Layout
The level is an ice-themed level, which primarily features Bumpties and short jumps, as well as Donut Lifts and Stretch Blocks in some areas. One point in the level is an auto-scrolling area in which the screen begins to move back and forth, moving faster each time and revealing more of the area until a Warp Pipe becomes visible, at which point the screen stops scrolling.

Advance Coins

 * 1) On the platform of ice to the left of the Amazing Flyin' Hammer Brother is a red Koopa Troopa, and later is a Warp Pipe. The Ace Coin is in the pipe, underneath two frozen Coins. The player must use Fire Mario's fireballs and the Koopa Troopa to get it.
 * 2) The Ace Coin is on a set of Donut Lifts only accessible by using a flight power-up.
 * 3) In the second area of the level, the third Ace Coin is located on the second set of Stretch Blocks in the area with the Donut Lifts between them.
 * 4) If the player stands on the center of a set of three Donut Lifts, he or she drops down to an ice block below; continuing down, the Ace Coin is hovering over the pit at the very bottom.
 * 5) In the third area of the level, the Ace Coin is on the very left side of the room.
