MOS Moog’s Ocean Structures Mod populates the sea floor and water surface with over one hundred vanilla-style builds.

Every build uses vanilla blocks and mobs, keeping the original look of Minecraft intact. Players can search through hidden chests, explore dark underwater corridors, and collect valuable loot during seafaring journeys.
