Vanvlak, thanks for the hint, I found his picture! My idea is to use the head as a kind of gate for the terrain in the Haunted House scenario. We'll see, how it works.
It is nice, right? Sorry I didn't get the link myself, am in a bit of a rush this morning.
Haunted houses - should have no roof, but then again the inside is quite visible from either of the large 'doorways' at either end. It is a bit big, though, with about 5" sides.
