Mario starts out on the submit of a tall mountain. Going foward will lead to a cabin with a chimney and a fireplace with a Baby Penguin. Going a bit more foward will go to a slope, which leads down the rest of the mountain. Going through the chimney in the cabin leads to a large cavern, with a humongous slope. In Mission 3 and after the player collects all 120 Power Stars, a penguin will challenge Mario to a race. Two ways may be taken. The First way is by going normally down the slope, eventually entering a cavern, then Mario must cross some Web Blocks to reach the cabin floor. The Other way is when there is a wall with coins leading straight into it, if Mario follows the coins, he will go through the wall, leading to a narrow cavern with many 1-Ups. Falling through a hole at the end will reach a ledge on the cabin floor. After going down the slope back on the mountain, The player may jump at a fenced area to reach a ledge with a Red Coin and lots of ice. Continuing down the slope reaches a joint where Mario will start going the opposite direction down another slope. At the end of this slope, there is a wooden platform with a snowman's head. Going forth reaches a bridge with jumping snowmen that will try to hurt Mario by throwing snowballs at him. Going forward will reach the roof of the lower part of the cabin, and after going down a path, Mario will reach a platform with an unenterable door(which is the exit of the cabin) and a Mother Penguin. If the player gets the baby penguin from the top of the mountain, the mother will give Mario a star. Going right will lead to a place with a bridge connecting a platform, and with another broken bridge. If Mario stands on the end of this broken bridge, he will be teleported to a bridge behind where Mario started at the top of the mountain. Going left will go to a place with a cannon and an elevator. Going up the elevator he may jump to a platform with a Bob Omb Buddy and open the earlier mentioned cannon. Continuing up the elevator will lead back to the platform with the snowman's head. Using the cannon on the lower platform Mario will see another platform with a tree. If Mario aims there, he will meet another platform which heading on a path down will introduce Mario to a three leveled platform which Mario must use Wall Jumps on the mountainsides to climb. On the middle platform, the mountainside is especially difficult to climb, however, Mario may use the wall facing the camera for a much easier jump. After climbing the platforms, a Power Star awaits at the top.
