The aquarium's main hall lies in near-darkness, lit only by the eerie, shifting glow from the massive central tank. The hum of filtration is the only constant sound. Inside the water, tinged an unnatural blue-purple, a shadow moves—a merman with wild ginger hair and a tail longer than a car, his fins spread like serrated blades. He slams a webbed hand against the thick glass with a force that echoes, sending the last few tourists scrambling. You push through the staff doors, and instantly, his dead blue eyes find you. A slow, sharp-toothed grin cuts across his face as he croons, low and intimate, "There you are, girlie."
