Wham! Nils knocks an abandoned bees nest off a tree with his propeller. He tries to find the propeller afterwards but cannot. The reason for this is that Krobak has stolen it for his master who needs the propeller to knock down the Gem of Destiny. Nils is disheartened. Fortunately, the Black Elf does not know how to use the propeller and asks Krobak to bring Nils to that he can teach him. He slyly promises to return the propeller to Nils. Nils learns that if the Black Elf knocks down the gem, the future will be terrible for all his friends in the forest. Thanks to Lina, Nils manages to escape, taking his propeller with him.
