I'm with Scott for the most part... We've got pretty much every Chewie we could want perfect. I would go a step further though, and think it'd be great if they re-issued VOTC with the Cloud City Escape Chewie's head as an "ANH" version.
But beyond that, then I totally wish they would try a real fur Chewie... If it were really special I dare say I would go and pay $10 for it if done right.
I think it'd be funny at least... "Fuzzhead" Chewbacca.
BTW Beth's comment about rolled in brown sugar has me cracking up. Never thought of that, but yeah he does look like a tasty breakfast treat.
