Cool, Cool Mountain

Cool, Cool Mountain is the fourth level in Super Mario 64. The course is a snowy mountain that 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.

It had been reported some cases of anomalies on Cool, Cool Mountain, mainly related to cut elements of the retail version of the game seen on early screenshots.

Cold, Cold Crevasse

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

The belief is that the player can reach Cold Cold Crevasse by falling at a specific spot.
