Set of 4 cardboard treasure islands that are shuffled and stacked next to the exploration board. If you assign 2 fish to them, you can explore a treasure island instead of a nearby or distant island.

Was part of the pre-order bonus for those whom pre-ordered the game at the Portal Games webshop and will be for sale later on the webshop of Portal Games. It was packaged by itself and separate from the base game.
