As we traipse down the yellow brick road, while hearing the tinkling sounds of the whistling melody, we are welcomed back into the cheery world of Eureka. The air is clear, the mood upbeat and everyone is bustling busily with activity. All is right in Eureka — except one thing: Carter has been fired as town sheriff. Not one to sit in despair, Carter quickly lands another promising job with the Department of Homeland Security and we meet Sheriff Andy, the robot-drone sent to replace him. Sheriff Andy is quite literally a sheriff-in-a-box and quickly ends up a butt of jokes with such noms de jure as Robo-Cop and Tin-Man.
