Gray P Switch

Gray P Switches (or Gray P-Switches ) are objects in Super Mario World. They appear identical to normal Switch Blocks except that they are gray with a pink rim as opposed to blue with an orange rim. When pressed, they turn all enemies that are onscreen into Gray Coins.

Trivia

 * In Super Mario Bros. 3 for the NES, Switch Blocks appear in a gray palette in the fortress levels, predating the Gray P Switches.
