Cool, Cool Mountain

Cool Cool Mountain is the third painting world in Super Mario 64. It is the home of several Penguins and Mr. Blizzard's. Mario starts out at the summit unlike Tall Tall Mountain and must progress down the icy slopes all around the mountain. At the summit is a house with an oversized chimney that Mario can enter. Inside is a penguin that will race Mario on a huge ice slide. Also at the top is the penguin Tuxie, which Mario must take to his mother at the bottom.

After Mario defeats Bowser, he can go and race the penguin again, except now he's massive and harder. There is no reward for winning the race.
