This is how it sounds on the farmSix sounds make the most popular farm animals "come alive". Listen to the rooster crow! What does the cow do? Who is bleating? This book is a sensual visit to the farm, the only thing missing is the smell of the barn. This sound book is one of the most popular books in the series and has already sold more than 350,000 copies. Typical sound book: Each book contains 6 easily triggered sounds with a total playing time of approx.100 seconds. Pressing the colour-coded dots on each double page activates and deactivates the sounds. Children from the age of 2 can easily operate the books on their own; for younger children, parents should press the sound buttons, as the fine motor skills and strength of little fingers are not yet sufficient. All titles in the series are subject to strict safety requirements and quality controls. Each sound button is tested for functionality before delivery. The volume of the sounds complies with the European Toy Safety Directive. The books are supplied with 3 standard LR 1130 button cell batteries of 1.5 V each. The batteries can be easily replaced. This is the case, for example, when the sounds no longer have the full playing time or can only be triggered with difficulty.
