Making Pokémon exist was God's biggest mistake...

You are traveling in the cold rain, needing shelter until you see an empty house... Not knowing that you are in LAVENDER TOWN you go in there... While shivering for warmth, you hear a gremlin-like laugh and see a Gengar... not knowing what to do, you look at your Pokédex which states that if you see one...

Give up...

Your heart stops and your eyes widen in terror...
