Big Kahuna Island

Big Kahuna Island was an island on Mobius located near the Devil's Gulag and was home to West Robotropolis. It was used as a secret base by Snively and a group of other convicts after their escape from the Devil's Gulag. Sonic the Hedgehog and members of the Royal Secret Service travelled to Big Kahuna Island via a submarine to retrieve Nate Morgan, who had been captured by Snively and his goons. (StH: #68, #70)
