In the small town of Pottsville, boredom comes easily to mischievous twins Jasmin and Jesse Thomas. One dull Friday night the twins decide to camp out in their backyard, and sneak out to the bogs over by Potts Field to find out whether they can hear any bog monsters. While searching for bog monsters, the twins become hopelessly lost. Suddenly they hear a loud bang, followed by a bright ball of light flying just above the treetops and making a loud whistling sound. Jasmin and Jesse watch as a strange aircraft crashes into the woods. While searching for survivors of the crash, the twins encounter an alien visitor, who incessantly repeats everything they say. Once the twins recover from their shock at encountering Orfin Kojumbobababul, or Orfin Bob, as they call him, the adventures begin. From a near-deadly fall in a cave, to blasting through asteroid fields in a spaceship, and fending off an attack by the evil Haywardians, the action doesn't stop for a moment. Orfin Bob and the Thomas Twins is a thrill ride right up to the very last page.
