- Arc Fatigue: The entire "Upsidaisium" story arc is only 36 segments long in 18 episodes. And if you think that's bad enough, you should know that the very first story arc of the show, "Jet Fuel Formula", is only 40 segments long, all in an arc spanning 20 episodes.
- Big-Lipped Alligator Moment: The odd "Flowers" bumper inbetween the cartoons. There's no context to it at all.
- Ensemble Dark Horse: Bullwinkle himself; considering that the series was originally called The Rocky Show, Rocky was usually given top billing, but as the series progressed Bullwinkle tended to get more spotlight time of the two.
- Lampshaded in "The Box-Top Bad Man" arc when the World Economic Council recruited Bullwinkle, who has the world's biggest collection of box-tops, to help them uncover who is counterfeiting box-tops.
- Genius Bonus: The show was famously absolutely loaded to the brim with political satire and historical references no kid would get, which played a big role in keeping it popular for so long.
- As Leonard Maltin pointed out in "Of Moose and Men", Peabody's Improbably History is practically an early, completely accidental, example of an Edutainment Show. Peabody and Sherman's encounters with historical figures often had quite a lot of information about said figures.
- Hilarious in Hindsight:
- Also, one of the parts of "Metal-Munching Mice" is "Fright Flight, or A Rocky to the Moon".
- At one point in "Box Top Robbery", Bullwinkle is pictured in a pose that resembles dabbing.
- Inferred Holocaust: Rocky and Bullwinkle duck under a hail of machine gun fire from the Mud City Manglers, but the Narrator says the audience in the end zone weren't so lucky.
- Memetic Mutation: "Moose and squirrel" has now been attributed to Russia's meddling in the 2016 presidential elections.
- Moe: Rocky. Is. Adorable. And yes, this does include badass points as well.
- Name's the Same: Very few times an episode title will be reused. "A Snitch In Time," "The Yegg And I," "The Inside Story" and "Visit to A Small Panic" are among them.
- Nightmare Fuel: Gidney and Cloyd's first appearance in the pilot episode was a bit spooky, with the two fading in and out Cheshire Cat-style with creepy early '60s "spacey" sound effects. The limited animation actually made the scene eerier.
- Boris looked pretty menacing in his first few appearances.
- The Metal-Munching Moon Mice.
- Also in the Pottsylvania Creeper story is the Pottsylvania Creeper, a plant that eats everything in sight, including people. Then its vines form a rocket that explodes in the air, which produces more Pottsylvania Creeper seeds. At the end of the story, we never again see the people it ate. Since Boris, Natasha and Fearless Leader also get eaten at the end, this should be Fridge Logic since they show up alive and well in future stories.
- The Problem with Licensed Games: Rocky and Bullwinkle got three unique games on the NES, SNES, and Gameboy respectively, and all three were unplayable disasters.
- Tear Jerker: After June Foray died someone made this fanart of Rocky meeting up with Bullwinkle in the afterlife.
- Values Dissonance: There was some racial stereotyping in the Peabody and Sherman sequences involving Chinese and Native Americans that wouldn't be allowed today. Fortunately, the recent movie avoided this completely.
- Viewer Gender Confusion: June Foray's voice for Rocky is an all-time classic performance, but it sounds distinctively female despite the cartoon's insistence that Rocky is male.
YMMV / Rocky and Bullwinkle
