Piranha Plants on Ice

Piranha Plants on Ice, or Layer-Cake Desert-Ice, is a secret course hidden in Layer-Cake Desert of New Super Mario Bros. U. Presumably, this course is situated in, or on, the large cake-like structure between Layer-Cake Desert and Frosted Glacier. Unusually, despite being an ice course with Frosted Glacier backdrops, this course is considered a Layer-Cake Desert course.

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.

Enemies

 * Venus Fire Traps
