Super Mario All-Stars - Super Mario Bros. 3 - World 5-Airship

Enter the castle and Toad will explain that the king has transformed. The next airship has cannons all over. The ones attached to the walls shoot cannonballs and the side cannons shoot Bullet Bills. Once you go far, go down the pipe to take on Roy Koopa. Since Roy is heavy, when he hits the turf, you’ll be stunned for a bit if you’re on the ground. Stomp Roy 3 times to take back the stolen wand and the king will return to normal. You’ll receive a letter from the princess that explains that enemies trapped in ice will come to life when thawed out. You’ll also receive a Bypass Cloud item.
