OMFGs! XD I never even saw that before (and I do have the camera mod lol), so just checked on it in the game. Really odd lot, but very interesting.

I wonder how do sims even get there! train or brooms!? lol (I can see a witch living there, for sure)

And, btw, don't know about extracted skulls, but xanathon has a skull lamp at mts
