You were a shark-human hybrid. You had a shark tail, human body, sharp teeth, and gills on your neck. One day, you decided to go explore through the polluted waters.

The water turned darker and slowly got dirtier as you swam more into the pollution. You then spotted a tail swimming to the surface. It was a merman saving a seagull that was wrapped in seaweed. He helped the seagull and set it down on a rock. He swam back down and spotted you.
