This film is nostalgia for me even though it was made all the way back in 1954. Karius og Baktus (Karius och Baktus, Karius and Bactus e t c) is a Norwegian film by Ivo Caprino made with the pedagogical purpose of getting kids to brush their teeth properly. It features two irritating "tooth trolls" nesting in some kids teeth.
In the 70s they made us watch it in school several times and I know I thought it was kind of grim. Of course we preferred watching it to having regular classes. As if the film wasn't enough I was given the book, probably by my Norwegian godparents. Was it because I had bad personal hygiene? I would like to think not.

By the way, if you like stop motion movies and you happen to stumble upon a movie called Flåklypa Grand Prix (Pinchcliffe Grand Prix) you should watch it. This is Ivo Caprino's masterpiece from 1975; also great nostalgia for me.
