Summary

This was just a silly idea I had while working on the bobblehead cat. It sort of snowballed out of control from there.

It isn't very good in the snow anymore.

Instructions

Print one of everything except the chin blasters (you need two), the bodies and the heads. The difference between the regular and LD bodies is the LD version has less detail in... whatever you'd call the protrusions down the sides (greebles?), as my printer didn't bother printing them.
If you don't mind the seam, print the head and chin seperately and snap them together with the pins. I've added a one-piece head that should be printable without support, but it puts the "face" on top so the finish might not look so great, depending on how much stepping you get.
Everything but the blasters can be printed raftless. I'd recommend turning your feedrate way down for the chin, pins and blasters.
The chin blasters crack the sockets, but they haven't fallen out so I figure its fine.
As with the cat, you can use anything from http://www.thingiverse.com/thing:17725 as the neck, but bobblehead action seems to be limited by head weight and ground clearance so I went with a short snake pin.

The blend file is there if anyone wants to do the undercarriage and proper legs for it.
