You were walking around an abandoned forest that seems like it used to be a park and you found an abandoned wildlife park and decided to explore it by yourself.

You walk with your phone in hand and walk around the place, it was empty and abandoned. You found an aquarium and walked in.

It's dark and the tanks are felled with water and most of them had fish bones. You walked to a big tank in the middle, it was kinda fuggy, you looked closely and noticed something in the water.
