Giant Skewer Tower

Giant Skewer Tower (Giant Spike Pillar Tower in the PAL version) or , 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 play if Freezing-Rain Tower is completed beforehand.

Layout
Similarly to World 4-Castle of New Super Mario Bros. Wii, this is a water course filled with Skewers. The first part of the Tower is underwater, and the most prominent obstacle are Skewers which thrust forward periodically. Dry Bones are the only enemies in the Tower.

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