Cool, Cool Mountain is the fourth level in Super Mario 64. The course is a snowy mountain, which features slippery hills and wooden structures like bridges and a cabin. Inside the cabin is a sub-area which contains a large ice-made slide leading to the other cabin on the bottom of the level. This is one of the two snow-themed levels in the game, along with Snowman's Land.

Cold, Cold Crevasse
Cold, Cold Crevasse is a supposed place on Cool, Cool Mountain as it is mentioned on the retail version of the game. It is written about it on a sign behind Mario at the start of the level, before the broken bridge, which reads as "Danger! Cold, Cold Crevasse Below!". Other sign with this same message appears after the normal bridge and before the other broken bridge near to the Red Coins Star generator.
