The Star Fox 64 Official Player's Guide gives Aquas' boss Bacoon a very different backstory from the official Japanese guidebook. The latter says that Bacoon is simply just a bioweapon made by Andross, but the former gives it a more elaborate background, claiming that it was an ancient monster that was jealous of the ancient civilization and their temples/islands above the ocean's surface, and overtime it learned how to control the other aquatic lifeforms within Aquas' oceans, such as the explosive Starfish, which were then commanded by Bacoon to migrate to the ice cap and detonate, resulting in the polar cap being melted and all of the islands submerged into the sea forever, essentially explaining the ancient undersea ruins throughout the Aquas stage.
