Have you ever watched the old cartoon Spiderman? Old school, none of this newfangled shit. There was a character who was part human and part green lizard thing. One of his arms would grow and be green lizard thing. There's this guy I see around the hill who reminds me of the green lizard arm scientist. Why, because he is tattooed all the way down across his hand in what appears to be mostly green scales, although there are other pics. But just the one arm.
