Air Cannon

Air Cannon is a blaster manned by an egg-shaped creature. It can only be found inside the Airway in Mario & Luigi: Bowser's Inside Story. They are teal colored egg creatures that have been influenced by the Dark Star and operate a red cannon. From the cannon, the egg creature will shoot 3 white Bullet Bills in two different ways. The first and easiest to avoid, the Air Cannon will shoot 3 Bullet Bills randomly straight at Mario or Luigi. Occasionally, they may "disappear", but they actually turn invisible. With key timing, the plumbers will need to jump over the Bullet Bills to avoid taking damage. Their second attack includes them shooting 3 Bullet Bills into the air. The bullets would then proceed to perform a loop-de-loop and head towards the bros. However, as the bullets come down, they will turn invisible. The brothers would need to jump on or over the Bullet Bills with key timing in order to avoid taking damage. Once the cannon is defeated, the creature operating it will flee.
