When farmer Brown's away, the animals will play-and the result is a hilarious, laih-out-loud story kids will enjoy reading again and again. Bess the cow and Morris the sheep each decide to take a ride on the farmer's tractor, but soon find themselves zooming around the farm, out of control and wreaking havoc wherever they go. As kids read the story, they can be part of the action by moving the colorful tractor along a path and trough the pages of the book - just as if they were riding on the tractor,too.
