From the Super Mario Wiki
Fireballs are fire-cloaked enemies encountered in Super Mario RPG: Legend of the Seven Stars. Fireballs resemble floating blue spheres on fire with eyes. Mario and his partners found these pyrotechnic enemies in Booster Tower. Due to their low HP and defense, they wouldn't last long in battle. However, because of their high attack and magic attack, Mario and allies must take them out before they get to attack, or else be dealt by a harsh blow. They can deal damage and recover HP with moves like Drain and Mega Drain. Fireballs have other two relatives, Podoboos and Pyrospheres.
