Air Cannon

An 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. It is a teal-colored egg creature that has been influenced by the Dark Star and operates a red cannon. From the cannon, the egg creature will shoot 3 white Bullet Bills in two different ways. In 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 involves shooting 3 Bullet Bills into the air. The Bullet Bills perform a loop-de-loop and head towards the bros. However, as the Bullet Bills come down, they will turn invisible. The brothers 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, but it will come back in 2 or 3 turns if the battle hasn't ended.
