It's Scratch's first day, and he's a bit scared. Today they are helping David Mockney by working on the Fixham Museum gardens. However, instead of giving Scratch a job to do, Bob asks him to watch everyone else - you can learn a lot from watching! Scratch spends the day watching the other machines but still isn't satisfied - he wants to do something! He decides to practice digging by himself. Whilst digging Scratch's bucket hits something! Hes found treasure! But Scratch is too scared to dig it up himself - what if he messes it up? When Scoop and Muck arrive and begin squabbling over who should dig up the treasure Scratch decides to take charge! Bravely, he tells the diggers that he is the best digger to get the treasure! Concentrating hard, Scratch remembers everything hes learned from watching the other machines and manages to dig up the great Mockney "Mung Vase" made by David Mockneys Great, Great Grandfather!
