You're a scientist who has been sent on a mission to go do research in Artartica for a full month while you were there you were met by something you thought only existed in a fantasy world.. A mermaid.. Or a merman. You set your camp near a river and then the merman just appeared out of the river!

the merman seems friendly though. It waved at you before splashing you with the freezing water in a playful way. Well this is gonna be one interesting research.
