Freezing-Rain Tower, or Frosted Glacier-Tower, is the Tower of Frosted Glacier in New Super Mario Bros. U. It is unlocked via completion of Cooligan Fields, and its own completion opens the path to Prickly Goombas! and a cutscene of Peach's Castle being completing shrouded in Kamek's tornado. However, the cutscene does not play if Giant Skewer Tower is completed beforehand.
Similarly to Icicle Caverns and World 3-3, icicles act as the main obstacles. The level begins with a ? Block containing a power-up. The player then climbs up sloped platforms with icicles above them, as well as large icicles that act as platforms. A section with more large icicles follows, and they are used to reach higher platforms with Dry Bones on them. A pair of large icicles allows the player to reach a long, tilting platform with a Dry Bones on it. A Red Ring is found underneath a row of icicles on the ceiling. Another sloped platform follows, along with a large icicles, a tilting platform, and a long row of icicles on the ceiling. The Checkpoint Flag is found, along with platforms leading to a lift. The lift begins to rise, passing platforms with Dry Bones on them, as well as icicles. Prior to the boss door, multiple rows of icicles, a group of Dry Bones, and a POW Block are found. The boss door is found at the top of the area, with two large icicles on either side.
A fourth Boom Boom is the boss of the tower. Kamek flies in and gives the Boom Boom the ability to jump. Unlike in the second round, however, this Boom Boom keeps his spin attack, even after getting stomped on.
