Mach and Sebestova

Ordinary school children Mach and Šebestová become extraordinary thanks to a donated magic phone receiver. The receiver fulfils their wishes, allows them to visit various places and encounter interesting and unusual situations. During their adventures, the pupils are usually followed by a friendly dog named Jonatán, and they often meet with its owner, Mrs Kadrnožková. Mach and Šebestová attend school and the stories are often associated with the school setting. Two of their classmates, poor students and incorrigible urchins Horáček and Pažout, are the main antagonists of the series.
