Slap the butterflies in course 2, 12 or 13. You will get a 1UP, but beware, it can also be a boobytrap. In course 10, to get past the snowman, step next to the penguin or jump onto the head of the penguin. In course 23, when the Gomba's are big, you can make them dead by jumping on them. You will get a yellow coin. To get a blue coin ( = 5 yellow coins ), you have to stamp attack them, by pressing Z in the air. In course 1 and 13 there are wooden poles. Walk 3 times around the poles to get 5 coins. When you have beaten the last bowser, you can move the camera with the poke of the second controller during the end movie. Jump on Koopa Troopa and then walk against it. You can use his shield as a snowboard. If you slide the Koopa down you will get a blue coin. When you lose your hat in course 7 or 10, don't try to grab it, but just walk to the nearest warpzone and the grab your hat. If you are close to it, walk slowly towards it, and you will notice that Mario takes the hat, and you see another one below it. When you repeat this cheat, you get more hats. In course 10 you can try to grab you hat with the B button. Now, Mario will hold the hat in his hand and can beat enemies with it. He will put his hat back on again when you grab a star, leave the level or warp again.
