They reside in the fictional town of Porkbelly. Johnny is often used as a test subject for his genius twin sisters' inventions and experiments, which range from gadgets to superpowers. Their experiments often cause problems that he must resolve and he must sometimes fight villains in the process. He occasionally saves the world with his sisters' inventions.
