Fire Flower

About
The Fire Flower is one of the many power-ups in the Mario franchise, it can give Mario the ability to shoot fire balls at enemies. Mario is able to throw fire balls underwater as well, even though that would be impossible in the read world. Other characters like Toad, Luigi, Peach, and Rosalina could use the Fire Flower as well.

The Fire Flower had it's first appearance in SuperMarioPower in Mario loves Shrimp Soup, even though it was not seen on screen, the sound effect played and Mario turned into Fire Mario. Mario could use it again in Metal Mario, but we do not know yet.
