Four Legs Good, Two Legs Better

""It walks... like a man!""

- Open Season

This trope is about the fact that some of the animals on the same end of the Sliding Scale of Anthropomorphism are more likely to stand upright and others are more likely to stay on all fours. In other words, it is about one animal on two legs and an animal on four legs being close to each other on Sliding Scale of Anthropomorphism.

It's not always a case that the two-legged characters are more intelligent or more "humanized" than the others, but the Trope Namer, Animal Farm, and the trope's name suggest this case.

They are "humanized" more so that they're drawn with a realistic, semi-realistic, or simplified anatomy, as opposed to the humanoid bodies, hands, and even feet like what some Disney characters and a few Looney Tunes, Tiny Toons, and Animaniacs characters have.

Examples that are Nearly-Normal Animal, Talking Animal, Partially-Civilized Animal, and Civilized Animal versions of animals that are supposed to stand an all four legs but are depicted as standing on two legs at least some of the time are ideal, but Funny Animal examples are allowed. No Humanoid Animals or any animal that is supposed to move around on two legs, like birds.

Subtrope of Funny Animal Anatomy.

Sometimes, however, a single character, most often a Civilized Animal or a Funny Animal, can shift between using two legs and four.

Anime and Manga

 * Meowth from the Pokémon anime learned to walk on two legs so that he could be respected by humans. In an ironic twist, this made him a freak amongst other Meowth.
 * Oddly though, Meowth's have always been shown to be on two legs in their game sprites (albeit in stances like an actual cat or dog trying to walk or sit on their hind feet) and Meowth's in future episodes are shown to walk on two feet. In the Gold and Silver remakes, Meowth's sprites depict them walking on four legs suggesting they aren't the best at two feet walking.
 * Also, the evolutions of some Pokémon that are quadrupeds assume two-legged stances when they evolve (and vice versa). Some are justified, such as Slowbro (as the Shellder that clamp onto their tails provide leverage to weigh them back). Generally, Pokémon that can assume a bipedal stance have better movepools then their quadrupedal cousins.

Comics

 * Very visible in the Garfield comics: the protagonist originally was drawn walking on all four, then switched to walking like a human as he came to be depicted increasingly human-like (to the point where he is hardly ever seen not walking upright these days). By comparison his pal Odie the dog still rarely ever assumes a two-legged stance.
 * Snoopy from the Peanuts comics, movies, and TV specials usually stands on two legs, except for the earliest comics.
 * Jim Davis of Garfield fame admits it was Charles Schulz who taught him how to design both four- and two-legged posture for an animal character.
 * Oddly in an early comic, he understands he loves Sally because she's the only human who knows how to walk on four legs.
 * The Far Side had quadrupeds walking upright as often as it had them on all fours.
 * The Barnyard example may have been Inspired By a Far Side comic where cows were standing up until a spotter shouted "CAR!" Then they went down to four legs when a car went by, after which they went back to standing.
 * Heathcliff was shown on two legs quite a few times. So were Belvedere and the pig in another Jim Davis strip, U.S. Acres.

Film

 * Alex the lion, Gloria the hippo, and Maurice, King Julien, and Mort the lemurs from Madagascar usually stand on two legs, but Marty the zebra and Melman the giraffe would sometimes stand that way too.
 * Boog the Bear from Open Season usually stands on two legs. Elliot the mule deer also stands occasionally, which causes the hunter Shaw (who's already not all there to begin with) to utter the page quote in horror.
 * Tiana and Naveen as frogs and Louis the alligator from The Princess and the Frog usually stand on two legs. Also, Louis the alligator, in order to play the trumpet properly.
 * Timon is the only character in The Lion King that walks on two legs (not counting Zazu, who, being a bird, is exempt from this trope).
 * The other meerkats in The Lion King 1 1/2 usually walk on two legs as well.
 * Truth in Television in that meerkats actually do stand like this in real life to scout their territory, but also Exaggerated because they never walk like that, only stand.
 * The mice in Cinderella stand on two legs.
 * The mice in The Rescuers usually stand on two legs.
 * Timothy Q. Mouse from Dumbo stands on two legs.
 * The wild animal characters in Over the Hedge stand on two legs.
 * Partially subverted in Ratatouille. While the other rats go on all fours, Remy chooses to walk on his hind legs to keep his forepaws clean for eating and cooking.
 * The computer animated movie Barnyard by Steve Oedekerk has the cows standing with four legs, but only in front of humans. They prefer standing on their hindlegs like humans.
 * Sid the sloth, Fast Eddie the armadillo, Buck the weasel, the possums Crash and Eddie, and Scrat from the Ice Age movies all walk on two legs.
 * Rover Dangerfield often walks on two legs.
 * Two-legged Charlie B. Barkin from All Dogs Go to Heaven, a German Shepherd/Collie mix, contrasts with Itchy Itchiford, who walks on all fours because of his Dachshund anatomy.
 * Inverted in Tarzan, as the hero of the movie is a human who walks on all fours and generally behaves like a gorilla, owing to how he was raised.
 * Everyone from Rango is a biped except Rattlesnake Jake since rattlesnakes don't have legs, and the armadillo, who is a quadruped.

Literature

 * Animal Farm: The Trope Namer. It's the central concept of the story: as Napoleon (a pig) became more tyrannical and corrupt, he ultimately abandons one of the most important characteristics that the animals took pride in because of how it made them different from the humans - the notion that four legs are good and two legs are bad - and decides to walk on two legs, like a human.

Video Games

 * Most of the time, Donkey Kong walks on all fours except when he carries something like a barrel. In Donkey Kong 64, however, he always walks on two legs, yet still has the typical posture of a gorilla when he's just standing.
 * In both Super Mario Galaxy and Super Mario Galaxy 2, all of the Koopas in the game (which are now normally supposed to be bipeds) are actually reverted back into quadrupeds, while both Bowser and Bowser Jr. are still bipeds.

Western Animation

 * In the Disney adaptation of The Wind in the Willows, Cyril Proudbottom the horse sometimes stood on two legs, but Mr. Toad, Ratty, Mole, Badger, and the weasels always stood on two legs.
 * Chip and Dale and Humphrey the bear from the Classic Disney Shorts stand on two legs.
 * Don't forget the comparison in intelligence between the two-legged Mickey Mouse and the four-legged Pluto, down to the point that Pluto is Mickey's pet.
 * Pluto did very occasionally stand on two legs, but he usually walks on all fours.
 * The rodents (Chip, Dale, Gadget, and Monterey Jack), Fat Cat, and a lot of the other animal characters from Chip 'n Dale Rescue Rangers likewise usually stand on two legs.
 * Tom and the other cats and Jerry and the other mice in Tom and Jerry usually stood on two legs.
 * Most Looney Tunes animal characters (not counting the bird characters) stand on two legs at least part of the time.
 * Most Tiny Toon Adventures and Animaniacs animal characters (not counting the bird characters) stand on two legs at least part of the time as well, including the cats Rita and Furrball.
 * Snowball the hamster and most of the mice from Pinky and The Brain usually stand and move around on two legs.
 * But Buttons and Runt pretty much stay on all fours.
 * When Rita and Runt make a Cameo in the Hip Hippos episode, "Moving Experience," Rita is shown running on two legs and Runt is running on all fours.
 * Brian and Jasper from Family Guy usually walk on two legs.
 * Same with Tim and Arianna the bears from The Cleveland Show.

 * The cats in The Garfield Show usually assume an upright stance but the dogs usually don't.
 * Some Word World animals (not counting the birds) walk on two legs and some walk on all fours.
 * In Adventures from the Book of Virtues, Plato walks on all fours, but Socrates and Aristotle usually stand on two legs.
 * All of the animals in Slacker Cats walk on their back legs but the wild tiger they find doesn't (he also doesn't talk) because he's more in tune with his wild side than they are.
