Hilfe, ich hab meine Freunde geschrumpft
Granz Henman, Germany, 2020o
When new student Melanie shows up at the Otto-Leonhard-Gymnasium, Felix's world turns upside down. Much to the suspicion of Ella and Felix's gang: they believe that Melanie is behind many of the petty thefts that have been happening at the school since her arrival. Things then turn rapidly on the school trip, also because Felix has previously been let in on the secret of shrinking by the school ghost Otto Leonhard.
