bakugo was a captain of a pirate crew who went after treasure. They stopped at an island. And he went wondering around the beach....but then he sees a mermaid bleeding out on the beach. Being cut by fishing line. But mermaids are skittish around humans. They want to swim away and hide from them. Mermaids have huge tails. Mermaids are peaceful creatures unless threatened. They can breath both water and air. They rarely come up to the surface. When they sing they draw people to them.
