Turning Floor

Turning Floors are continually moving objects that appear in Mario platformers. They are large, circular or semicircular platforms that turn clockwise or counterclockwise, moving anything on them as they do so.

Mario Kart DS
In Mario Kart DS, Bowser Castle has a Turning Floor that periodically changes direction.

Mario Kart 7
Hollow Turning Floors appear in Mario Kart 7. There is one before the underwater area in Bowser's Castle; racers can pass through it, or use an alternate path to drive on top. After the start of the third section of Rainbow Road, there is a Turning Floor with Dash Panels and Glide Ramps inside.

Mario Kart Tour
In Mario Kart Tour, 3DS Bowser's Castle and 3DS Rainbow Road retain their respective Turning Floors. In the T variant of 3DS Bowser's Castle, an additional Turning Floor is present after the finish line that players can drive through by using the Glide Ramp before the finish line.

New Super Mario Bros. Wii
New Super Mario Bros. Wii features Turning Floors of various sizes in World 1-1, World 1-6, World 6-2,, and World 8-2. They are partly embedded in the ground or overlapped with other Turning Floors. Often, there are rows of coins or Dash Coins that move along with them, and in common instances they also carry enemies such as Goombas, Paragoombas, Hefty Goombas, and Spike Balls.

New Super Mario Bros. U / New Super Luigi U / New Super Mario Bros. U Deluxe
Turning Floors reappear in New Super Mario Bros. U, New Super Luigi U, and New Super Mario Bros. U Deluxe, acting in much the same way as previously. They are encountered in the levels Yoshi Hill and Blooming Lakitus in the former, and in Rolling Yoshi Hills and Spinning Sandstones in the latter.

Icy Turning Floors also appear in the New Super Mario Bros. U level Prickly Goombas! and its New Super Luigi U counterpart, Fire and Ice.

Super Mario 3D World / Super Mario 3D World + Bowser's Fury
In Super Mario 3D World, Turning Floors are most notably seen in Really Rolling Hills and its World Mushroom counterpart, where Skipsqueaks and Spiny Skipsqueaks will run opposite to the direction the Turning Floor is moving, keeping themselves centered on the platform. Other entities, such as Galoombas and items summoned from the Item Storage, will also move in the direction of the Turning Floor if they remain stationary.

Mario and other characters can progress by walking or running in the opposite direction, jumping forwards, or many times simply avoiding the platform altogether. However, fully circular, mandatory Turning Floors appear in Rainbow Run, along with Skipsqueaks. The direction and speed of Turning Floors varies greatly. Skipsqueaks do not appear to change their running speed to account for this, yet still appear on the center of the platform.

A very large, circular Turning Floor appears in the twenty-sixth room of Mystery House Marathon, where the character must stay on top of it as it moves to reach the Green Star at the end. Its design appears to be styled after Cookie Cogworks.

In the Bowser's Fury campaign of Super Mario 3D World + Bowser's Fury, hollow Turning Floors appear in Slipskate Slope, in segmented sections that move left and right. While Skipsqueaks are found on top of these platforms, inside are spikes that Mario must carefully avoid being pushed into while in an Ice Skate.

Captain Toad: Treasure Tracker
Turning Floors appear in all versions of Captain Toad: Treasure Tracker, appearing only in the level Rolling Inferno. They may be colored blue or green, but this is merely an aesthetic change, as their direction of rotation is indicated by chevron arrows imprinted on them. In part due to Captain Toad's inability to jump, once the player crosses a Turning Floor, they cannot move against it.
