A rival gang arrives in Worksop, led by the Australian Beast of Bolsover and his nephew the Nuisance of Nuneaton. They refuse to leave unless they are paid twenty five gold pieces or someone defeats the Beast in a fight. The merry men capture the sheriff, who is suffering from amnesia, and when John refuses the ransom, Marian persuades the sheriff that he is one of her gang and gets him to fight the Beast.When Rabies accidentally knocks Robin's wardrobe out of a tree it falls on the sheriff,who remembers who he is as a result and arrests the Beast and his mob.

Fed up with the merry men's sexist attitudes Marian quits the gang and teams up with Rose, who is selling home improvements, including a flat pack extension for the castle in which John can put Guy's many toys. Rose, of course, is planning to deliver Marian and her men to the sheriff and lures them into the dungeons. However Marian escapes and ends up in the extension, which promptly collapses. Feeling ashamed of themselves the lads invite Marian back as their leader though Rose prefers to stay in the dungeons rather than become their au pair.

When the villagers catch colds the sheriff takes them to the seaside but, once there, forces them to build him and the king a holiday camp in time to celebrate High Forks Night. This commemorates a failed attempt to kill the Royal family which caused forks to go flying up in the air. The merry men are holidaying nearby and so Marian dresses as the food inspector, allowing her and her gang to infiltrate the camp, where they tell the villagers to feign having the Multi-Coloured Pimple Plague in order to escape.

The gang are suffering from insomnia and keeping everybody else awake so Gladys gives them a cure, Sleepy Cake, though it only succeeds in making them look like the Beatles. Gladys says her father knows a cure but he is a prisoner in King John's castle so the merry men set out to rescue him.They get him out, though not only do Marian and Robin get caught in the process but the old boy wants to go back to the castle as he is used to being a prisoner.
