This is the best TV show for children ever filmed in Croatia. Filmed in several seasons, it brings mistery, comedy and action in a very entertaining way. Great acting (almost every croatian actor participated over the years), good story and good directing is the only recipe for success.
Quality varies, first few episodes are the best, but the rest is still watchable and interesting. I could mention a lot of not-so-good stuff, but I won't: it would somewhat ruin the impression of the great show I liked in childhood.
