Am I the only one who notices this? In all of PaRappa's games (And the Anime) PaRappa wears a red-orange beanie, a light purple tank top, and has brown eyes (Well, his eyes are solid black in PaRappa the Rapper 2) while on anything else PaRappa related (Such as box art), he wears an orange beanie, an aqua blue tank top, and has solid black eyes. Not only that, but he usually has a big grin, while in the games he never even shows off even a little bit of teeth.
