IMG_0106.JPG , originally uploaded by dash16 . This is a green Koopa Troopa from Super Mario World. Green shells swallowed by Yoshi when spit back out stay as shells. Red shells turn into fireballs. Yellow shells allow Yoshi to stomp really hard and defeat some enemies without even touching them. Blue shells allow Yoshi to fly.
