"ArMOOgeddon", written by co-creators Waco O'Guin and Roger Black, takes place in the distant future. We join Steve Williams, the only Brickleberry park ranger who managed to escape death at the hands of the Alien Cow Invasion. Future Steve was captured, but escaped and has joined forces with a small group of human rebels in an underground hidden base. Future Steve must travel back in time to the year 2015 and kill head ranger Woody Johnson, whose actions led to the Invasion and the destruction of all humanity.
