I go an idea that I don't know how difficult it would be to impliment. I'd like to have a living trophy room. The trophies would stay on their pedestals and not be killable but would have their normal animations. Bears for example would stand on their hind legs and roar occasionally. Just an idea but how would I go about it?

What if you place them on the pedestal and surround them with a collision plane.

You can tick the immobile box in the race menu, remove the aggression, set to help no one but not cowardly. That should keep it still.

I think bears only stand on their hind legs as part of their combat animations. My mod features a pet bear and he just sleeps, stumbles around and growls sometimes I've yet to see him stand on his hind legs.
