ohhhhh Mr Sully that is soooooooo cool :o I would love to see him jungle gym-ing all over the place! I think he would too as he isn't a shy dude and seems to enjoy perching on his hide every night. I was under the impression that balls get intimidated by space but I suppose if I really kind of clutter the tank it would be really fun for him! Actually, I have all sorts of ideas....
