Hive animation when low on health

<div class="IPBDescription">(reposted from getsatisfaction)</div>This one was inspired by our old mutt unfortunately, but when the hive is on its' last legs and low on health, how do you think it might look if it starts to "breathe heavily" / "gasping for air", contracting a bit before returning to full size, as a visual showing it's fighting for life (imagine an asthma attack or similar)
