'''Shifting-Floor Cave''', or '''Rock-Candy Mines-7''', is the seventh course of [[Rock-Candy Mines]] in ''[[New Super Mario Bros. U]]''. 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 Top]]s are found with a [[Warp Pipe]] that leads to an underground area. Another Spike Top and some [[Swoop]]s are found, followed by the first group of [[Cross Lift]]s. [[Piranha Plant]]s 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 Troopa]]s 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 Block]]s. Big Piranha Plants are found near the end of the area, where a Warp Pipe leads above ground. The [[Goal Pole]] is then found.

|The third Star Coin is underneath the [[Warp Pipe]] that leads to the [[Goal Pole|flagpole]]. It can be reached by throwing a [[Koopa Shell]] once the adjacent Cross Lift begins receding.
