The award-winning series returns with an all-new cast of children. In this episode technology takes over the nursery, as the four-year-olds get to grips with the classroom of the future. How will tablets, robots and other gadgets affect how the children play? And what is tech doing to the bodies and brains of this generation of digital natives? Gadget-obsessed Arthur gets the opportunity to meet a cutting-edge robot, but will he view his new friend as a piece of technology or as something more human? Iris, Na'Shae and Keira are each given their own tablet to use, but how does it impact on the girls' friendship and the way that they play together?
