Every time I post a chipmunk pic, I get concerned that people will think it's just clever editing. Well, that's just not the way I do things; I capture a real, live moment that's right there in front of me.
It wasn't hard to get Billy to approach Chewbacca; all I had to do was slip an almond into the action figure's pre-moulded hand. I used a paring knife to whittle down the end of the almond so that it would slip cleanly into his grip. Billy would then go right up to Chewbacca and pull the almond out of his hand. :D
