Bob gets busy on a smaller job than usual. Scoop is digging when he spots a wiggly worm in the earth in his digger. He puts the earth with the worm safely to one side and carries on digging. In each load of earth that Scoop moves, the cheeky worm keeps appearing. Bob comes to check on Scoop's work, and Scoop explains about the worm. Bob laughs and points out to Scoop that there's not just one worm, but lots of worms.
