Add deeper oceans!

Make the oceans deeper, like maybe 3 biomes, Really deep ocean, really deep cold ocean, and really deep frozen ocean. Also add a neutral mob thats like a long serpent and if you look at its glowing orange eyes it attacks you. Also add like anglerfish, maybe make the oceans go as deep as maybe y-50. Also, if you go deep enough into these oceans, like around y-0, the light wouldn't reach the water so it would be darker. and maybe in these oceans, some better ocean ruins with better loot would generate.
