The ears of the people of Camelot are at the mercy of Princess Guinevere's terrible drumming. King Arthur visits her and offers to buy her lessons, however she's not convinced she needs any. Knowing he'd do literally anything for her she manages to turn it around and Arthur gets tricked, or duped as he prefers to call it, into getting her a Branch from the Singing Oak Tree. In the meantime Merlin is at war with a couple of squirrels, leaving Arthur to accomplish this quest on his own. It's not easy though, as the Oak Tree is being protected by Robin Hood and his merry men and women, who are having problems of their own.
