'''Stoneslide Tower''', or '''{{world|Cake|tower}}''', is the second tower in ''[[New Super Mario Bros. U]]''. It features [[Screwtop Platform|stone platforms that are movable by spinning on wooden screws]].  This level is unlocked by completing either [[Perilous Pokey Cave]] or [[Fire Snake Cavern]], and completing this level unlocks a labyrinth of connected [[Stone-Eye]]s on the overworld map that serve as the location for both [[Goomba]] and [[Fire Bro]] enemy courses. Navigating the enemy courses unlocks [[Spike's Spouting Sands]], [[Dry Desert Mushrooms]], a Green [[Toad House]], and a Red [[Toad House]]. After completing this level for the first time, [[Kamek|Magikoopa]] flies around [[Peach's Castle (world)|Peach's Castle]] and a purple tornado starts to form around it.
==Layout==
The level begins with large [[Screwtop Platform]]s that can be moved by spinning on a wooden screw, allowing the player to reach a [[Warp Pipe]] that leads to the next section. Another screw controls a platform, allowing a [[? Block]] containing a power-up and the platform above to be reached. Two [[Spike Top]]s are found on a portion of the ground. A screw controls a pair of smaller Screwtop Platforms, along with another platform that crushes a group of [[Dry Bones]] blocking the path. More Dry Bones are found, along with a screw that controls two Screwtop Platforms. Three more Spike Tops are found. Another screw is used to control three Screwtop Platforms. On the left wall, there is a [[Hidden Block]] that contains a [[1-Up Mushroom]]. The other one on the right contains a coin. These Screwtop Platforms allow access to a Warp Pipe that leads to the [[Checkpoint Flag]]. Another screw controls a group of Screwtop Platforms, one of which having a [[Mega Dry Bones|Big Dry Bones]] on it. A yellow Warp Pipe on the right takes the player to a room with a [[Roulette Block]]. A Dry Bones is found, along with Spike Tops on Screwtop Platforms. Following more Screwtop Platforms and Dry Bones, a group of [[Pipe Cannon]]s is found. The player must use a screw to move Screwtop Platforms out of the way, allowing the Pipe Cannons to be used to reach the boss door. Two Big Dry Bones are found, as well as a Hidden Block containing a [[Fire Flower]] on the left.

Through the boss door, there is a boss battle with [[Boom Boom]]. [[Kamek|Magikoopa]] appears before the battle, giving Boom Boom the ability to attack using spin jumps. He is defeated after being jumped on three times.

|Above the [[Checkpoint Flag]], the player must rotate the screw next to some quicksand. It causes the Screwtop Platform next to it to rise. The player must run under it and jump along the left wall to discover a hidden warp pipe. Inside, the player must use the screw to move the Screwtop Platform and guide the Grrrols so that they break the [[Hard Block]]s. Then, by carefully avoiding them, the player must go left and grab the third Star Coin.
