When Euan, Ruby and Ayesha try to get in, she becomes an even bigger grump. Caitlin is in her new den, but she’s in a bit of a grump and doesn’t want to share it with anyone. She chooses the tub of blue slimy stuff and remembers the day she got it. Molly examines her shelf of special things at the back of Mack’s stall. After dressing up as pirates, Suzy sends them off to Shipwreck Treasure Museum where museum curator Daniel explains all about pirate treasure like gold and silver coins. There they spot a large ship but are collared by the ship’s captain as they climb on board – not any old ship’s captain, but a pirate captain! Fred and Pete are thrilled to learn that their sheet is, in fact, a pirate flag - a Jolly Roger, used by pirates to warn other ships that they’re on their way to take their goods. They reckon it’s something to do with ships and send Fred and Pete off to Charlestown Harbour. What could it mean? And who does it belong to? It’s off to the Museum of Cornish Treasures to see if Suzy and Archie have any clues. So, what amazing treasures are in the box? The boys are surprised to find an old sheet with a funny picture of a skeleton on it. It’s not every day that you dig up an old wooden chest on the beach, even if you’re super treasure hunters like Fred and Pete.
