Spike's Spouting Sands

Spike's Spouting Sands, or Layer-Cake Desert-4, is the fourth course of Layer-Cake Desert in New Super Mario Bros. U. It contains Sand Spouts and Spikes.

Layout
The course takes place in the part of the desert with Moai Heads and slanted structures. The main platforms are Moai Heads, but unlike the others introduced, they are completely immobile. Spikes appear in this course and throw Spiked Balls, usually on rising Sand Spouts.

 * Star Coin 3: After a hidden room with a Mini Mushroom, the player must dash through various Sand Spouts to reach the final Star Coin.
