Penguins were given more prominent appearances in Super Mario 64, where they could be seen in the level Cool Cool Mountain. In the game, a Penguin lost her baby Tuxie and asks Mario to find her. Mario finds her and is awarded with a Power Star. Also, later, Mario has to race down a long, icy slide and get to the finish line before a Penguin does. If Mario wins, he will be awarded with another Power Star.
