Review from Amazon.co.uk: Bob the Builder's fantastic fabric play tent is for parents and kids alike! Both mum and two small ones managed to fit into our tent to read stories to Scoop and Dizzy, play games and even eat dinner. Bob the Builder fans will fall in love with this sturdy fabric playhouse: just let them climb inside and let their imaginations loose.
