Spike's Spouting Sands, or Layer-Cake Desert-4, is the fourth course of Layer-Cake Desert in New Super Mario Bros. U. It is unlocked by completing Stoneslide Tower, and completing this level unlocks Blooming Lakitus, while completing it via the secret exit unlocks Piranha Plants on Ice.


The level begins next to a Spike on a Flying ? Block. A Sand Geyser is found next to another Spike on a Flying ? Block, and multiple other Fling ? Blocks can be found. Some stationary Stone-Eye platforms and some semi-solid platforms are found throughout the area, above a pit. More Spikes and Flying ? Blocks are found, as well as another Sand Geyser. A group of four Flying ? Blocks is found, with the one at the top containing a power-up. A Spike is on a Sand Geyser, as well as Flying ? Blocks with Koopa Troopas on them. More Sand Geysers are found, along with the Checkpoint Flag. Three Sand Geysers and a Spike are found, with Flying ? Blocks above them. More Flying ? Blocks with Koopa Troopas on them are found. After the Sand Geysers, a Warp Pipe that leads to an area with a Mini Mushroom is found in a portion of the wall. A Spike is found on a Flying ? Block, and a section with a Paratroopa and some Sand Geysers follows. A section with more Sand Geysers and Spikes on Flying ? Blocks leads up to the Goal Pole.

Star Coins

  • Star Coin 1: The first Star Coin is found below a structure of semisolid platforms.
  • Star Coin 2: The first Sand Geyser after the first Star Coin has a vine above it that leads to a room with the second Star Coin. Stretch Blocks act as platforms that allow the player to reach the Star Coin.
  • Star Coin 3: After a hidden room with a Mini Mushroom, the player must dash through various Sand Geysers to reach the final Star Coin.

Secret Exit

Using a Mini Mushroom, the player must head to the structure left of the Spike that comes after the third Star Coin to get to a Pipe Cannon that leads to the secret exit. The secret hole is found at the very bottom of the tower. Alternatively, the player can also run and crouch to slide through the small hole, although when the player enters, the coins are out of reach without Mini Mario. The exit unlocks Piranha Plants on Ice.
