S01E120: Rocky & Bullwinkle - Box Top Robbery (8) - Fall Story or Adrift in the Lift

Surprisingly, Bullwinkle does not fall down the shaft but instead finds himself standing atop a mountainous pile of counterfeit box tops that fills the shaft from the basement nearly to the top floor. As he begins to sink into the box tops, Boris and Natasha are busy shoveling their ill-gotten gains into a huge truck in the building’s basement. Rocky and Bullwinkle attempt to get to the bottom of things, but when they innocently step into a down elevator, they are shot high into the sky by an exploding bomb planted by Boris! Meanwhile, Boris and Natasha make their escape.
