Using this doll is super easy. To transform Ariel from human to mermaid, simply push her shell necklace. You'll see her blue dress open up into a beautiful mermaid tail. To change her back to human form, close the tail and push it up. When playing, keep in mind that the doll can't stand on its own, so you might need to support it. If you want to style her long red hair, you can use normal hair accessories, but be gentle to avoid pulling out the hair. Store the doll in a cool, dry place away from direct sunlight to prevent any color fading or damage to the materials. Also, since colors and decorations may vary, don't be surprised if your doll looks a bit different from others. Each doll is sold separately, so if you want to collect them all, check the availability regularly.
