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.

The sheriff needs money to bribe driving instructor Snooker to let John pass his driving test and sees his chance when Rose hi-jacks Marian's suggestion to hold a Eurovision-style song contest.

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.

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.

Everyone is feeling the pinch and the sheriff sacks Gary to cut costs. The sheriff is almost sacked by the king but avoids it and,along with remaining guard Graeme, takes a trunk containing the king's gold to the bank. Fearing attack they dress up in an elephant costume but the trunk breaks off it and Graeme, mis-hearing the sheriff, takes the elephant's trunk to the bank and leaves the money behind.
