After accidentally throwing the baseball into the window of a house next door, Brad Carbunkle sends his brother, Tuck to retrieve the ball, but he meets a robot girl named XJ-9 (she calls herself "Jenny") who gives him the baseball, scaring the pants off of him. Then, he tells his brother there's a robot inside, but he doesn't believe him. Jenny belongs to a scientist named Dr. Nora Wakeman, who wants her to save the world, but she meets Brad, sneaks out, and then hangs out, but Tuck is still afraid of her.
