Jumbeelia, a girl giant, loves the stories of the iggly plop who climbed up the bimblestonk and was chased back down again by a giant. Growing her own bimblestonk, she climbs down it and finds a whole world of iggly plops - our world, in fact, where Colette, Stephen and Poppy are very surprised to find themselves collected up into a bag and carried off back up the beanstalk. So begins a wild and wonderful tale of how three children escape from an overenthusiastic giant girl, her very-pregnant giant mum, and her very nasty adolescent giant brother.
