I have never made a unit filler before (such things were not at all common when I was collecting Games Workshop Warhammer. Now the seem all the rage, particular in big units. I am making this mobile idol of Mork (or perhaps Gork) for the Bloody Bones Tribe to push about in battle. I will have some more orcs pushing it and milling about the wheels. It will add two ranks to the unit making i a unit of 36, although there will be only about six figures on the base. I will probably only use it in large 3000 point games.
