Cocoa Island/Pre-SGW

Cocoa Island is a remote island in the south-western Mobian Ocean on which Tails has a workshop. He found it in 3235 when he was heading home from his adventure in Downunda during the First Robotnik War. When Sonic was thought to have perished during the Xorda Attack on Mobius, Tails used as his home way from home to help him cope through "dark times". While Tails initially record the island as having to smaller sister islands when he first serveyed the aera, third island was found when he brought Bunnie Rabbot-D'Coolette and Antoine D'Coolette there for an overdue honeymoon.

The third island turned out to be a well-disguised Battle Fortress of an organization known as the Battle Bird Armada, who observed the trio secretly for several hours before launching a landing party. In the ensuing confrontation, the island's jungle was set on fire, and the D'Cootlettes were subdued while Tails was forced to hide from Speedy, the sixeenth Battlekuuku. Tails then set about exploring the Arada's operations after rertieving the Sea Fox, only to engage several of their sumbersibles off the coast  (SU: #17, #18)

With a water-based entrance no longer an option, Tails, T-Pup, and the recently rescued Antoine went into the island's robust cave network to locate a tunnel bbelow the seabed that lead to the Armada's base. The cavern tunnels further underground appeared to have been carved out by some ancient civilization that had long since left the island and may been what gained Battle Kukku XV's attention as the Armada was looking for clues to the secret forbears, the ancient Babylonians. The island's ruins were aparently known to the Babylon Rogues as well, who were also looking for relics from Babylon that they believe olny they had the right to take and may have been on Cocoa Island. Regardless, the Armada withdrew after their Fortress took substantial damage thanks to Tails, and the Rogues then went on an intercept course with the Armada, allowing allowing Cocoa Island to return to its peaceful state (StH: #19, #20)
