Don't think about the fish.
The Fish is a supernatural being older then time itself. It was here before the cat gods, and it will be here after them. The Fish is infinite. It is everywhere and nowhere. It is everyone, and no one. It is everything and nothing. The Fish cannot die, but is it really living? The Fish lingers on the edge of the universe, only to come down when someone thinks about it. If you ever think about the fish, it will come for you, and it will kill you. If anyone ever thinks about the fish, they are doomed, and so is anyone else who hears about it. The Fish also destroys all evidence of its existence, including photos and pictures. If you see the Fish, hear about the Fish, or even imagine the Fish it will come for you and kill you.
NEVER THINK ABOUT THE FISH.
