 The aim of the series was to stimulate the imagination of the audience and to teach social interaction.In the first five episodes the two dolls "Maxifant" and "Minifant played" in the series, which then got their own series, because the production partners separated.Instead, the puppets "Biff" and "Wuff" (designed by Jan Gulbransson) and the animated character "Wummi" were used.
