The set comes with an illustrated book that is half storybook and half instruction manual. Nikki and Barbie (sold as a separate set. Only the dolls are different.) The set works through problems in biology, chemistry, physics, engineering, art, and design.
When Barbie was fired, Nikki phoned her to talk about it. Barbie didn't understand how Nikki could have found out if she hadn't personally told her, but Nikki told Barbie it was all over the gossip websites online. Barbie thanked Nikki for telling her, even though the news left Barbie upset and demotivated.
