Captain Jimmy Cook has made a Top Secret Important Discovery. Even more important than any discovery that the other Captain Cook from the olden days ever made. A real dinosaur footprint! And everyone knows that underneath a real dinosaur footprint will be a real dinosaur bone.
Jimmy has to keep the amazing discovery a big secret because he found it behind a toilet block (that's totally out-of-bounds). That's not going to stop Jimmy and his crew! Once he digs up the dinosaur bone, he's going to be the most famous Captain James Cook in history and not even Ms Fennel will be mad with him.
But even the greatest explorers have problems. Jimmy's are these: 1) Everyone in the school now wants to help in The Dig, so it's just a matter of time before Ms Fennel puts a stop to the greatest discovery of all time and 2) a large smelly cat is sitting in his hole.
But luck is on his side. Jimmy's found a map of the school with a large X on it. And everyone knows what that means -- Treasure! Treasure! Treasure!
Captain Jimmy Cook is about to make the discovery of a lifetime ...
