This set of six mini-landscape books will turn children into avid collectors. Each book is based on the exploits of one of Bob's machines - Scoop, Muck, Dizzy, Lofty, Travis and Roley. Together the six create a charming library. Bob and the team are working through the night to replace the lights in a tunnel. Muck persuades Bob to let him sleepover with Travis in his shed in the countryside. But he gets scared when he hears funny noises. Muck rushes off back to the yard. It's Spud making silly noises, but Spud soon gets a shock of his own and Pilchard, Spud and Muck all end up charging around the countryside. Bob manages to find them all and has a great idea - he puts the big night spotlights on Travis' shed so Muck isn't scared of the dark any more.
