The ice is slippery with Flurrys and Trouters appearing. The first A Coin is above the end of the first trail. The 2nd A Coin is at the edge of one trail before the next trail above it. Grab a door potion and place it by 5 vegetables to find the first Yoshi Egg in sub-space. The 3rd A Coin is at the edge of another trail. At the landing strip, grab a door potion and place it by the vegetable in the gap to find the 2nd Yoshi Egg in sub-space. Pull a vegetable that reveals a rocket and you’ll be taken to the mountains. Next, you’ll see Shy Guys riding Autobombs. When they’re riding on an Autobomb, the front cannon will shoot fire. Duck and jump for the 4th A Coin above while riding the Autobomb. Continue ahead and you’ll see some more Flurrys and Autobombs. Power jump at another spot for the 5th A Coin. At the end, you’ll see the jewel that opens the Mask Gate.
