They were at the beach since it was a really hot day and it was really sunny. Most of their day was spent there, so they decided that before leaving home again, they would give a walk around the beach. There was a part of it that had some huge rocks, it was known for being full of crabs and fishes behind all of those rocks. Yet, they didn’t knew that you, a mermaid/man was sit there since the sun already fallen down. You thought there was no one and that it was safe to go out.
