This snow-covered level marks the first appearance of Bullet Bills and Bill Blasters in the game and introduces a new variant of Hammer Bro, the Ice Bro. Its completion unlocks World 3-3, World 3-, World 3-, and an Enemy Course.
The stage starts with snow-covered hills patrolled by Goombas and three Bill Blasters, along with the first Star Coin. The next area has an Ice Bro, more Bill Blasters and a Block containing a Starman. Located nearby are platforms with coins and a Yoshi Egg. The players then pass through an area infested with Bill Blasters and moving platforms, after some Brick Blocks, followed by the flagpole.

- Star Coin 1: The first Star Coin is floating high above a platform with a red Koopa Troopa. Mario and co. must bound off the Koopa Troopa to reach the Star Coin.
- Star Coin 2: Not far after the midway point, there are four Bill Blasters surrounding a green Warp Pipe. This pipe leads to an area with three more Bill Blasters and the second Star Coin which is floating high-up in the air. Mario and co. can reach it by bounding off the Bullet Bills that are launched from the Bill Blasters.
- Star Coin 3: After exiting the area with the second Star Coin, Mario and co. should jump up to the nearby midair platform with the red Koopa Troopa, then to the moving platform with the Ice Bro near another midair platform, and finally to the midair platform above which the third Star Coin rests.
