I've noticed Goblins always say Pshhh... Shkohhh... at the beginning of most things they say, and I've started to wonder about it. As far as I know, there are no voiced goblins. I've come to imagine that this is supposed to be a radio static noise, such as when someone presses down the talk button on a walkie talkie.

Or is this some sort of throat clearing goblins do?
