How to use: First, take out the alligator heads and tails. Look at the color - coded marks. Try to match the uppercase letter on one part with the corresponding lowercase letter on another part. You can also play a memory game by hiding some parts and then finding the matching ones. Attention: Keep the alligator pieces away from small children who might put them in their mouths. Don't let the pieces get wet as it might damage the markings. Maintenance: Wipe the alligator pieces with a dry cloth regularly to keep them clean. If there's a bit of dirt, you can use a mild soap and water, but make sure to dry them thoroughly afterwards.
