The 3-Up Moon is an item that first appeared in Super Mario World. It is a yellow, waxing crescent moon that sports eyes and a smile. An extremely rare item, the 3-Up Moon functions very similarly to the 1-Up Mushroom, but true to its name, it instead rewards Mario or Luigi three extra lives instead of one.
