The Bullwinkle Show
Rocky & Bullwinkle - Upsidaisium (17) - The Missing Mountain or Peek-a-Boo Peak (2x81)
: 19, 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.
