The Bullwinkle Show

Rocky & Bullwinkle - Upsidaisium (23) - Bullwinkle at the Bottom or A Mish-Mash Moose (2x106)

Air date: Dec 10, 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.
