To use your Barbie Extra doll, you can start by dressing her up in the bold and colorful outfits that match her unique style. Pose her in different ways to create fun scenes. You can also play with her adorable pet. When handling the doll, be gentle as the hair and clothing can get damaged easily. After playing, store the doll in a dry place away from direct sunlight to keep her colors vibrant. Don't try to make the doll stand on her own as she won't be able to stay upright.
