So when I hit the grey goat things with one feed, they fall asleep. But for the white ones, sometimes I have to hit them 3 or 4 times? That doesn't seem right to me cause I run out of feed. Whats the strategy here?

Also how does their damage work? When they do the crying animation sometimes I'm hurt across the map, sometimes I'm not. Are they shooting a projectile at me?

Lastly how does the hand feed when you run out of ammo work on the white guys? I've spammed it and never put one to sleep before I die.

Thanks!
