When two friends are playing cricket in their backyard, one hits the ball over the fence into the neighbours' yard. Everyone knows the rules - over is out, and you have to go get the ball back. But these aren't just any neighbours - they are dinosaurs! How will the kids retrieve the ball without being eaten? A story of backyard fun (and a sneaky lesson in prepositions as they creep below, between and behind the dinosaurs) from the bestselling illustrator of WOMBAT WENT A'WALKING.
