I know he's too small to be truly lifesize, but it's not TOO far off. I used the bump-n-go Cybermat toy, stripped out it's insides and wheels, filled wheel holes and switch hole, added real LED's (sadly they don't actually light up as the wiring proved too fiddly to do and still fit the tail parts together), made him a mouth and teeth from Milliput and repainted everything.
