Elephants Don'T Lay Eggs

When Zoe finds a strange object in her back yard, she rushes round to Raheem's house. He comes to look and declares that the object is an egg. Because it is so big Zoe says it must be an elephant's egg. That night Zoe and Raheem see a large lumbering animal coming to look for the egg, but it is not an elephant - it is a brontosaurus.
