Using the doll is easy. First, make sure the switch on her back is in the Try Me mode. When you're ready to play, move it to the Play mode. Then simply lift her arm, and she'll start singing 'Into the Unknown' with flashing lights on her bodice. Note that the batteries are included, but if they run out, replace them with the appropriate type. Keep the doll away from sharp objects to avoid damage to her clothes and body. When not in use, store her in a cool, dry place. You can remove the skirt and shoes for a costume change, but handle them gently to prevent tearing. Also, be aware that other Frozen toys are sold separately and availability may vary.
