"Gammelnok" gathers three of the remaining Nisser (Hansi, Günther, and Fritz (all distinctly German-sounding names)) and sends them off to Denmark, to find the old Nisse cave where the key to wind up the music box is. He gives them "The Big Book" to take with them, an ancient tome that contains the answer to any and all questions, warning them to take great care that it does not fall into the hands of a Nå-såer. If this were to happen, all would be lost. They are also warned to take care, as the Nå-såere nowadays have taken the appearance of normal humans, but when they consume alcohol, they regain their original appearance, with fangs, and thick-rimmed glasses. The three merrily set off, and this is where the first episode begins.
