Morton's Compactor Castle

Morton's Compactor Castle, or , is the Castle course of Layer-Cake Desert in New Super Mario Bros. U. It is unlocked via completion of Blooming Lakitus, and its own completion opens a fork to both Sparkling Waters and Frosted Glacier.

Layout
The level begins with stone blocks that constantly move back and forth, which can crush the player. Two ? Blocks are found in between the platforms, one of which contains a power-up. Using a Mini Mushroom, the player can climb up a wall that leads to a hidden area with coins. Lava Bubbles are found jumping out of pits of lava, and are followed by platforms with Dry Bones on them and moving blocks in the lava below. A Big Dry Bones is found, prior to a section in which the player passes through multiple moving blocks in order to continue. A hole in the ceiling can be once again accessed by using Mini Mario, and leads to an area with multiple coins and a ? Block containing a 1-Up Mushroom. The Checkpoint Flag is found, with a Dry Bones and a ? Block containing a power-up nearby. A section of moving blocks above the lava must then be crossed. A Green Ring and a Dry Bones are on a platform above a moving block. A passage containing a large amount of Lava Bubbles follows. The player must then cross the lava with moving blocks, with coins indicating sections in which there are openings. The boss door is then found at the end of the area.

During the boss battle with Morton Koopa Jr., he ground pounds the ground, causing a shockwave that can stun the player and causes a Big Pokey to appear. Morton uses his magic hammer to then knock Big Pokey segments at the player. After he is jump on three times, he is defeated.
