A mod that diversifies the oceans and adds several marine mammals from the cetacean family. Currently, the largest is the humpback whale. There is also a bowhead whale that you can ride. Smaller ones include the beluga whale, the pilot whale, and the Shepherd's beaked whale. That's all for now. Of course, this mod won't be just about cetaceans.
