The sea floor in Minecraft is notoriously boring. There’s dirt, sand, a bit of slow sand here and there, maybe some clay if you’re really lucky, but all those things are flat brownish blocks that really don’t excite the player very much. If only there was more color down there. If only there were plants and living things. After all, in the real world living things tend to quite like the sea. Life evolved from the sea. By jove, the lack of sea life really undermines the believability of the entire Minecraft experience.
