No! No! No! The little troll is terribly angry. It’s like there’s a storm inside him, with lightning shooting out of the sky and thunder rumbling loudly. Yes, that’s exactly how he feels: like a rumbling and grumbling troll. A grumbletroll! Eventually his friends get fed up with his yelling and go off to play without him. Will the little troll be able to make up for his bad behavior  and win back the favor of his friends? Grumbletroll serves as a model to help children recognize and learn ways to stop fits of rage that we all struggle with when things don't go our way.
