Bob has been working all night laying lino. Wendy takes Muck and Dizzy to clear a blocked drain, telling the others to keep quiet while Bob sleeps. Spud arrives, looking for someone to play chequers with - the Machines improvise a game using traffic cones, tyres and an off-cut of the chequered lino as a board. Meanwhile Muck is spooked by the gurgling noises, which emanate from the drain - Dizzy convinces him this is a 'drain monster'. Once Wendy has pumped the water into a container, she uses drain rods to shift the blockage, but they won't do the trick. She'll have to dig up the road, but discovers her ear-protectors are missing. Muck happily takes her back to the yard, where the chequers game is proceeding noisily. Reminding them to be quiet, she returns to find Dizzy listening to the 'monster'. One particularly loud gurgle makes Muck knock the container - the water pours into the drain and manages to clear the blockage.
