If you haven't taken a shot at modding a Munny (by Kidrobot®), I highly suggest you contribute to the incredible community of Munny artists. I had a blast doing my first one, and I plan to do many more in the future.
I title this first one Heavy Metal Munny. It was for a friend who is a huge "Lamb of God" fan. I used a combination of Super Sculpey®, screws, tin foil (for armatures), markers and acrylic paint to make this Munny.
