Make Baron and Dragon be sleeping until attacked

I kind of find it weird for dragon and baron to be just be chillin in the exact spot doing nothing even when tasty champions walk up to them. I mean the dragon's wings must get get tired? So why not have them sleeping until someone attacks them? And when they wake up they unleash a bloodcurdling roar to accompany their anger and ferocity as they attempt to defend themselves.

Or it could be something else besides their mostly static positions, like devouring a teemo carcass. Really its not in any way needed but i think this would be cool.
