Just a hole?

Jack and I went to the woods today hoping to see Drucilla and Murray from the Stone Tribe, but we couldn’t find them. Jack followed their scent to a hollowed out area in a log and told me he thinks they’ve gone inside. Inside? I told him it doesn’t look large enough for anything to hide inside. Jack took another sniff and said he was sure they went inside and he was just as sure that they hadn’t come back out. I bent down to take a closer look and could see that the opening was large enough for the Stones to pass into, but it was not large enough for them to hide inside. I grabbed a stick and poked into the hole. Surprisingly, the stick was almost a foot in before it hit the end of the tunnel, but at that point it felt solid all around and there were no Stone people hiding from my probe. Jack thinks it might be a corridor or a secret tunnel and that my poor human senses are too dull to find it. I couldn’t argue with that and there didn’t seem to be much point in hanging around so we went back to the path and hurried the rest of the way around because rain clouds were moving in.
