Countdown Platform

Number Platforms, originally named Countdown Platforms, are numbered platforms that first appear in Super Mario World, but have since exclusively appeared in Yoshi's Island games, specifically Super Mario World 2: Yoshi's Island, Yoshi's Island DS, Yoshi's New Island, and Yoshi's Woolly World. Number Platforms appear as a balance with a number labeled on them, with the number shown decreases by one every time something moves on them. When the number decreases to where zero would be, the entire platform instead vanishes in a puff of smoke. They typically range from a highest display of four to a lowest of one, but in Yoshi's Woolly World, some go as high as nine. These platforms don't countdown if the player has Yoshi still on them; they only decrease if Yoshi steps off or jumps off them. In most games, Number Platforms can only be activated by Yoshi; every other object passes through them. However, in Yoshi's Woolly World, Shells can also trigger these platforms.
