Mossy Underwater Shores

So in the latest snapshots, there's just so much water to the point that we're toast when all we have is an underwater ocean. I love that idea, honestly! However, like before 1.13, these underwater caves are so bland and lame and sad, so it's best to add foliage on the shores of these underwater caves. Best bet; an existing block: Moss!

It's best for the foliage of Lush Caves to actually extend to portions of large cave oceans and have some moss patches here and there to add some life to the shores of these large caves.
