To play with this Harley Quinn doll, you can pose her in different positions using her flexible joints. Hold her mallet in her hand to create action scenes. When you're done playing, keep her in a dry place away from direct sunlight to prevent color fading. Make sure to handle her gently to avoid any damage to her pigtails or outfit. If she gets dirty, you can use a soft, damp cloth to wipe her clean. Remember, this doll is for kids aged 3 and up, so adult supervision might be needed for younger kids.
