Jay Ward and partner Alex Anderson originally created Rocky as part of The Frostbite Falls Review, a proposed pilot that wasn't developed.

Other episodes presented Rocky's flight abilities as similar to those of Superman (hovering in mid-air, ascending in altitude, carrying objects, etc.

Occasionally, Rocky would rely on Bullwinkle's strength (via an acrobatic maneuver) to provide him with an extra boost in flight speed, as shown in his attempt to reach the hovering Mount Flatten in the second season's "Upsidaisium" storyline.

According to the series, Rocky learned his aerial skills at the Cedar Yorpantz Flying School (a play on the idiomatic expression "seat of your pants").

In the final version, I must have drawn and erased that miserable little rodent fifty times, and he ultimately ended up looking like Rocky the Flying Hamster.

During a broadcast of an Atlanta Braves baseball game in the late 1990s, a real squirrel scampered onto the field and caused a delay in play.
