This cartoon is part of Lesson 15. Professor Balthazar (Croatian: Profesor Baltazar) is a Croatian animated television series for children about an old inventor that was produced between 1967 and 1978. It was created by animator Zlatko Grgić. The series revolves around benevolent genius Professor Balthazar. In each episode, someone in his surroundings has a problem, which he duly considers and invariably finds a solution to. He then activates a magical machine and produces an invention that will solve the problem. The characters of the series do not speak in any intelligible language, and the plot of the episodes is instead recounted by a narrator in voice-over.
