Loved Chirpa as a kid... He and Wicket were just all kinds of fun to someone my age who loved Ewoks that much. Still have my Chirpa hanging aruond here somewhere, incomplete now.
The great thing about the Vintage Ewoks is they actually fit in with the new ones to a degree too... Nice filler, though at this stage Hasbro's made a lot of Ewok army builders too, at this point really. If nothing else, lots of fodder.
The weapons of the vinty's were nice too... crisp detailed sculpts, nice hoods that were easy to remove if not a little bland in color.
The modern Ewoks are awesome though... diminutive, and the size perfect for a Stormtrooper to be posed chucking one across the room like he's dwarf tossing at a frat party. Or to have a few swarming a trooper and dragging him down for a fuzzball forearm beatdown.
Chirpa was kind of the onset of the diminutive Ewok style in terms of scale, right? Tons of detail on the headdress, and nice paint aps to highlight the sculpt. That's back when Hasbro did stuff like that routinely of course.
The bonehead staff features the same nice sculpting and paint aps...
To me though, the greatest update, other than the scale maybe, is the knife. I loved that! Tiny accessory in a functioning sheath? That's pretty great.
Besides maybe a hyper articulated update, which I completely do not expect to ever happen, he's pretty great. The only real thing I'd like for him is a throne to chill on, actually. He suffices to me... He's not as articulated as other fuzzballs, but he's good, and I'd prefer the warriors were the ones articulated better anyway and I'm ok with Chirpa now and not really caring if he's ever redone... though I'm not hyper particular on each Ewok's scale being done exactly right. To me, I like them just being done smaller than they used to be.
It's sort of like astromechs. I was happy with the old BAD-ish scaled ones, but Hasbro saw a need to make R2 shorter and I'm not into that terribly I guess. Ewoks, I'm happy where they're at now, even if they're a hair off now and then.
