Zipi and Zape are the sons of Don Pantuflo, an eminent fancier and philatelic, and Doña Jaimita, his long-suffering mother, always complaining that her children "don't eat him." Zipi and Zape have one of the main objectives of their antics at school, since there they get together with their friends (and not so friends): Invi, Wanda, Puag, Peloto or Evilina ... They all give poor Don Minervo , the teacher, more upset than he.
