The sound had been a mug hitting the floor, though thankfully it was empty and also didn't break. It had fallen from nerveless hands, as Gobo was in a heap nearby. One leg was folded under him and the other a bit out to the side with his hips, up in the air, leaning as if he were about to fall over. One arm was over the back of his neck and the other toward the handle of the mug, and his snout was pushed at an angle on the floor. All in all it looked like an intense collapse... in which he was snoring oh, oh so gently.
