Musti is a multi-colored outdoor and indoor world of trees, flowers, houses and familiar household objects. This world stimulates the imagination of little children. The Mustis are the model family and Musti himself is never really naughty or bad, just mischievous or unthinking, like all children. Musti also has lots of friends who enhance the world of Musti with a flair and personality all their own. The drawings, figures and storylines radiate a childish simplicity.
