A book that brings the zoo into the children's room. Here, the animals come to life: Simply press the large sound buttons and the lion roars, the penguins waddle, and the elephants trumpet. What do meerkats sound like? A book featuring five real animal sounds in unique sound quality and pleasant volume. The favorite zoo animals of little ones can be heard: lions, penguins, elephants, meerkats, and chimpanzees. A continuous story provides an interactive reading experience. Fun for both young and old. Pressing the sound buttons activates the noises, making it very easy for children. Since toddlers can trigger the animal sounds themselves, the book remains exciting for a long time and is great for self-entertainment. The books come with two standard AAA batteries (with a voltage of 1.5 V). These batteries are easy to replace when the sounds can no longer be activated. The practical on/off switch ensures that the batteries are preserved.
