George the steelworker is working his very last day before retirement. He signs his name on a huge girder that will become part of the [London 2012] [stadium] and his colleagues give a big cheer. But before George leaves he picks up two molten fragments that have fallen from the girder and puts them in his bag. That night, George works in his shed, shaping the two drops of metal into little figures - one for his grandson Jack; the other for his granddaughter Lily. A miraculous surprise awaits the children in the morning - for once unwrapped, and placed on the windowsill, the figures are hit by the beams of a [rainbow], breaking through the clouds. At one, they shiver into life and begin to move. Before long they are attempting to talk and are rushing around the attic room, which is full of photographs and books about the Olympic and Paralympic Games. But this is just the beginning of their wonderful journey of discovery. The rainbow returns and Wenlock and Mandeville - as they will come to be known - set off on its brilliant beams to learn more about the wonderful country they have arrived in, and the amazing sports that will make up the London 2012 Games.
