I made a variation from my deep sea code, used to set "goody Islands" on randomly every 20th Coast-Square. These Islands (the graphic is GarretSidzaka's Volkano) are used like goody huts. It would be possible to change the code, so that these Islands are placed on ocean, to, but I think it would be bad - the AI would perhabs not be able to carry away the units they find in these islands.
