Book excerpt: Every morning Digger Dan and his friends go to Digger Day Care. But this morning is very special. The Mice have a building plan and every little vehicle has their very own task to complete. Leo the Wheel Loader lifts a heavy stone. Digger Dan digs and digs, piling sand higher and higher while Theo the little dumper truck carries a load of pretty balloons and Carley Crane helps wherever she can. When the big project is done, everyone is so excited to see their big, beautiful creation! Can you guess what the little vehicles built?
