I would prefer if this was more of a pliosaur; having long back flippers and shorter front flippers, with the head of a mosa, but the whole creature being about the length of a Liopleurodon when it is Adolescent, and being able to torpedo thru the water to catch prey. Also, they should not have made it a miniboss, but more of simply a rare creature, maybe 10-15 per map.
