heh heh heh heh! I want one the boys would love it!
I wonder if its "pop-proof"? Probably not against ours, they have a destruction gene!
£95????? Go to tesco and get a £2.99 yoga ball for that!! You could replace it if it got popped 31 times and still have change (yes yes I AM sad, I just worked that out...)
Try a space hopper instead. Much cheaper and mine love them, can pick them up by the handle things and used to bash each other with it! However my boy was a 17hh lump and did not take long to pop it. Very entertaining to watch though!
