Wendy's Shifting Castle

Wendy's Shifting Castle, or , is the Castle of Frosted Glacier in New Super Mario Bros. U. This level contains swinging girders, Dry Bones, and Thwomps. The boss is Wendy O. Koopa.

Level Overview
The player will first jump across some swinging girders while avoiding some Dry Bones. Next, the player will pass by some Thwomps and Big Thwomps and reach the checkpoint. The next part will have more of these swinging girders, Dry Bones, Thwomps, Thwimps and a Big Dry Bones. After the check point, the player can find a hidden area filled with coins on the first platform with two Thwimps. After passing some more Super Thwomps, the player will find and enter a blue door which leads to a red cannon. After being launched out of the red cannon into Wendy's airship, the player will proceed to fight Wendy O. Koopa. She uses her candy rings to knock icicles from the ceiling onto the player and, at the same time, skates across the area to avoid the player. After three hits, she is defeated and the path to The Mighty Cannonship is unlocked.
