2x34 - The Adventures of Robin Hood

Robin and Friar Tuck are escorting Marian back home from Ireland, after rescuing her uncle. They are making their way to Cork harbour and a boat back to England, when a storm forces them to stay in the barn of a Pat and Maeve Nolan. When the couple's home is burnt down, the trio are accused and to stop them being hanged, Robin claims kinship with "the little people" – leprechauns, and he and Tuck are given 24 hours to bring back proof of their existence, with Marian as hostage.
