Happy Feet is a game that follows the story of Mumble, a young penguin born into a nation of singing emperor penguins. Each penguin needs a heart song to attract a soul mate, but Mumble is cursed with being the worst singer in the world. However, he has a talent for tap dancing.
The gameplay involves three main types: belly-sledding, where you control Mumble as he tries to beat his rivals; swimming, where you navigate through icy waters while avoiding predators; and dancing, where you help Mumble improve his footwork to impress his friends and family.
