This add-on adds no new content to the pack. Its express purpose is to remove the rocky islands and sea stacks from the Ocean, Deep Ocean, Cold Ocean and Deep Cold Ocean biomes. Since the addition of the tropical and Mediterranean islands in the Warm Ocean and Deep Lukewarm Ocean, the rocky islands in other biomes have begun to make the oceans feel a bit crowded. If you would like more open ocean, use this add on above Overhauled Overworld 1.17.
