New Super Mario Bros.: 5-3

It's time for another ice slide! Stay sliding until you stall to take out enemies for a 1-up. Jump to the right from where the ice plateaus to get the first Star Coin. When you land, you'll find some blocks. The highest item block contains a vine so you can reach the next ice slide. Underneath the area with the vine, break the blocks for the second Star Coin. The low road is more difficult with Snailicorns. The high road has lots of sliding. You can wall jump up the ice or drop down the gap to reach the third Star Coin. Slide down the ice and jump before you reach the end to reach the flagpole.

New Super Mario Bros.: 5-B

This is an ice level. We'll find a new enemy, the Snailicorn, which looks like a snail shell with a pointy nose. We can't defeat them, but can stomp on them and they will slide to the left or the right. Push them off ledges to get rid of them. We're going to slide down the ice a couple of times, then get the first Star Coin under a ledge using a Paratroopa shell or just jumping for it. The item block to the left contains a brick block. The P-Switch will convert brick blocks to coins so we can jump and slide over the ice to get the second Star Coin, which is protected by brick blocks. The third Star Coin can be reached by taking the lower path and getting past the Snailicorn. Keep going to reach the flagpole.
