New Super Mario Bros. X/World 2-7

2-7, is a seventh course hidden in World 2 of New Super Mario Bros. X. Although this is a World 2 level, the course is actually situated on a block of ice in World 3 to the right of the cake structure. To reveal this level, the player must locate the normal exit in World 2-6. Finishing this level will unlock World 2-Castle.
==Layout==
All of the foreground is slippery ice. In some spots, Venus Fire Traps are placed where they are able to melt the bottom part of the ice blocks, so the ice blocks can either fall on the player, or cause them to miss a jump and fall into the pit.
==Star Coins==
*Star Coin 1: Near the beginning of the course is a Warp Pipe. Reach it before the ice block blocks it to get the first Star Coin.
*Star Coin 2: Right before the first slope after the green ring, use fallen ice blocks to reach a Warp Pipe in the sky that leads to the second Star Coin.
*Star Coin 3: After a long series of floating ice blocks.
==Enemies==
*Venus Fire Traps
*Snow Spikes
*Koopa Troopas
