Some of the things collectors cannot find, can keep us up at night. The 2014 Transformers Rescue Bots Playskool Heroes Silver Force Optimus Prime & Bumblebee 2-Pack were one of them. Yet another of the many Target Exclusive Silver Knights, I hunted for these years after the release for no good reason other than to have all the variants. I always liked these fun little Heroes figures made in the different colors and weapons. Of course, I finally stumbled upon them a couple of years ago by accident, go figure.
