I am sure that P would be very happy to have me discuss his GPBs online because he is so freaking proud of them. As I said, in the late summer they usually contract a LOT - like they are maybe a quarter their normal size and you can actually see and feel them in his lower abdomen. Then in early winter they start to grow - first fuzzy, then suddenly they become naked and alarmingly, um, human looking - pinkish - and then from there they get larger and darken until they are dark purplish black where they stay until they disappear again. The degree that they change is amazing, really.
