Representatives for Red Skelton contacted the producers claiming that Bullwinkle's voice was an unauthorized use of a character voice created and owned by Skelton for his character "Clem Kadiddlehopper". Jay Ward responded by having a segment on the show where Bullwinkle would address the issue . . . in a voice that was a deliberate imitation of Clem Kadiddlehopper.

Given the inherent absurdity of this cartoon, in which practically anything goes, and nothing is impossible, it could be argued that all of the show's continuity errors are deliberate gags, rather than goofs. They are kept on the list because they are interesting.

Daws Butler (voice of Aesop's son, and numerous incidental characters) has his credit removed after the first season. This was due to a contractual stipulation with Hanna-Barbera, which stated that he could not receive on-screen credit for work at another studio.

The commonly available episodes of "Rocky and His Friends"/"The Bullwinkle Show", as released on DVD between 2003 and 2011, differ from the original broadcast versions in several ways. "Rocky and His Friends", originally broadcast on ABC for two seasons (1959-1961), and its later incarnation "The Bullwinkle Show", originally broadcast on NBC for three seasons (1961-1964), are combined under the blanket title "The Adventures of Rocky and Bullwinkle and Friends". The combined five seasons are presented on DVD with altered title sequences. The opening and closing animation originally from Season 2 of "Rocky and His Friends" has been applied to most of the episodes from each of the first two seasons, with a newer title logo and appropriately re-dubbed voice-over for the show's rebranding as part of "The Adventures of Rocky and Bullwinkle and Friends". Furthermore, due to copyright issues, the original Frank Comstock theme music from "Rocky and His Friends" has been replaced by the music composed by Fred Steiner for "The Bullwinkle Show". The DVD releases also use the altered-for-syndication versions of the opening and closing sequences that excise any mention of the show's original sponsor, General Mills. The original opening animation from "The Bullwinkle Show" is not used for any episode in any season, as the episodes originally broadcast as "The Bullwinkle Show" (represented as Seasons 3-5 of "The Adventures of Rocky and Bullwinkle and Friends") use animation from earlier seasons of "Rocky and His Friends" (including the Season 1 animation that was replaced on the Season 1 DVDs). While the DVDs present Rocky & Bullwinkle's serialized adventures in their chronological order, there's some debate over which backup segments ("Fractured Fairy Tales", "Peabody's Improbable History", "Aesop and Son", "Dudley Do-Right of the Mounties", "Bullwinkle's Corner", "Mr. Know-It-All") should be paired with each episode, as the segments have been mixed and matched, separated and recombined countless times in the decades since their original broadcast. While the current DVD versions of these episodes are considered the "official" versions in circulation, they fall short of being accurate representations of the show as originally broadcast from 1959-1964.
