experiment. Because Johnny has Susan, Mary, and Dukey by his side, he can live any kid's dream, only to find that most dreams never turn out as hoped. Johnny is very hyperactive and often messes with his sisters' inventions, causing trouble and mayhem, but just as often proves himself to be clever, such as frequently tricking his sisters or saving the day from whatever danger happens to show up. He is also stubborn, and like many kids, he doesn't like school; if anything, he will often go to great lengths to avoid any work, often using his sisters' inventions to do so, resulting in himself and others in trouble. One of Johnny's main nemeses is Eugene "Bling-Bling Boy" Hamilton, a fellow arch-rival of the Test sisters and frienemy of Johnny and Dukey, yet also has an unrequited crush on Susan. Another is Sissy Cutler, a tomboy who often serves as Johnny's rival/friend; the two may have crushes on each other, but both frequently deny and compete against each other. Missy, Sissy's pink labradoodle, is Dukey's rival/crush. A third is Bumper Randalls, the school bully who constantly picks on Johnny. Meanwhile, the General from the army base Area 51.1 and Mr. Black and Mr. White, two federal agents from the Super Secret Government Agency (SSGA), are shown to be close friends with the kids and often get them out of trouble or recruit them for an assignment, help them, distract, or annoy the Tests on various occasions.
