Snowman's Land

Snowman's Land is the tenth course in Super Mario 64 and its remake Super Mario 64 DS. It is the second snow-based level in the game. The name of this world is a pun on "no man's land".

To access this course, Mario (or Luigi, Yoshi, or Wario in the DS version) will have to acquire the second of the castle's keys, and go to the floor directly above the lobby. Inside the mirror room, there will be a blank wall to Mario's left but if he were to look at the wall as it appears in the mirror, it will show the picture from the level Cool, Cool Mountain Mario should jump inside, and he will reach Snowman's Land.

In the DS version, there is a Wario painting behind the mirror; to get to it the player must use Luigi, for when he enters the room, power flowers will appear. Also, the door behind the mirror leads to a secret Power Star. It is also possible to grab infinite coins, as going in and out of the igloo creates more enemies inside the igloo all over again.

Levels
The level titles and numbers correspond to Super Mario 64 unless otherwise noted.

Star 1: Snowman's Big Head
In the first mission, Mario has to climb the giant Mr. Blizzard. When Mario reaches the ice bridge, the large snowman comes to life and says that something's (Mario's) climbing is bothering him (wondering if it is a snow ant or an ice flea). He then start blowing out of his mouth to try and blow the "pest" away. Mario will be blown off the ice bridge if he steps in front of the continuous breeze and also lose his hat. The way to get past is to use the penguin walking back and forth on the bridge to block the wind. The penguin, however, walks across, then stops and even walks back a few steps on its way across. Mario can also activate the cannons and carefully shoot up so he lands on the far left side of the ice in front of the snowman's head. Once the player reaches the other side, the player should continue climbing the mountain, and Mario will reach the Power Star.

In the Nintendo 64 version, Mario can ride on the penguin's head to avoid the wind. However, this isn't possible in the DS version. However, in the DS version, Luigi can perform a backward somersault to spin in midair, and float to the other end of the road, while avoiding the wind.

Star 2: Chill With the Bully
In this mission, Mario must travel and find a Chill Bully walking on an ice platform above a pool of extremely cold water. Mario must defeat the bully by knocking it off the small stage and into the water (identically to how he defeats Bullies in Lethal Lava Land). Once the player has defeated it, a Power Star will appear in the middle of the platform.

On a side note, falling into this water is equivalent to falling into lava, which will take away three health points from Mario.

Star 3: In the Deep Freeze
Once entering the course, Mario should take a look to his left. He will see an ice structure. Inside, he will also see a Power Star. The player should inspect the sculpture and find a way in. After navigating through it, Mario will finally reach the star.

On DS, the mission has been titled "Yoshi's Ice Sculpture", and instead of going in a maze, there will be Ice Cubes and Yoshi using his power flower will have to destroy the Cube with the power star in it.

Star 3 (DS): Yoshi's Ice Sculpture
For this star, Yoshi is needed. The player must go left from the start where they will see an ice sculpture of cubes. They need to use Yoshi's Power Flower to melt the Ice blocks. One of then will contain the Power Star, so Yoshi will need to melt that block.

Star 4: Whirl From the Freezing Pond
This time, Mario should travel to the other side of the level where there is a small pond with really cold water; unlike the cold water below the Chill Bully, Mario can swim in this water, but the water will drain his health, regardless of if his head is above water. The player should walk the small path and then see a large wall across the water. Using a Spindrift to spin jump, Mario can fly over the wall and find himself in an area with two boxes. One of them contains the elusive power star. The player can also use Hoot to get there.

Star 5: Shell Shredding For Red Coins
Following the same path as in the previous mission, Mario should find himself near the two yellow blocks. The box that doesn't contain a powerstar will hold a Koopa Shell. While riding this shell, Mario is able to travel over the water making him immune to the water's effect. Two Red Coins are located on the snow wall to the right of the shell's location. To find the other coins, the player should travel around the rest of the course collecting the rest of the coins. Once all eight have been found, the Power Star will appear above the Star Marker near the entrance of the level.

In Super Mario 64 DS, the title of this fifth Star is changed to Snowman's Silver Stars, and some of the level's elements are also different: now there are five Silver Stars, and three locations from Super Mario 64 have been eliminated.

Star 6: Into The Igloo
In this mission, Mario must get the star from the igloo. To find the igloo, Mario needs to go behind the freezing pond where the shell was found in the previous mission. One again, he needs to hit the yellow block on the right side and get on the shell that comes out of it. Then he needs to go back to the pond where he will see a steep slope with coins on it. He couldn't normally reach there, but because the shell can go up steep surfaces, the plumber can go up. Afterwords, Mario will have to jump over the fence and crawl into the small tunnel leading to the igloo.

But the mission still isn't done after that. Mario will see a star on a wooden platform, but it is encased in ice, so he can't get it yet. To go through ice, Mario will need to get a Vanish Cap and go through it. He will have to maneuver through the igloo until he reaches the top right corner were a blue block is found with the cap inside it. Mario needs to simply jump over the ice wall and get the cap. Since Mario can go through ice when invisible, he will need to go over to the star and grab it in the ice.

In Super Mario 64 DS the interior is completely different, therefore, the star is reached differently. The player will need Luigi and enter the igloo. Then the star can be found under a caged floor. Luigi will need to go to the top left corner to get a Power Flower and turn invisible. Then he must simply go through the floor and grab the star.

Star 7 (DS): Red Coins in the House
Here, the player will need to enter the igloo. Above some Icy water in the igloo, the player must grab all eight red coins in this Super Mario 64 DS-exclusive level. Many enemies are scattered inside the igloo, so the player should avoid them and the icy water below.

Trivia

 * The beta name for this world in Super Mario 64 DS (as seen in debug mode) was "Snow Land".
