S8, E16: When Norman and Mandy get Mike’s van muddy, it looks like their day out to the lighthouse will be cancelled. But when they promise to clean the van (inside and out) on their return, Norman has a plan to keep everyone at the lighthouse until it is too late to do any cleaning, and they all soon find themselves locked out on the lighthouse balcony. In the meantime, Sam and the team have got Jupiter and Venus stuck in some mud and are trying to winch them out – with some very muddy consequences. Back at the lighthouse, Mike, Mandy, Dilys and Helen think they are about to be rescued by Moose but Norman manages to get him locked out on the balcony along with everyone else. As Moose tries to climb to safety he is soon stuck dangling half-way down the lighthouse. Fireman Sam comes to the rescue and when he hears about Norman’s escapades he has an idea…Norman has to clean Mike’s van, but as soon as he’s finished he has to clean Jupiter and Venus as well – inside and out!
