Angelica graduates from the ""Mind My Manners Charm School"", where she is taught good manners. She puts her knowledge of manners to work when an important guest, an executive for Charlotte's company, is invited to Drew & Charlotte's for dinner, leading to Angelica teaching the Rugrats some manners.

Rugrats play ""Follow The Leader"", with Dil being the leader. When Dil sucks his thumb (mimicking Stu when he sucks his own thumb after hitting his hammer on it), the Rugrats do the same, but fail to stop. When the adults noticed this, they panicked after reading in a Lipschitz book that thumb-sucking leads to poor academic skills and bucked teeth. Angelica uses this advice to get Chuckie to believe that they'll turn into ducks, when they get ""duck

A the Java Lava, Angelica brings over her new "Hip Teen Cynthia" doll, which talks. However, when Angelica wasn't looking, the Rugrats have broken the doll. Shortly after Stu took it home to fix it, Cindy, a high school intern, came over to work at the Java Lava. When they noticed that Cindy looks and talks like Cynthia, Angelica and the Rugrats thought that Cynthia came to life. Meanwhile, Cindy causes trouble for the Java Lava by not working at all -- she considers nail polish, magazines, and phone conversations to be more important than actually working.

Didi wanted Stu to clean up the living room for Boris & Minka's visit, which includes putting the toys away. Sarcastically, Stu says that he would put the toys, and the babies, into the crawlspace. Angelica interprets this by banishing the Rugrats to the crawl space, where they could play there, while Angelica has the living room all to herself, to the displeasure of Susie. Meanwhile, Stu invents an automatic plan
