SDCC Walking Dead Hershel's Farm Minimates

I might have to add these to my Walking Dead Minimates collection. These special Hershel's Farm Minimates were from the 2013 SDCC San Diego Comic-Con. It appears that when the walkers were shoved into Herschel's barn, they armed themselves with various farm implements. I don't quite remember them carrying the tools out of the barn when they were slaughtered. The set comes with four toys.
