I migh be onto something, maybe not... See this furry? Now look at this; See anything?if not, I'll point it out; This furry looks awfully familiar; To this one; Maybe it's just a coincidence, maybe I'm going insane, but if I didn't know any better, I'd say one is a copy of the other, maybe it was traced, or stolen, maybe not, But for them to look that similar... that doesn't just happen, or does it?
