I busted up Yoda's Flying chair for the ball on top, and the satelite dish on the back.
The body is a WWF monitor from a set. I cut the handel off the top.
The legs I cut off of that cantina guy, with the pants over the fake legs.
The gun is from the POFT2 Stormtrooper rifle.
Some various paints, brillo, and some drybrushing and you have this little piece of crap.
