Synopsis
The Merry Men need to build a bridge to cross the river in order to steal from the rich, a task which is not made any easier by Robin's literal adherence to Marian's instructions. Meanwhile, King John's uncle, the Duke of Dagenham, has died, leaving him only a hot water bottle, which the Sheriff is to sell for a grossly inflated price. Of course, the contents of the bottle prove a nice nest egg.

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.
