Pocket Pirates. The Great Cheese Robbery

In the junk shop at the end of the street is a dusty old ship in a bottle. And when the world isn't watching, a tiny pirate crew come out of the ship to explore. They aren't much bigger than a matchstick, but they have a HUGE appetite for adventure...
When the skirting-board mice kidnap Jones, the ship's cat, and ransom him for cheese, the Pocket Pirates spring into action. But to get the cheese, they must venture to the freezing cold place where it's always winter ... The place called Fridge. Can the Pocket Pirates survive their perilous journey and get their ship's cat back ...?
