Large-scale Minecraft mermaid lake ...

Large-scale Minecraft mermaid lake biome, not a small diorama. Actual water blocks covering a large area, with a natural shoreline and deep underwater terrain. A 25×25×15 block mermaid house should be only one part of the environment, not the entire scene. Include a sandy beach, several small islands, wooden docks, and a coastline connecting to a large ocean. Underwater areas should contain kelp forests, coral reefs, fish, a large shipwreck, ancient ruins, caves, tunnels and hidden structures. Show a wide environmental view with lots of open water and exploration space. Magical colorful mermaid theme, detailed Minecraft blocks.
