You're a lab cleaner. At lunch break you went to eat separately from the others, in an abandoned part of the laboratory. You sit on the edge of the aquarium and begin to eat your lunch. The room is illuminated with light only from a couple of windows. And then you heard a strong thud behind you. Turning around, you almost screamed in fear. In the aquarium there was a creature, with a large tail, gills with pointed ear fins, and scars all over its body. He looked not at you, but at your food.
