This episode starts with Isabelle at the park and shouting at Barbie she went down the slide and Barbie tells her to stop or she might lose her voice. After a few more warnings Isabelle loses her voice. Isabelle is getting upset because Anabelle and her get to sing with Krystal Kayla (Mentioned) tomorrow at preschool. So the next day Anabelle leaves and Ken starts spoiling Isabelle by the following: Eating ice cream, watching a movie, and staying up late. Barbie and Anabelle think it’s unfair. The next day Isabelle gets her voice back. But she was having so much fun being sick that she pretended she was still ill. Anabelle promised Isabelle a video of her singing with Krystal. Isabelle watched it and couldn’t help singing the toon and Barbie came down stairs and caught Isabelle red handed. It’s too late and Isabelle admits everything and says sorry. As in any other episode Anabelle and Tommy pretend to lose their voice too. But failed straight away.
