Little Tikes DiscoverSounds Tool Box Perfect for children 6-36 months, the Little Tikes DiscoverSounds Tool Box is a great way to introduce your little one to everyday shapes, colors, and numbers. They will love placing each shape in its designated area and bopping them through with the hammer. Lights and sounds are activated as each shape passes through. Then, when all shapes have gone through, simply flip the play area over and begin again. A terrific sensory development toy, the DiscoverSounds Tool Box promotes hand/eye coordination, spatial recognition, and will keep your baby entertained for hours.
