The two of you head to a nearby doorway, and the creature continues to lumber ever closer. As the creature draws nearer, the static sound coming from the eye grows louder and louder. In short time, the creature reaches the part of the road you were standing on, and the static from the eye grows so loud you're sure the creature must be able to hear it.
But it does not, and continues down the road. As it draws further and further away, the static decreases in volume, and by the time it has passed out of sight, the static is inaudible.
If you would like, make an IQ roll.
