Raging Sea Biome

The Raging Sea Biome has large waves, whirl pools, and Serphants. The whirl pools will be able to pull mobs and players in and drowns them. The Waves will crash boats and entities will drown. As for the Serphants, they will deal 12 health points of damage unless wearing armor. I would like this because it will make water travel more interesting, and Ive been wanting serphants to be added.
