Another classic picture book from the Smarties Prize-winning partnership behind Tadpole's Promise"On top of a mountain there lived a fat mammoth. Down in the valley there lived a thin caveman. The caveman was hungry. Very, very hungry. He saw the mammoth and licked his lips." Fed up with eating seeds, fed up with eating weeds . . . a mammoth can start looking pretty delicious to a hungry caveman! But a mouthwatering Mammoth Pie turns out to be more difficult to come by than the caveman could ever imagine.
