Trollz

Fenn the Troll hates the Troll pastime of pranking, and is teased so much for it that he runs away. But when a long-suffering park ranger starts capturing the other Trolls, it's up to Fenn to rescue his family and friends.
Trolls have a fun time pulling pranks on unsuspecting humans near a campsite, and they compete to see who can pull off the best prank.
