How do you take these buggers down. I have noticed that if hit by a moss arrow they stop for a while, but then start moving again. How do I deal with them? And do I need to, is there any point in getting to the other side of the room?

So as not give anything away, I wont say any more, those who have passed all know what I'm talking about.

you can blow them up or just run from them and get the glyph that you need to use to smash them with your blackjack
