The Bullwinkle Show

Rocky & Bullwinkle - Upsidaisium (2) - Big Bomb at Frostbite Falls or The Exploding Metropolis (2x5)

Air date: Sep 24, 1960

Possessing more courage than brains, our heroes set off toward Mt. Flatten, the location of Uncle Dewlap's mine. However, bad luck is on the way for them: Boris Badenov, in the guise of a mysterious motorcyclist, switches the road signs. Unfortunately, Rocky and Bullwinkle are unwittingly diverted into a secret military installation--which is filled with landmines! We ask the question: Are our heroes on the Road to Ruin?
