water crouch tech | Super Mario Bros. Wonder

look how slow it is to fall in a body of water and jump out again. if you hold crouch while you fall in, then press jump the moment you touch the water, you'll skip across quickly and maintain your momentum
only works in Power-Up stage 2 or 3, because it's based on your size. when you suddenly go from one block tall to two or more after hitting the water, it puts you above the surface for a frame or two where you can jump out instantly
it's most lenient with the elephant ability due to it making you three blocks tall
