Go to either 1-4, 2-4,3-4, etc. and get to Bowser. Make sure you are Big Mario and try to jump over Bowser or run under him. Stand near the Axe and Bowser will start to walk towards you. As he gets near you, jump high, and touch Bowser and the Axe at the same time. If you do it correctly, you will hear the sound as if you were to shrink, but you will just flash and stay as Big Mario. Go to the next stage, and get a Mushroom. (Yes, there will be a Mushroom instead of a Fire Flower.) When you touch the Mushroom, you will shrink. Then get a Fire Flower, and you'll have Fire Power as Small Mario. (Note: after you do the Bowser/Axe trick, enemies that touch you will be able to kill you when you are Big Mario. When they touch you while you are Small Mario after getting the Mushroom or Fire Flower, you will turn back into Big Mario.)

In order to get fireworks to go off after you beat a level, simply finish the level when the last number in the Time is either a 1, 3, or 6. The number of fireworks you get depends on that number. So finish a level with 106 remaining, and you'll get 6 fireworks to explode. Plus, you get bonus points for each firework that goes off.

Hit the flagpole at the end of a level when the last digit of the timer is 1, 3, or 6.
