Bob and Wendy have attended a lunch at the town hall. They leave Scoop in charge of finishing the Mayor's garage. However, when Mr Bentley arrives the inspect the work, Scoop gets too big-headed and accidentally crushes Mr Bentley's gold watch! Meanwhile, the Mayor presents Bob with a gold watch of his own.
Mr Bentley has organised some town improvements. Wendy is to turn an old railway line into a cycle path and Bob is to turn an old rubbish dump into a park. Lofty has been equiped with a magnet to remove the old rails. Lofty's magnet comes in useful to search for Mr Bentley's pen. Bob then recycles the old sleepers and rails into a park bench.
Bob brings Scoop and Muck to the yard, both machines covered in mud. Bob decides to give them a wash down. But Muck doesn't want to be washed down - he loves being mucky! Just as well when Travis gets stuck in the mud and Bob, Muck and Dizzy have to go and rescue him. Later on Muck, Dizzy and Spud have a mud fight.
