Bombshell Bills are gold Bullet Bills that come out of a Bombshell Bill Blaster. Their attack is also the same as a Bullet Bill, they hurl themselves at Mario and self-destruct, instantly killing themselves. An easy way to defeat Bombshell Bills is to use a Fire Flower or other fire related item, such as an Egg Missile. A hammer or jump attack also works, but because of their defense, this method is best for defeating them.
