Water Plains

This biome would be a new type of water biome. It would be a large expanse of water, either next to the sea, or by itself in other biomes such as forests, or jungles. The water would be one block deep and cover an expansive area. You would commonly be able to find seagrass. This being common in the biome, turtles could be more commonly found and available, allowing breeding to be easily accessed to high-level players you would also rarely coral blocks, and tropical fish swimming around them.

This biome could also be used to find rice plants, that drop rice seeds if it was added to the game (as mentioned in TortugaOnline's post about rice).
