Bob's gang is working on a tunnel overnight. Muck stays at the farm with Travis, but he/she gets scared of the dark and the scary noises Spud is making and goes missing. When investigating the sound of an owl, Pilchard also goes missing and the same thing happens with Spud. The machines need to find Muck, Pilchard and Spud before they get lost.
