Patrick currently has the Crobidoll Ys head but it's quite yellow. As it happened, someone in the Mirodoll discussion group on the evil Facebook asked about the combination of a Mirodoll 68cm body and an Akagi Ban head, and I so happened to have it.
Since Patrick has only appeared in two photostories (Prom contest and something silly a year ago) he's not yet an established character so changing his head now won't be a big deal. That said, I really like this head. It's pinker, so it fits better than the yellow Ys I have now, but what I really like is the mobility. It can really go side to side and front to back. More than any other doll I have. Plus I think it's super cute. So anyway, I might slap a face-up on this poor ol' head and see what he looks like.
