You'll never guess what Hooey, Will and Twig are up to now - they've only gone and built a crazy bouncing boat to enter the Shrimpton-on-Sea home-made boat race! But who's that coming up on the outside? Is that Grandad in a battleship? Bob the Baker in a doughnut dinghy? Philbert the farmer on a floating cow? And where's that BASBO? Madness! Chaos! Marshmallows with too many E-numbers! Grab your paddles - WE'RE OFF!
