Go to Snowman's Land (Course 10) and get to the snowman's head. Instead of crossing the bridge with the penguin's help, let the snowman's breath blow you off the bridge. Your hat will fall off. Don't go pick it up -- leave it there! Lead your hatless Mario past the gray star spot; the small, pop-up snowman; and toward two pine trees. The second tree of the two is in the corner and it's a teleport. Take the teleport. Now step back and teleport yet again -- in fact, do this at least three times. Once you've teleported a few times, go back to your hat and look at it carefully. Examine it from all sides. What you'll see is a bunch of hats stacked up on each other. Slowly approach the hats. Pick up the one hat and Mario will put it on his head, and the other hats will stay there on the ground! Now, pick up the other hat(s), and Mario will put the hat in his hand and carry it around with him! He can whack baddies with it, and he won't put it back on until you either teleport with him, get a star, or leave the level. One warning: When Mario has his hat in hand, he will take double damage.
