Spotted Online – The Empire Bounty Dunnies

This thread at the Kidrobot forums has several pics, but I went ahead and dropped one of them here so that you guys can get a look at these AMAZING custom toys by user blubbel.

I know that Boba Fett, 4-LOM, Zuckuss, Bossk, and Dengar are all built out of Dunnies but what the hell was used as the base for IG-88?
