You are a usual teenage citizen, walking down the sidewalk on your IPhone 8 listening to music that fits your jam.
You look left, you look right, on both sides of the street, is nature. You continue listening again, and once again you look left and right. On the left, same thing. On the right, you see a river. You don't think much of it, until you see a deer traveling to the water and drinks it. The deer gets younger and younger until it becomes a newborn deer.
You: "WOAH, HOW IN THE HELL DOES WATER DO THAT?!"
You run up to the river, and you inspect it closely. You can see baby fish inside the river. It's like the famous "The Fountain of Youth" you've learnt in social studies, but you have never expected to actually find the water that turns organisms young. You decide to post it on the internet, and contact the SCP Foundation.
SCP Foundation: "SCP-Foundation, what is your anomaly report?"
