Shifting Floor Cave

Shifting Floor Cave is the seventh level of Rock-Candy Mines in New Super Mario Bros. U.
==Overview==
It is unlocked via completion of Screwtop Tower and its own completion unlocks a red Toad House, Roy's Conveyor Castle, and a path to the first point after Grinding-Stone Tower.
==Layout==
The level begins above ground, where two Spike Tops are found with a Warp Pipe that leads to an underground area. Another Spike Top and some Swoopers are found, followed by the first group of Cross Lifts. Piranha Plants are found on the ceiling above the group of Cross Lifts. The section of Cross Lifts continues, where more Piranha Plants and Swoops are encountered. Two Koopa Troopas are found on a stationary section of the ground, with a ? Block containing a power-up that moves along with a Cross Lift in the ceiling. Another Cross Lift is found, along with a Big Piranha Plant. The following section contains Spike Tops found on red platforms that bounce slightly when hit from below. More Cross Lifts are used to cross a pit, where more Swoops and Piranha Plants are encountered. A Koopa Troopa is found below a row of Brick Blocks. Big Piranha Plants are found near the end of the area, where a Warp Pipe leads above ground. The Goal Pole is then found.
