“Let’s have a singing contest," Espen shouted from the troll's hand. "If you win, we'll cook ourselves to the most delicious meal you've ever tasted. If I win, you'll just have to eat us raw." The troll rubbed his beard for a long while. He tried to figure out why these little creatures would go into such a bet, but thinking made him hungry. “OK. That sounds like a fair deal.” The troll sang. His voice echoed between the walls, deep, grave and loud. The cave started shaking. Cracks appeared in the walls. Big rocks fell from the roof, down on the troll's head.
