Big Penguin

"I know speed when I see it, yes siree -- I'm the world champion sledder, you know."

- Big Penguin

The Big Penguin, also known as the Penguin Champ or Champion Penguin, is a giant penguin appearing in Super Mario 64 and its remake, Super Mario 64 DS. He is a competitor character along with Koopa the Quick, and is only raced once in the game in Cool, Cool Mountain. He claims to be the world champion sledder, and seems to know Mario prior to the game's events, calling him "buddy".

Big Penguin is raced against in the third mission of Cool, Cool Mountain. He can be found inside the house at the top of the mountain. When Mario drops in through the chimney, Big Penguin will speak to Mario and challenge him to a race. If Mario accepts, he will have to race down the icy slide in the mountain and beat the penguin to the finish line. The penguin will give Mario a Power Star if beaten. However, if Mario takes a shortcut by jumping onto another section or if he takes the hidden shortcut the Big Penguin will accuse him of cheating and disqualify Mario. If raced again after obtaining all 120 Power Stars (150 in the remake), he is even bigger and can easily knock Mario off the slide. If he is beaten, the same thing happens when Mario first raced him.

An unrelated character also described as a "big penguin" appears in the course Snowman's Land.
