World 4-1 (New Super Mario Bros. 2)

Mario begins in front of a slope where several Micro Goombas roam about. They can attach to Mario but can be shaken off by crouching. Following that, there is an ice boulder that works similarly to a Spiked Ball. They deflect upon hitting a wall or gravity pulls them down on a slope. Above that is a ? Block containing a Super Leaf. More Micro Goombas and a larger version of the ice boulder appear, followed by a rope on the ceiling to help Mario cross the area with ice boulders below. Following that is a red Koopa Troopa, followed by another ice boulder rolling up and down slopes on the ground. This is followed by the checkpoint. A ? Block containing a Super Leaf can then be found, followed by some Micro Goombas and ice boulders. Going up the structure, the player will notice to ground switching to ice and thus is slippery. Reaching the top, the player can find a Gold Ring and some Koopa Troopas where he could earn coins by sliding down the slope. At the end of the slope, an ice boulder will roll opposite, so Mario has to duck. Immediately after that is the flagpole.

Star Coins

• Star Coin 1: The Star Coin is located in the area where Mario climbs the rope on a ceiling. There are ice boulders that continuously move about, thus obstructing the path to the Star Coin. Mario needs to get of the rope when he is above a Donut Lift at the right time, preferably on the left or right side instead of the one in the middle. Then the Star Coin is within reach.
• Star Coin 2: Located above the checkpoint. When Mario reaches the slopy part of the level before the checkpoint, where the ground is hilly, Mario will need to jump to the second orange platform with a Koopa. He will need to bounce off the Koopa to find a higher orange platform above. Continuing towards the right will lead Mario to the Star Coin.
• Star Coin 3: When Mario reaches the top of the structure after the checkpoint, the player can notice a ledge furthur up. Jump to that area from the incline in the ground to reach the ledge and find the Star Coin.
