On a family camping trip, Ben found the Omnitrix in a forest. Although his grandfather said not to mess with it, he did anyway, and actually figured out some hidden features, which he used to get the Omnitrix back after it was taken by the Plumber, and then Vilgax. At the end of the episode, he and the Plumber teamed up to find Azmuth, the creator of the Omnitrix, and get some real answers.
