Der frechste Troll der Welt (Krølle Bølle)

Billy the troll lives safely underground with his family and doesn’t care much for rules. That’s why he casually ignores the number one troll rule: Never go to the surface, because humans are dangerous. Together with his sister Bonny, he explores the human world and makes a shocking discovery: Humans are planning to build an amusement park that would cause the trolls’ cave home to collapse. But trolls aren’t so easily defeated, so they’ll do whatever it takes to protect their home.
