Kristoff is a Swedish troll who is from Sweden. He is one of Derek and Scott's best friends, next to Roderick.
He is a bluish green troll. He wears a red vest. He is somewhat like Cooper from Dreamworks' Trolls. He is very fun loving.
Kristoff is a very relaxed troll who enjoys having fun. He's always bubbling with excitement. When he's sad, he whistles his favorite tune "Du Gamla, Du Fria" which is Sweden's National Anthem. His favorite dance moves are The Troll Jump and Jive and The Lindy Hop.
