Lumpik Spuntik

On the Danish island of Bornholm, trolls live deep underground according to strict rules - the most important of which forbids venturing to the surface, because humans are dangerous. Curious Spuntik is meant to become the master of a cave one day, but instead he plays pranks and rides on the backs of bats.

When a strange rumbling echoes from the surface, he secretly sets out to discover what is happening. Unexpectedly, his little sister follows him - and their expedition soon turns into an adventure in the human world, full of danger and magic.
