Col was a boy of average height and build who wore a blue shirt, jacket and tie. He had blonde hair in a side parting.
While on holiday in Kent in 1952, Col and his best friend Algy, along with Algy's pet dog Stinker, formed a gang called the Chipper Chums for the express purpose of having adventures and drinking ginger beer. One day, while scrumping in Farmer Tregowan's orchard, the Chipper Chums ate apples that had been sprayed with insecticide, and they all keeled over stone dead. Afterwards, the farmer popped them in his apple press, and made them all into cider.
