The '"Sounds Of The Wild" nature books authored by Maurice Pledger make learning fun for you and your child. The books consist of beautifully illustrated and color accurate pop-up pages showing the animals related to the book title (Jungle, Safari, Ocean, Birds, Night Time, Dinosaurs). There is a micro chip in a (secured by a screw) plastic box on the back cover. This is powered by a replacable button battery (yay! a book that can be used forever; you won't throw it out when the battery dies). Following each set of pop up pages is description and information of the amimals shown on the pop up page. Your child will delight in seeing and hearing the animals. Each set of pop up pages has it's own appropriate sound for the animals depicted. Purchasing "Sounds Of The Wild" books is money well spent; your child is entertained by the sights and sounds and this makes learning an enjoyable experience. This is a book that your child will cherish forever (and maybe pass it down to their children).
