Well, this creature Just have ONE limited use, but it surely makes the difference. Not as powerful than a Megalodon, and not as fast than a Ichtyosaurus, this is One of the almost useless tames(ALMOST). It’s unique use is to farming oil, due to it’s capacity to farm rocks in ocean. Also, if is a high level tame, you can protect yourself during farming oil, which is easier than Going to the deep with an Ichty and dismounting to farm oil with the pickaxe. 100% hype, but 50% useful.
