With the Little People A to Z Learning Zoo, kids can take various trails that lead to fun discoveries. Activate two different modes for two kinds of learning. In one mode, animals make sounds that correspond to open-ended questions posed to your little zookeeper. ABC mode introduces your toddler to the alphabet by asking questions. As little ones head out on the alphabet trail, they can press any letter to hear the beginning letter of that animal's name or the sound it makes.
