Touchstone

Touchstones (also referred to as Touch Screen Platforms and rainbow-colored blocks ) are a type of movable platform that appears in Super Mario 3D World and its campaign in Super Mario 3D World + Bowser's Fury, as well as Captain Toad: Treasure Tracker and its 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-Con 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 to its 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.

Touchstones also make an appearance in WarioWare: Get It Together!, where they appear in the Captain Toad: Treasure Tracker microgame. In the microgame, the player must push one of the Touchstones to create a slope for Captain Toad to walk on, which leads to a Power Star. If the player pushes the wrong Touchstone, Captain Toad will be blocked, preventing him from obtaining the Power Star.
