Ground-Pound Switch

A Ground-Pound Switch is a type of switch first seen in Super Mario Galaxy. To use this item, Mario must ground pound it. Upon pressing this switch, a variety of things can happen, mainly making Star Bits or coins appear.
There are also timed Ground-Pound Switches, tree stumps which have similar effects, and gray Ground-Pound Switches that make walls fall down, making other areas accessible.
They are shown again in Super Mario Galaxy 2, having the same functions as in the first game. There is also a new function for Ground-Pound Switches in this game. If Mario ground pounds one of the switches, the screen turns grayscale, and the environment and enemies on the respective planet slow down greatly. This new function appears in the Space Storm Galaxy, Clockwork Ruins Galaxy, and Stone Cyclone Galaxy, and is useful in avoiding stage hazards that would be impossible to dodge otherwise. 
Ground-Pound Switches reappear in Super Mario Odyssey. One can be found on top of a skyscraper in the Metro Kingdom. Ground-pounding the switch causes a platform to temporarily appear, allowing access to another building. Four Ground-Pound Switches are also found around the Seaside Kingdom, each one guarded by a cage that can only be opened by collecting the Power Moon next to them.
