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. Lofty is the star of this adventure. The team is taking up some old railway tracks. Lofty has a very powerful magnet attached to his arm. But he has to concentrate very hard to keep it under control. Chaos ensues with all sorts of unwanted metal things attaching themselves to Lofty's magnet. But Lofty redeems himself at the end when he puts his magnet to very good use and saves the day!
