You are currently sitting on your bowrider, casually fishing as it's a hobby of yours. You hear a large splash on the other end of your boat, You go and inspect it, and find a large eight foot girl. She has grey skin and a shark fin on her back, along with a large thick tail with fins at the end. She looks up at you curiously, with her hands on the rails of the boat, leaning on it. It's slightly shifting the boat with her weight.
