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, the button while using dual Joy-Con or a Pro Controller, or the  button while using single Joy-Cons, 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 or the timer expires, 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, Captain Toad Plays Peek-a-Boo and Captain Toad's Fiery Finale. 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, 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.
