Rocky & Bullwinkle - Upsidaisium (34) - The Spell Binders or Hex Marks the Spot (2x155)

Air date: Jan 15, 1961

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.
