This interactive book will guide you thematically through eight different environments on our planet, such as forest, savannah, desert, sea, and more. On each page, you will learn what animals live in each respective environment, what their names are, what sounds they make, and what makes them interesting. You can then test your knowledge with fun quizzes, which are always divided into three categories: find an animal by its name, find an animal by the sound that it makes and find an animal by some interesting fact that you have just learnt. Contents: over 900 sounds and texts on 16 interactive pages. IMPORTANT NOTICE This book only works with the Tolki interactive talking pen. The Tolki pen is not included in the package! You can buy it separately here. For the interactive talking pen to work properly, it is necessary to download the corresponding audio files, which are available free of charge at this site. The audio files must be first downloaded into your PC and then copied into the pen’s memory. Therefore, a computer is needed to complete the operation.
