Giant Skewer Tower (Giant Spike Pillar Tower in the British English version) or Sparkling Waters-Fort Icon.pngTower, is the Tower course of Sparkling Waters in New Super Mario Bros. U. It is unlocked via Tropical Refresher, and completing the Tower unlocks Haunted Shipwreck, and a cutscene of Peach's Castle being completely shrouded in Kamek's tornado. However, the cutscene does not play if Freezing Rain Tower is completed beforehand.


Similarly to World 4-Castle of New Super Mario Bros. Wii, this is a water course filled with Spike Pillars.

The level begins in a area with Jump Blocks leading to a Warp Pipe. The next section is filled with water, and there are current-pumping Warp Pipes at the beginning of the area. The area contains multiple Spike Pillars that come out of the walls, and the player must go through sections in the wall to continue. A Red Ring is found to the left of the area. The player then exits the water, with a lift at the surface, as well as Jump Blocks. A section with more Jump Blocks and lifts follows, with Spike Pillars acting as obstacles. Another Spike Pillar, as well as a Dry Bones and a Super Dry Bones, are found before the Warp Pipe leading to the next section. A red Warp Pipe is hidden in the wall to the right, allowing the player to access a P Switch in the area with the Checkpoint Flag. More Jump Blocks, Dry Bones, Spike Pillars, and a Big Dry Bones are found as the player climbs the section. After a section in which Jump Blocks are used to reach semi-solid platforms, along with two Spike Pillar, the boss door is found.

Boom Boom is the boss of the tower. Kamek flies in and give him the ability to jump. Unlike in Stoneslide Tower, however, Boom Boom keeps his spin attack, even after getting stomped on.

Star Coins

  • Star Coin 1: Where the first Spike Pillar is, the player must go to the wall on the left for the first Star Coin.
  • Star Coin 2: The player must use the Jump Block to reach the second Star Coin in the air.
  • Star Coin 3: The third Star Coin is similar to the second Star Coin, only this one is above a Spike Pillar. The Star Coin can also be obtained via POW Block.
