Never allow a Bearded Barfing Beast to sneak up behind you. If you do, things will get messy.
I don't want to give the impression that Bearded Barfing Beasts purposefully barf on humans though. That is not the case. They barf indiscriminately, on whatever happens to be in front of them at the time. So if it happens to you please don't take it personally.
