The enchanting picture book classic by Otfried Preussler, suitable for children aged 4 and up. Miller Michel and his mill boys from the Grundelmühle are preparing a delicious dinner. Suddenly, the water sprite appears from the mill pond. "Can I have some too?" asks the grass-green creature with the wide frog mouth. Miller Michel chases the unwelcome guest away, but the sprite quickly seeks revenge: night after night, he causes such a ruckus that no one wants to stay in the mill anymore. However, a wandering bear leader and his bear still want to spend the night there. Will that turn out well?.
