Cocoa Island[2] (ココアアイランド[1] Kokoa Airando?), also called Tails Island[3] or Kokko Island,[4] is a location that appears in the Sonic the Hedgehog series. It is a tiny island in the spring-like South Pacific which is not found on any map. Cocoa Island was also where Miles "Tails" Prower lived for an unknown period of time.[1]


Cocoa Island is a floating[1] island located slightly above the ocean. The island is inhabited by many Flickies, and Miles "Tails" Prower as well for some time.[1]

A natural, peaceful island, Cocoa Island has many natural environments, such as forests and mountains. Beneath it, there are many coral reefs. Cocoa Island is also surrounded by smaller islands.


Tails Adventure

Before his first meeting with Sonic the Hedgehog, Tails lived on Cocoa Island. One day though, the island was invaded by the Battle Kukku Empire, whose battleship and battalions of soldiers set Poloy Forest on fire. Waking up from the chaos, Tails met a Flicky who informed him about the empire's attack. Tails then noticed a large mecha in the flames, as the empire's leader, Great Battle Kukku, hunted for the Chaos Emeralds that were hidden around Cocoa Island.[1]

Commencing his first adventure, Tails traveled around the island to gather the Chaos Emeralds. Along the way, he met the Great Battle Kukku's son Battle Kukku XVI in Polly Mountain, took down empire's battle cruiser on the open sea, and destroyed both Mecha Golems in Cavern Island and Volcanic Tunnel. Eventually, Tails discovered a lonely island in the southeast that turned out to be the Battle Kukku Empire's flying Battle Fortress. After Tails took down both Battle Kukku XVI and the Great Battle Kukku himself for good, the Battle Fortress sank into the ocean and peace reigned over Cocoa Island again.

Cocoa Island in the Archie Comics.

In the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics, Cocoa Island was an island on Mobius that was discovered by Tails during the First Robotnik War. It was as well there T-Pup was created. As Tails later brought Antoine D'Coolette and Bunnie D'Coolette to Cocoa Island for the pair's honeymoon, the heroes were attacked by the Battle Bird Armada who had occupied the island. In the end, the heroes drove the armada off the island.


  • As the western instruction manuals of Tails Adventure include altered storylines for the game, Tails Island is specified as Tails' favorite holiday spot and that he had taken a little vacation to the island after his and Sonic's previous adventure before the events of the game.[3]
