Fire Mini Mario

From the Super Mario Wiki

The Fire Mini Marios are what a Mini Mario becomes when it touches a Fire Flower in Mario vs. Donkey Kong 2: March of the Minis. By transforming into this, the Mini Marios will be able to shoot fire rapidlly for a short time which is usually used to topple a Capture Kong, and it will let Minis escape from it or on certain levels have team work with one standing on a block, and have one below it to hit it, and it shall take down a foe with other Mini Marios beyond it to get past.
