"An enchanting fantasy about the life of a young water sprite growing up in the cool green world of the mill pond. Endowed with a daring spirit, this lively little sprite ventures into many exciting and amusing episodes, including a trip with a strong current over the mill wheel, a joke played on a naive fisherman which saves Cyprian the Carp, a punishment for contracting dry feet, and a host of additional pranks, games and adventures calculated to delight and entertain." –
Kirkus Reviews "Elements of folklore in Preussler's books are intertwined with conversations, funny dialogue, discussions of old and young, and angry disputes that are rooted in the everyday life of families and school. Preussler revealed...that he possessed an almost inexhaustible fantasy, an unfailing sense of humor and situation comedy. German children between the ages of four and twelve are still his fans." –Horst Kunneman,
Bookbird "Mr. Preussler's books were read aloud to generations of German children. They adored his characters." –Douglas Martin,
