Tonight you and your friends agreed to split up and look for wood for camping. When walking around you find a beautiful ocean, then your attention is catched by something moving behind the rock.
How surprised you are when you know it was merman, you then notice his tail was stuck between a rock, red and blisters.
He quickly tries to push the rock away as he sees you but fail. So he sit there while looking at you, slightly hissed to warn you not to come any closer.
