How do I make the LOL Surprise Confetti Pop Birthday Sisters doll change colors?

[McTeagan]

To activate the color-changing feature of your LOL Surprise Confetti Pop Birthday Sisters doll, follow these steps: First, use ice water at about 32°F (0°C) for the best results in achieving a cold color change. Be aware that extreme temperatures can sometimes trigger the color change prematurely; if this happens, simply return the doll to its original color by placing it in a room temperature environment, between 68–77 °F (20–25 °C). If the color change is not happening as expected, the doll's temperature might be too similar to the water's temperature. Remember that weather conditions can affect the color change process. Also, avoid storing the doll in direct sunlight for long periods, as this can impact the color-changing capabilities. Note that the color change only works on specific parts of the doll, its fashions, or its accessories, and not all items will change color. Finally, keep in mind that the color change effect on the doll's body has a limited lifespan.
