Happy Feet: The Videogame is an action-adventure video game based on the movie of the same name. The game was released on November 14, 2006 by A2M for the Wii, PlayStation 2, Nintendo GameCube, Nintendo DS, Game Boy Advance, and PC. Elijah Wood, Brittany Murphy, Dee Bradley Baker, Carlos Alazraqui, Jeff Garcia, and Johnny A. Sanchez all reprise their voice roles from the film.
The console versions (for PS2, Wii, GameCube and PC) feature 3 different modes: a dancing mode which simulates Dance Dance Revolution with the player pushing the button in response to arrows on the screen, a fishing mode in which the player collects pebbles and shrimp as well as air bubbles in order to breathe, and a belly-sledding mode where the player sleds and collects the number of fish needed, sleds to beat a given time or races another character down the hill. In the Nintendo DS version of the game, the rhythm sequences use gameplay mechanics similar to those in Elite Beat Agents, though greatly simplified.
The game also features each of these modes for two players. In the dancing and swimming games, the players compete with each other, while cooperating with each other in the multiplayer belly-sledding mode. Interestingly, the game features songs not in the film, such as "Shake Your Booty" from KC and the Sunshine Band for when Mumble hatches, and "I Will Survive" from Gloria Gaynor sung by Gloria when Mumble and her break up. These are for the dance modes of the game.
"Play as Mumble in the ultimate adventure to win the heart of Gloria and save the Emperor penguin nation. Based on Warner Bros. Pictures' upcoming comedy adventure HAPPY FEET, Midway's immersive video game puts the player in the "tap shoes" of Mumble, a young penguin born into a nation of Emperor penguins— where each needs a Heartsong to attract a soul mate. Unfortunately, Mumble is the worst singer in the world... however, as it happens, he is a brilliant tap dancer!"
