Small Fire Mario is a glitch in Super Mario Brothers that turns Mario or Luigi, into a Small Fire Mario/Luigi.
How to do it
- Be Big Mario or Fire Mario and go to a Castle level (World 3 Castle recommended).
- Try to touch the Axe and get hit by Bowser at the same time.
- When you are in the next level you will be big. Collect a Mushroom and you will turn small.
- Now collect a Fire Flower and you will be transformed into Small Fire Mario/Luigi.
This Glitch will wear off if you get hit by an enemy, therefore turning Small Fire Mario into Big Mario. This is very hard in the fourth world because of the Lakitus.
