The featured yellow jungle animal's name Hugo was dropped from the title, since there at the time was a popular TV troll with that name. Another yellow jungle animal with a long tail, the marsupalimi, came first, but at that time, it only made the jungle uncertain in comics. Line animation is expensive and it took years after Valhalla before Danish animators pulled together making this film, where music by Flemming Quist Møller helped the popularity among younger kids along. Teaming up with a female fox Hugo having left his home manages to make it in the civilized yet chaotic concrete jungle. Jesper Klein lent his voice to one of the characters, and that actor made as number of voices to other animated films adding to his varied career in the media. However, you can actually tell that this feature thought out in Danish has a number of details in the rendering showing that this is not just a foreign film with voice dubbing. The success continued with a sequel maintaining the level of quality from the first film.
