Plot

Eleven-year-old boy genius Jimmy Neutron lives in Retroville with his parents, Judy and Hugh, and his robot dog, Goddard. Jimmy's friends are overweight Carl Wheezer and hyperactive Sheen Estevez, and his long-standing rival, intelligent classmate Cindy Vortex, teases him for his small stature. After Jimmy launches a communications satellite into space, hoping to contact alien life, he crashes his makeshift rocket into his house's roof, upsetting his mother. The next day, Jimmy, Carl and Sheen learn of the grand opening of Retroland, an amusement park. Popular kid Nick Dean convinces the boys to sneak out and attend. Jimmy's mother refuses to let him attend the park that night. After his jetpack accidentally starts a fire in the house, she grounds him. Taking Nick's advice, Jimmy uses his shrink ray invention to sneak out and meets Carl and Sheen at Retroland for a night of fun.
