Spangles McNasty is horrible to everyone and does vile things like eat cold chips out of bins and pull faces at old ladies. And would you believe it, Spangles has inherited a rollercoaster called the Tunnel of Doom! When Spangles and his bonkers friend Sausage-face Pete go to see it, they realise it's a good for nothing piece of junk. If they want to make any lovely money from it, they'll need to do some hard work. But Spangles comes up with a dastardly plot to get rich quick. Yet again, it's up to local boy Freddie Taylor to chase Spangles on the rickety old rollercoaster and stop him in his tracks!
