What makes me angry? And how can I get my anger under control? Important questions addressed in a child-friendly way! Pepito lives with his uncle, the great wizard Pepe. The young magician wants to be as famous as his uncle, so he practices his spells diligently every day. Everyone likes Pepito, except when the little magician gets angry. Because then he loses control, breaks things, and is mean to others. His friendship with the little witch Mimi is also put to the test during an outburst of anger. But when Pepito urgently needs help, Mimi is there for him. She also shows him a way to manage his anger. In the end, Pepito even manages to successfully complete a magic show for all the forest inhabitants, even though it didn’t seem likely at times. "Anger is not good for me!" Pepito realizes. Not for any wizard - and certainly not for him.
