Pictured above are what we'll call "Boo! Jazz Hands Chewbacca, " "Rad! Teen Chewbacca" and "Adult" Blow-up Doll Chewbacca. In reality, they're advertised as "Deluxe" Adult, "Deluxe" Kid and Inflatable Chewbacca.
Just above we'll call this batch "Chewbacca (in Wicket W. Warrick Disguise)", "Old Man Chewie" and "Fit Bigfoot Chewbacca." In reality, these are the toddler costume, "Collector Supreme" and "Photo Realistic."
Finally, we have this next guy... "I Give Up!" Chewbacca. I'm not quite sure if he's being held up, or just throwing his hands in the air about all of this.
While these costumes don't peg Chewbacca, they do at least look somewhat like other members of the Wookiee species, so if you'd like to create your own version of the infamous Star Wars Holiday Special, now you can!
