When I finally decided to bring out all of my Transformers from my parents' attic a few years ago, I found Grimlock minus the shell. Bummer. Since I'm still technically banned from purchasing whole Transformers for a bit, I decided to look on eBay for his shell. Lo and behold, I found it. Finding Pretender shells is pretty easy. A lot easier than I would have imagined.
I love how chubby the Classic Pretender shells are. It's like Grimlock got a little crazy at the all you can eat Energon buffet. Still, it's nice to complete him.
