Synopsis
A cold virus (or The Plague) is sweeping through Worksop. Even King John catches it and decides he needs a break by the sea. The Sheriff rounds up the peasants and gets them to build a seaside holiday camp. As luck would have it, the Merry Men are on holiday not far from the new camp and devote their energies to infiltrating it and stopping the forced labour so that everyone can celebrate High Forks Night.

Maid Marian and Her Merry Men | S4E7: Journey to the Bottom of the Forest
Rabies is lazy, so much so that many of the Merry Men's plans simply do not work because of him. However, the robbery of a battleship and its subsequent launch take the Merry Men to the parallel universe of Engyland, where Rabies' arrival has been eagerly awaited by the good people of Workflop, particularly the Nottyman, to save them from the wicked witch.

Maid Marian and Her Merry Men | S4E6: The Nice Sumatran
Marian attempts to scare off King John, who is actually scared off, surrendering his crown to Guy. He takes refuge with the Merry Men, who reluctantly decide to follow the example of the Nice Sumatran towards unfortunate rich people and agree to let him stay. However, relations with the new guest deteriorate and Marian realises she has to scare Guy into surrendering the crown to King John again, which requires an unlikely alliance with the Sheriff.
