Bacoon is an undersea bioweapon made by Andross. He is seen in Star Fox 64 on the water planet Aquas. Shaped like a clam, Bacoon is mounted with cannons on his head. They can easily be shot down, but come back up after shooting the tendons. The tendons must be shot down to get to the power source: the eye in the center. Once the eye is destroyed, he's finished. The catch is, you're not using an Arwing; you're using the Blue Marine. It has been said that Bacoon was responsible for polluting Aquas and sinking the ancient city. Since the city sunk, Aquas was from there on 100% water.
