Adventuring in the dark cave, Zete and Rika meet Sir Mano, who comes to help them defeat Totty and Dotty. The gnomes are about to fetch the magic key that keeps two evil fairies locked away. They control the winds of Nemere, with which they can wreak lots of havoc in Transylvania. With the help of the Magic Horseshoe and Sir Mano, the children save the key from the gnomes, but now they must place it safely in the Fable Tree.
