Air Cannons are enemies that can only be found inside the Airway in Mario & Luigi: Bowser's Inside Story when pursuing the Dark Star. They are a teal-colored egg creature that have been influenced by the Dark Star and operate a red Bill Blaster-like cannon.

With the defeat of the Dark Star, the creatures were completely eradicated or returned to their natural state.
