In any of the castles except the last one, as Fiery Mario jump on the axe and Bowser at the same time. This may take a few attempts but if done succsessfully, Mario will turn back into Super Mario (powered up, with a mushroom). In the next level if you get a mushroom, you will shrink and if you get a Fire flower, you'll turn into a Mini Fiery Mario. If you get hurt while you are small, you'll become big. If you get hurt while you are big, you will die. This effect will last until you die.
