Using the Fisher - Price Purple Monkey Musical Storybook is super easy. To start the fun, press the sun button, and you'll hear the Purple Monkey song and see the lights come on. You can also open the book and turn the pages to enjoy more music and sounds. When your baby wants to take it on the go, they can hold the easy - to - grasp handle. As for maintenance, keep it away from water and rough play. If it gets dirty, use a soft, dry cloth to clean it. Make sure to use the recommended batteries and replace them when the music gets weak. Always supervise your baby while they're using the storybook, especially if they're under 12 months old.
