Touchstone

Touchstones (also referred to as Touch Screen Platforms and rainbow-colored blocks ) are a type of moveable platform that appear in Super Mario 3D World and Super Mario 3D World + Bowser's Fury, as well as Captain Toad: Treasure Tracker and its Nintendo Switch and Nintendo 3DS ports. They can be activated by using the Wii U GamePad, the touch screen of a Nintendo Switch in handheld mode, or the button while using dual Joy-Cons or a Pro Controller, as all of these methods summon the touch cursor. Tapping a Touchstone with the touch cursor causes it to move to a set position until it is touched a second time, which makes it return back to their original state.

In Super Mario 3D World and Super Mario 3D World + Bowser's Fury, Touchstones also revert after a short time has passed. They are mainly purple and appear rarely, found only in Puffprod Peaks and Captain Toad Plays Peek-a-Boo. In Captain Toad: Treasure Tracker, Touchstones can be found in various colors and shapes and are more common, making their debut in the third level, Touchstone Trouble.
