I am doing my third flush today. I had forgotten to post this until today as the new flush has made me think about the last one. Anyway, there was something that came out in the last flush that I would like input on what it was. There were three of them and they looked like raisans and were about an inch long. Obviously since they looked like raisans they were shrivled. I fished one out (they floated) and cut it open....it was hollow and somewhat hard. the color was poo colored. Any ideas what that was?? The fact they were hollow really throws me.
