Cool, Cool Mountain

Cool, Cool Mountain is the fourth course of Super Mario 64 and Super Mario 64 DS. The entrance to the level is behind the door to the left of the first floor of Princess Peach's Castle, near the room with the entrance to Bob-omb Battlefield. Three Power Stars are needed to unlock this door and the center painting will take the player to Cool, Cool Mountain, with the other two simply being decoration.

Layout
The player starts off on the top of the mountain next to a cottage. The cottage chimney contains an entrance to a winding Slide with many Coins and will also have a large penguin to race against from the third mission onward. Above the cottage is a small Penguin and behind the cottage is a platform with a Spindrift, as well as a snowball for completing the fifth mission. To the right of the starting area is a broken bridge that will teleport the player character to the bottom of the mountain, and to the left is a large slide that winds to about halfway down the mountain.

At the bottom of the slide is the Headless Snowman along with a couple of Spindrifts below a ledge. The large bridge nearby contains two jumping Mr. Blizzards that the player must avoid to make it across. Beyond this bridge is a broken bridge that leads to the course's Star Marker and a series of ramps that lead to the bottom-most portion of the mountain.

Both the ramp and the aforementioned broken bridge warp bring the player to roughly the same spot at the bottom of the mountain. To the left is an empty snowfield with a Red Coin at the end in the original game, though the DS version also has a trio of Goombas that wear the character's caps in this area. To the right is the Mother Penguin Tuxie belongs to as well as the end of the cottage's slide, which is a one-way exit. The gondola further to the right will bring the player character to the area with the Headless Snowman, though a floating platform with a Bob-omb Buddy (and the Star Switch in the DS version) is in the center off to the side of the gondola's path. Near the gondola's starting position is a cannon that can fire the player character to an area beyond a large gap. This area has a couple of Spindrifts on a narrow ledge along with a large cave that Mario has to Wall Jump up to reach the sixth Power Star.

Trivia

 * In the Super Mario 64 DS version, it is possible to get 255 coins (the maximum number of coins allowed) by entering the cabin again and again and defeating the Goombas with caps and/or destroying the bricks (next to the bodiless snowman). This is also true in Snowman's Land, by entering and exiting the igloo.
 * This is the only course in the game other than Bob-omb Battlefield to have more than one cannon.
 * The music that is played here (as well as the music for Snowman's Land) is a Christmas-themed iteration of the cover of The Princess's Secret Slide's music. A remix of the music also appears as the music for the Dream Snowball Fight event in Mario & Sonic at the Olympic Winter Games (Wii version).
 * In the Super Mario Mash-Up Pack in Minecraft: Wii U Edition and Minecraft: Nintendo Switch Edition, one of the paintings that can be hung on a wall is the Cool, Cool Mountain painting.
