In page Ivo Caprino:

"

In the mid-1940s, Caprino helped his mother design puppets for a puppet theatre, which inspired him to try making a film using his mother's designs. Ivo used the surplus puppets as inspiration for his first animated film, Tim and Tøffe (1948), the result of their collaboration. The eight minute film, however, was not released until 1949. Several other films followed, including two 15-minute shorts that are still shown regularly in Norway, Veslefrikk med Fela (Little Freddy and his Fiddle), based on a Norwegian folk tale; and Karius og Baktus, a story by Thorbjørn Egner of two little trolls—representing caries and bacterium—living in a boy's teeth. Gude made the puppets for these films as well.[citation needed]
