Sorry to say but this is exactly what you don't want to see. It means the snake is stressed out and trying to find adequate shelter. If you want a snake that is out climing around all the time, I would recomend a different species. A happy ball python will spend probably 90% of its time in its hide. A BP that is constantly climbing around is stressed, and a stressed BP turns into big problems.
That is such a beautiful setup. If it were me, I would stick the BP in a tub and put a kingsnake in that tank instead.
