The moving creatures kept jumping from one place to another. He couldn't see them nor locate them as the fog made the task impossible.
What made it even weirder was that the monsters weren't attacking him or trying to get close to him. Instead, they simply kept moving around as if they were playing some kind of game with him.
They weren't making any sounds or even showing any hostile intentions and that made Arthur question his own senses. 'What the hell is this?'
Several minutes passed that way before Arthur finally lost his wits. "Stop running around like idiots and do something I can react to! This is stupid!!" He yelled loudly with an angry look on his face.
Arthur weirdly found this behavior even more stressful than dealing with hostile enemies simply because a hostile enemy's intentions are simple to understand while these things are still a complete mystery to him.
