Question: What type of penguin is Mumble? Title: Happy Feet Movie plot: 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.
