Piranha Plants on Ice, or Layer-Cake Desert-, is a secret course hidden in Layer-Cake Desert of New Super Mario Bros. U. Although this is a level in Layer-Cake Desert, the course is actually situated on a block of ice in Frosted Glacier to the right of the cake structure. To reveal this level, the player must locate the secret exit in Spike's Spouting Sands. Finishing this level unlocks a shortcut to Soda Jungle, skipping Frosted Glacier and Sparkling Waters.
All of the foreground is slippery ice. In some spots, Fire Piranha Plants 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.
