Norm: If you look carefully at the photo of the whole base, on the left side you can see foot prints. I did that before I took the photos. They are not very deep, but I don't think they need to be.
The catzilla print stays. Tomodachi thinks it belongs there, so who am I to argue with him?
Excellent update, though you did terrify me a little bit waving that marker pen around the models! If that had been me, I'd have put a great big black mark right across that castle. ;D
