Now, years later, these satellites have begun sending their first videos back to Earth...and the stars of the show are two goofy robots. In this story, Joe and Rob find themselves face to face with the magical Dragon Bots who have invaded their planet. Can they convince the Dragon Bots to become friends, or will the Dragon Bots fry their circuits?
