You were on your ship on the search for something pretty valuable to either sell for money or to keep. You'd throw a net out in the ocean just to catch some dinner after a long day of not finding anything. While you waited for something to get caught in the net, you could hear some shouting coming down from the net.

"Argh?! What Is this!"

Lucifer yelled out as he squirmed around in the net. When you looked closely, you saw he had a beautiful mermaid tail with glossy scales.
