When Porridge was a wee kitten he toppled into a tin of tartan paint -- which is easy to do and not so easy to say. Now he lives by Loch Loch with the quirky McFun family: Gadget Grandad, Groovy Gran, Dino Dad, Mini Mum and the twins, Roaring Ross and Invisible Isla. Porridge and the twins have been dragged to Loch Ness where Dino Dad is hoping to dig up some pre-historic bones. But when a magic wishing bone transforms Dino Dad into a real-life dinosaur, he's mistaken for the Loch Ness Monster and captured by a Nessie-hunter! Can they prove Dino Dad isn't really Nessie and save him from the dastardly Fergus McFungus? Join Porridge and the twins on this dino-tastic, Nessie-riding romp around Scotland's most famous loch. What a Loch Ness mess!
