When crops from all over begin to disappear, Sweet Polly decides to visit the location of the disappearances. She falls into a hole and lands underground. There she is met with King Mange, who explains that he and his men have been stealing the crops to weaken the surface dwellers so that they can conquer the Earth. Polly tells them that Underdog will stop them, to which King Mange replies that their weapon, the Molehole gun will burrow a hole into anyone, including Underdog.
