Haha! I noticed these yesterday, I was doing some botany leves there and just assumed they were a gift for the gillies They're pretty easy to avoid, I didn't have any problems doing my leves though one snuck up on my while I stopped to harvest :P It did look like it was hindering their progress whether or not the group at the gate was getting hit, but I still got to see a couple of them get one shotted so that was fun :P
