Robin goes to Worksop to buy a Chinese takeaway but finds he has been given only one bean-sprout,which he throws away in disgust. Gary and Graeme have been sent to get a 'fur' to clothe Guy with, but come back with a fir tree by mistake, which is discarded in the same place as the bean-sprout. Robin believes this is just like 'Jack and the Bean-stalk' and he climbs the tree, ending up in the Royal dining room, where he steals the king's takeaway for the merry men.

Rabies falls asleep, causing the outlaws to miss an ambush but, on waking, he sees a boat purchased by the king at a boat show. The merry men steal it and take it to Scarborough to push off the cliffs, in the process landing in a parallel universe where nice princesses Rose and Guya have been usurped by a witch who looks like Gladys and an ogre who is a ringer for Snooker. Rabies becomes a hero when he steals Gladys's magic wand and turns her into a box of tissues and Snooker into a set of place mats.

After the castle is attacked King John decides to abdicate in favour of Guy. He goes off to the outlaws' hideout where Robin, hoping the king will leave him money, entertains him. However the king eats the merry men out of house and home to Marian's annoyance.Guy is an extremely childish ruler and the sheriff is tired of his infantile demands. He thus forges an unlikely alliance with Marian and the merry men, whereby they use giant puppet dinosaurs to frighten Guy into abdicating. However John likes it so much in the hideout he refuses to leave.

King John hires a man who is Robin's exact double to do bad things around Worksop, thereby discrediting him and the outlaws. However he is rumbled by Marian who persuades him to work with the merry men and a dead ringer for the sheriff and make Robin popular again. With the job done the look-alike sheriff gets somewhat carried away and heads to the castle to attack King John, making life difficult for his double.

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.

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.

Marian is unsettled to see her sneaky ex-schoolmate 'Rotten' Rose Scargill cosying up to Robin and tells Rose the reality of their situation as outlaws. Rose then betrays both Marian and Robin to the sheriff and they are caught and imprisoned. From the window of the torture chamber Robin sees Marian appearing to be friendly with Guy. In fact Guy has a crush on her and is trying to force himself on her but Robin misunderstands the situation and believes Marian has betrayed him.

Rabies falls in love with the strongest woman he's ever seen, and it's up to the Merry Men to ensure he gets his dream girl. Unfortunately, she's also the target of the Sheriff's scheme to get rid of King John's annoying nephew, Guy.

Due to be executed with Marian, Robin realises that she did not betray him when Rose reveals that she wants his body stuffed for her Robin Hood Museum. Fortunately the other merry men attack, under cover of the rubbish bins, and save Robin and Marian, who leaves Rose to the tender mercies of the lecherous Guy, tied up in the torture chamber. Robin is ashamed for what happened but Marian persuades him to stay with the merry men.

The sheriff has a giant jelly baby in the likeness of King John made to give him as a present but the merry men steal it. In order to cut his losses and find another gift for the king, the sheriff tells the villagers that it is the festival of Bloopie when they must give presents to Father Bloopie, alias King John. When he has them all in the castle the sheriff plans to keep them until he gets presents from them but they are rescued by the merry men, using the jelly baby as a battering ram before they eat it.

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.

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.
