Lumpik Spuntik

On the Danish island of Bornholm, trolls live deep underground following strict rules — the most important of which forbids going to the surface, because humans are dangerous. Curious and mischievous Spuntik is meant to become the next master of the cave, but instead he plays pranks and flies on the backs of bats.

When one day a strange rumbling is heard from the surface, Spuntik secretly sets out to find out what is happening. Unexpectedly, his little sister follows him, and their expedition turns into an adventure in the human world, full of danger and magic.
