Adventure beckons Lotte, Kalle and Lilli, who set their raft on the
Elbe towards the open sea. Before their plans of discovering sunken treasure are realized, a storm destroys the raft. Pirates rescue them and subsequently demand remuneration. Since the three Sinbadventurers can offer nothing in return, the pirates prepare to throw them back into the sea, but cooler heads prevail: the three children might be helpful in rescuing the pirates' captain, who is being held captive by the man-eater Caesar Knochenschmalz. Caesar Knochenschmalz is not the least bit interested in any deal involving three skinny children, since he has gone to great lengths to fatten Captain Igor. Lotte persuades the man-eater to try some of the tofu which the pirates have on board. Caesar Knochenschmalz is not only enthralled with Lotte's barbecue tofu but also enamored of Lotte herself. He pronounces Lotte to be his bride, and gives Captain Igor back to the pirates. Lotte protests, but Kalle and Lilli convince her to go along with the engagement, as is the only way to save their skin until they can plot their escape. On the way back to Hamburg, the ship runs aground on a seemingly deserted island. The nasty smell of sweaty feet permeates the otherwise enchanted island, whose sole inhabitant is the sorceress, Cindy Magnifiscent. Cindy proceeds to magically transform the uninvited visitors into cows, pigs, sheep and chickens, with the exception of Kalle, who persuades Cindy (holding his nose all the while) to let him wash her feet. Transfixed, she transforms all the animals back into people, saving Caesar Knochenschmalz for last, augmenting his retransformation with a special love-spell. No longer a cow, he falls instantly in love with Cindy and breaks off his engagement to Lotte. Lotte gives Cindy the recipe for barbecue tofu while Cindy and Caesar proclaim their love for one another. The others board the pirate ship and set sail for Hamburg. In between the scenes are two interludes, one comic and one tragic. The first imagines an encounter between
Kaiser Wilhelm II and
Otto von Bismarck, who scheme to get
Heligoland back from the British; the second recounts the catastrophic demise of the 14th century city
Rungholt, explaining how gold might have found its way into the North Sea.
