In each episode of this series, one of the famous classical fairy tales of the Brothers Grimm is told in the magical land of Simsala. The local characters Doc Croc and Yoyo move between the story-teller and the episode cast, which they tend to help or at least inspire. Each episode begins with Doc Croc and Yoyo as toys on a shelf brought to life by a magical book with the Brothers Grimm in the hardcover.
