The Bullwinkle Show

Rocky & Bullwinkle - Upsidaisium (28) - Supersonic Boom or The Old Mount's A-Moverin' (2x125)

Air date: Dec 24, 1960

Bullwinkle inherits an upsidaisium mine in a mountain that flies because upsidaisium is an anti-gravity metal. The nation needs upsidaisium, so Bullwinkle and Rocky fly the mountain to Washington. Thwarting them at every turn are Mojave Max and Death Valley Dotty.
