Fire Flower

When you pick up Fire Flower,it allows you to shoot Fireballs.You can combine this with the cheat code:flamethrower,to throw more fireballs and kill all enemies in your way.This powerup has more looks in Super Mario Bros X,because SMBX uses sprites for SMB 1,2,3 and World.Some enemies in the game are imune to fireballs,like the underground koopa's with dark shells
