Zbrklík and Hell's Christmas

Devils Zbrklík and Čertidl Tadeáš are doing hellishly well in hell. Together with the she-devil Treperenda, they form a well-coordinated trio. And when one day they open the gates of hell and a very important letter for Father Christmas gets lost in hell, it causes a stir the likes of which hell has never seen before.
As soon as the little devils and she-devils learn of the lost letter, they too long for a real Christmas. But all the devils have a really tricky problem on their hands. How do you actually celebrate Christmas? And what about presents, when Father Christmas has never come to hell before?
Join Zbrklík and his friends on a proper Christmas adventure that will be a little hellish, a little magical, but also wonderfully mischievous.
