Help, I Shrunk My Friends
Hilfe, ich hab meine Freunde geschrumpft

Melanie (14) is a new pupil at the Otto Leonhard High School, and Felix takes a real shine to this newbie, who’s upbeat and feisty, albeit sometimes seeming a little naive – much to the annoyance of Ella and Felix’s gang. They believe that Melanie is responsible for a number of small thefts that have been happening at the school since she arrived.
Events take a drastic turn when the class goes on a school trip with head teacher Schmitti, Felix’s Dad as a replacement teacher and all the museum objects belonging to the benevolent school ghost Otto Leonhard. They travel to the little place where the ghost was born to set up an exhibition there. To protect his magic objects Otto Leonhard has taught Felix the secret art of shrinking. When Felix’s friends almost mess up his date with Melanie, he shrinks them spontaneously to a tenth of their size. Just for a short time, he thinks to himself. But once Melanie has left, the magic ball has also disappeared and the indignant miniature-sized friends have to spend the night in a cardboard box under Felix’s bed. Is Melanie behind the thefts after all? Does her upfront, chipper facade conceal a bigger secret? In the process of restoring his friends to their proper size Felix not only has to shrink himself, he also has to confess his love to Melanie and admit his mistakes to his friends. They have to find the real reason for this mysteriously botched class trip and confront their vindictive opponent: the former head teacher Hulda Stingbeard, who has risen from the dead and is determined to banish the good school ghost Otto Leonhard from the school building once and for all.
