The teacher is surprised by the appearance of the children, but immediately agrees to teach the two.
The troll children, called Petra and Peter, are very popular among their classmates.
Kino.de describes Peter och Petra as an imaginative Astrid Lindgren film adaptation, about the friendship of the boy Gunnar with two troll children.
[3] Reinhard Kleber of the Kinder- und Jugendfilm Korrespondenz thinks that the film adaptation promotes "friendship and tolerance", without "being too pedagogical".
Kleber commented that director Agneta Elers-Jarleman succeeded in presenting these values in such a way that even very young audiences are able to understand them.
