Panic ensues when a comet appears over Worksop, causing Snooker to fall off a ladder and get covered in glue and leaves and King John to fear an alien invasion. He determines to build an arsenal against it but steals all the villagers' clothes to sell in order to provide funds to build it. Taking advantage of the fact that Guy told her about his invisible alien chum Plopbop, Marian presents him with the leaf-covered Snooker and, having told him this is Plopbop, she gains access to the castle which the merry men,dressed as aliens, invade to retrieve the villagers' clothes. A little girl called Hayley has been sick at the appearance of the comet and Marian decides they will commemorate its sighting by naming it 'Hayley's Vomit'.
