Ok, so playing through super mario 3D world, I managed to find a new move. It lets you do a jumping roll. It's not an exploit, as it is basically a glorified version of the long jump, but it still looks cool. To preform it, run until you get terminal velocity. Then, press the ZR button, then X and B, all while holding down Y. Its pretty tricky, but you'll get the hang of it. Any problems, comment.
