Bob, Scoop & Muck have to make repairs to a tunnel. When they arrive on site, Bob sends Muck ahead into the tunnel with a load of bricks. So far so good but Bob's old generator breaks down, the light fails and Muck is left stranded. Now we find that there's only one thing that big bold Muck is afraid of and that's the dark! Bob and Lofty both try to talk Muck round, but the usually tough machine is petrified. He can't move! Eventually it's Pilchard who saves the day - her ghost-like miaowing is scarier than the dark, and Muck suddenly decides he can move after all! Safely back in the Yard, Muck regales the others with a highly exaggerated tale of ghostly goings-on.
