More idle/giving-live animation

I think that the game would feel more life-like if some creatures would have more idle animation. I'm pretty sure that everyone loves new animations.
Here are some of my thoughts/ideas:
-(idea) Durring full moon idle hounds could start howling. Players would be able to hear howling no matter how far thay are from hounds, something like a full moon ambiance.
-(idea) Spiders should act more like a mini vicious predator: turning their body/heads around lookinig for prey, cleaning their teeth with tongue or leg. And I think that giving them blinking animation, that typical spider blinking animation would fit just right.
-(thought) Maybe some sort of shadow transformation for monkeys and ruins statues other then just Mr. Skits appearing, covering them and boom now they're in their shadow form.
-(thought) Idle Treeguard shaking off some leaves off their arm or something like that.
-More harmless shadow creatures. Yep. If someone is insane they deserve a: drowning shadow hand in the sea/ponds. Weird shadow people looking at them from behind a tree or a rock and then hiding when player gets too close.
