penguin chick who hatches out of this egg has a terrible singing voice and later discovers he has no "Heartsong." However, he does have a talent for tap dancing.
