In Real Life, moose, Alces alces, are at least moderately intelligent as far as animals go, and there's nothing to say they aren't at least as smart as other deer species. In fiction, however, they can be shown as very dumb. At best, they are a bit slow on the uptake, and at worst, they can even be portrayed as Too Dumb to Live. They very often speak with a Simpleton Voice.
Likely due to the inherently funny name, moose are the only species of deer portrayed as stupid in fiction rather than graceful or marvelous, including themselves under the older name "(Eurasian) elk" (not to be confused with Cervus canadensis, the large deer species referred to as "elk" in North America). And no, there's absolutely no difference. "Moose" is just the Abenaki name, which caught on in the East around the same time the Lewis and Clark expedition found the similar-looking Northwestern "elk". They are also the largest extant species of deer which, paired with their enormous antlers, often translates into "big and clumsy". More negative portrayals of moose will have them be The Brute with Dumb Muscle tendencies, like Angry, Angry Hippos.
- Two guys in a truck stop suddenly when a moose stands in their way and asks if they got their brakes at Pep Boys. When they nervously answer "Yes," the moose says "I appreciate it" and leaves.
- Played with in Kemono Friends: Moose is more Hot-Blooded than stupid, but she always uses the same strategy of charging directly at the battle without ever thinking how. Truth in Television, as normal moose will exactly do that in Real Life with its antlers.
- While not a moose, the Dumb Muscle from Archie Comics is named Moose, so he may qualify symbolically.
- Completly averted in the swedish comic Hälge... Well, with the exception of Rubbade Runar (rough translation: disturbed/deranged/unhinged/crazy Runar). The others wonder how he managed to survive every moose hunt so far. One strip has him walk up to a group of hunters and politely ask them to stop shooting Hälge, not even understanding why they're shooting. The hunters quickly decide that he's not worth shooting since "he must have some kind of disease".
- Downplayed with the title protagonist of Super Agent Jon Le Bon* ; while Jon understands basic concepts and his responsibilities at the Agency, he's got a childlike mindset and isn't quite all there. It's attributed to the fact that the other agents were too busy to raise him frequently after he was left on their doorstep.
- Rutt and Tuke, the moose brothers from Brother Bear. They managed to crash a mammoth in a mountain, if their idiocy means anything.
- The sequel to Bambi, Bambi 2, had an old grouchy porcupine insult Bambi's father, the Great Prince of the Forest, by calling him a "big moose".
- The Morris and Borris books, starring Morris the Moose, a scrawny-looking moose who for some reason has the tail of a unicorn
- Moostache, which is about a moose who is very clumsy because his extremely huge mustache constantly gets in his way. He eventually ends up falling in love with a female moose with an extremely large hairdo.
- If You Give a Moose a Muffin, a sort-of sequel to If You Give a Mouse a Cookie. In the animated series, he doesn't really see all that dumb, but still has the typical stupid-sounding voice associated with a dumb moose.
- Completely averted in the Norwegian children's book Dyrene i Hakkebakkeskogen ("In The Forest of Huckybucky"), where the moose is the most solemn and dignified of the animals. He doesn't have much of a role in the story, but when he speaks, the other animals listen.
- Similarly averted in the Swedish franchise Svingelskogen ("Festuca Forest"), which has quite a lot in common with Hakkebakkeskogen. Again, the moose isn't a major character in the stories, but he's very much respected and looked up to. In fact, here he seems to be the closest thing the animals in the forest have to a leader/ruler. He doesn't get involved a whole lot, but when he gives orders nobody ever argues.
- In fact, since the moose is the largest wild animal in both Norway and Sweden, and the antlers remind people of a crown, in those two countries the moose is often called "King of the Forest." Consequently, any moose who shows up in Norwegian or Swedish fiction is likely to be portrayed as regal and stoic, or at least aspiring to be — though the Norwegian ones might sound a little silly because they're imitating the speech patterns of King Harald V of Norway. The idea of moose being idiots as a whole, though, is pretty alien to Norwegians and Swedes.
- Thidwick the Big-Hearted Moose. Though Thidwick isn't so much of an idiot as he is a total pushover.
- In the online version of Diary of a Wimpy Kid, Greg writes a report on moose. His only true fact is one he recalls from reading a book called Dumb Animals.
- Semi-subverted with Mr. Moose on Captain Kangaroo. Not the brightest puppet a hand could control, but he could still trick the Captain to say something that will have ping pong balls raining down on him.
- The campfire song "There Was A Moose" or "The Moose Song" concerns a moose who has some trouble drinking juice.
- The moose in Capcom's Breakshot has a goofy, Bullwinkle-esque voice that certainly sounds the part.
- Bullwinkle J. Moose from The Adventures of Rocky and Bullwinkle and Friends, of course.
- Averted with the Highmountain Tauren in World of Warcraft, who are every bit as intelligent as their cousins on the great plains.
- Lumpy from Happy Tree Friends is the absolute epitome of this trope, and provides the current page image. He frequently does stupid things that endanger the lives of the other cast members (often even himself), and tends to do very incompetent things. As a matter of fact, he's Lethally Stupid to the point that he's killed more characters than Flippy (who has an Ax-Crazy Superpowered Evil Side), some cases including Flippy himself.
- In Strawberry Death Cake, Winston is very eccentric and has a quirky personality, often coming off as a simpleton, or at least absent minded, but at other times displays a vast knowledge of the supernatural. A possible explanation lies in the fact that he is a weremoose and was originally a full human. The full details of his curse have yet to be revealed.
- Bullwinkle J. Moose of Rocky and Bullwinkle is the Trope Codifier, if not the Ur-Example.
- In Camp Lazlo, Scoutmaster Lumpus is a moose. He is an extremely incompetent, apathetic Jerkass Woobie who doesn't even like being a scoutmaster. As a Running Gag, he has trouble identifying Clam's species (a pygmy rhino). On the other hand, as a nature lover, he is useful to the scouts because he fights the system to keep the camp open.
- The Mickey Mouse short Moose Hunters. "Kiss me!" Averted in the short Morris the Midget Moose, however.
- Inverted in the short-lived animated series Frootie Tooties, by Honeycombe Animations, where Strawberry Moose is explicitly described as the most intelligent of all the animals and has a rather large vocabulary.
- Averted realistically in The Wild Thornberrys where Eliza had to prevent a bull moose from attacking her sister Debbie and their friend Shane when it mistook them for another male moose while they were playing with a discarded moose antler. The moose is portrayed as simply territorial with bad eyesight (as Real Life will attest). It even offers to help Eliza rescue Debbie and Shane from a cave-in after she, in a moment of Sanity Slippage scares off another encroaching bull moose by waving and screaming at it.
- Franklin had the titular turtle working together with a new student who, despite being the same age as Franklin and his classmates, easily towered over them. Initially frightened of his appearance, Franklin befriends the new student and learns of his creativity as an artist despite his awkwardness. Of course he's a moose named Moose.
- Despite only looking like a moose, Yakkity Yak is a Too Dumb to Live yak for fits in this trope.
- Averted with Moose in the animated adaption of Little Bear. For the few times he's shown, he's helpful and quite intelligent. Of course, this may also play to part that he's a Reasonable Authority Figure looking out for young animals.
- Averted with Noggin's former mascot, Moose A. Moose. He never showed any signs of being incompetent during the bumpers featuring him.
- The moose in the Heckle and Jeckle cartoon "Moose On The Loose" is pretty bright, getting the best of the two at the cartoon's end.
- The Cartoon Network original short "Ignoramooses" stars two dense moose who give a hunter a hard time after convincing themselves they're his new pets.
- Downplayed on Mack & Moxy, with Mack, the blue moose partner of Moxy, a pink raccoon. He's smart enough to take a lead role in the adventures on the show and be generally helpful. That said, official descriptions for the program also describe him as having "two left feet" as well as being a "lummox" and he's also something of a Literal-Minded Big Eater. He also speaks with the slow, Simpleton Voice typical of the characterization.
- Averted with Tyrone of The Backyardigans, at least when you compare him to his red oni, Pablo. Of course, none of the Backyardigans are completely stupid anyway, even if they don't make the smartest moves while they're playing pretend.
- Yin Yang Yo!: Ultimoose, the first villain faced by Yin and Yang, is Testosterone Poisoning incarnate, but not much else. This is actually more of a conscious choice for him, as he considers books and smarts to be too girly for his tastes.
- It's apparently not unusual in autumn in Scandinavia for elk to become inebriated by eating fermenting apples. In 2011 a Swedish moose made international headlines after getting drunk and stuck in a tree.
- Moose eat plants that grow in streams, some of which contain a parasite that attacks the brains of the moose. Infected moose are mostly aggressive and unpredictable, though, not stupid per se.
- A full-grown bull moose weighs over half a metric tonne, and they very frequently run across highways in the rural forested regions of the northerly countries where moose are common. This produces very-often-fatal results for the moose and often-fatal results for the occupants of the vehicles that collide with them (to say nothing of the condition of the vehicle itself), because a moose is so tall that when its legs are knocked out of the way, the rest of the moose just skips over the hood and crushes the people inside. Of course, the moose — like the drivers that run into them — are just trying to go somewhere. Just as the driver might not expect a sudden obstacle when rounding a bend, the moose doesn't expect an object to appear out of nowhere coming toward them at dazzling speed. Paired with the prominent notices of animal crossing, it is more often human complacency than the animals' fault — especially if the driver is driving over the speed limit around blind corners at dusk or dawn when the moose are most active. Road engineering mitigates this with cleared road shoulders, gigantic fences, and/or special underpasses for the moose to walk through, although these are obviously expensive and installed only on major roadways and freeways.
