Its Halloween and The Chameleon has stolen the Sythian President's brain and decides to hide out on the most backwater planet he knows: Earth! Sparky and X-5 beam down to Earth to help Betty capture The Chameleon. X-5 is unimpressed with Noah, who is dressed as a robot, and Sparky gets distracted from the mission and gorges himself on Halloween candy. Meanwhile, Betty's classmates get involved in the chase and think its all an elaborate Halloween party!/ The Ranger Girls scout troop, including Betty, is sitting around a campfire one night, telling ghost stories. Betty narrates a "made up" story of Atomic "Betsy" and her crew investigating a deserted spaceship where they experience strange disturbances and noises, including the haunting cries of "Aberdeffia". Atomic Betsy saves the day, with the help of Sparky in a dress!
