-->''"It walks... like a '''''man!'''''"''
-->--''WesternAnimation/OpenSeason''

This trope is about the fact that some of the animals on the same end of the SlidingScaleOfAnthropomorphism 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 SlidingScaleOfAnthropomorphism.

It's not always a case that the two-legged characters are more intelligent or more "humanized" than the others, but the TropeNamer, ''Literature/AnimalFarm'', and the trope's name suggest this case.

They are "humanized" more so that they're drawn with a [[CivilizedAnimal realistic]], [[FunnyAnimal semi-realistic, or simplified anatomy]], as opposed to the [[PettingZooPeople humanoid bodies, hands, and]] [[HumanlikeFootAnatomy even feet]] like what some Creator/{{Disney}} characters and a few WesternAnimation/LooneyTunes, [[WesternAnimation/TinyToonAdventures Tiny Toons]], and WesternAnimation/{{Animaniacs}} characters have.

Examples that are NearlyNormalAnimal, TalkingAnimal, PartiallyCivilizedAnimal, and CivilizedAnimal 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 FunnyAnimal examples are allowed. No [[PettingZooPeople Humanoid Animals]] or any animal that is supposed to move around on two legs, like birds.

Subtrope of FunnyAnimalAnatomy.

Sometimes, however, a single character, most often a CivilizedAnimal or a FunnyAnimal, [[AnthropomorphicZigZag can shift between]] [[RunningOnAllFours using two legs and four]].

!!Examples:

[[foldercontrol]]

[[folder:Anime and Manga]]
* In ''Manga/AnimalLand'', some animals walk on two legs and some walk on all fours. A number of them though [[AnthropomorphicZigZag zigzag]] between walking on two and four.
* Meowth from the ''Anime/{{Pokemon}}'' 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, Meowths 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 Meowths 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.
[[/folder]]

[[folder: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 [[AudienceSurrogate human-like]] (to the point where he is hardly ever seen not walking upright these days). By comparison his pal [[DogsAreDumb 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.
** And in an early strip we actually see the first time he walks on two legs "on-camera" rather than this being a background thing, with Charlie Brown trying to teach him to stand on two legs and Snoopy immediately getting the hang of walking on them.
* ''TheFarSide'' had quadrupeds walking upright as often as it had them on all fours.
** The ''{{Barnyard}}'' example may have been InspiredBy a FarSide 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''.
[[/folder]]

[[folder:Film]]
* Alex the lion, Gloria the hippo, and Maurice, King Julien, and Mort the lemurs from ''WesternAnimation/{{Madagascar}}'' usually stand on two legs, but Marty the zebra and Melman the giraffe would sometimes stand that way too.
* Boog the Bear from ''WesternAnimation/OpenSeason'' 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 ''Disney/ThePrincessAndTheFrog'' usually stand on two legs. Louis apparently does it to play the trumpet properly.
* Timon is the only character in ''Disney/TheLionKing'' that walks on two legs (not counting Zazu, who, being a bird, is exempt from this trope).
** The other meerkats in ''Disney/TheLionKing 1 1/2'' usually walk on two legs as well.
*** TruthInTelevision 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 ''Disney/{{Cinderella}}'' stand on two legs.
* The mice in ''Disney/TheRescuers'' usually stand on two legs.
* Timothy Q. Mouse from ''Disney/{{Dumbo}}'' stands on two legs.
* The wild animal characters in ''WesternAnimation/OverTheHedge'' stand on two legs.
* Invoked by Remy in ''WesternAnimation/{{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 ''WesternAnimation/{{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 ''WesternAnimation/IceAge'' movies all walk on two legs.
** Being a ''ground'' sloth, Sid's ability to rise onto his rear legs is justified, albeit only when he's reaching for high branches to feed.
* WesternAnimation/RoverDangerfield often walks on two legs.
* Two-legged Charlie B. Barkin from ''WesternAnimation/AllDogsGoToHeaven'', a German Shepherd/Collie mix, contrasts with Itchy Itchiford, who walks on all fours because of his Dachshund anatomy.
* Inverted in ''Disney/{{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 ''WesternAnimation/{{Rango}}'' is a biped except Rattlesnake Jake since rattlesnakes don't have legs, and the armadillo, who is a quadruped.
* In general, the characters in ''WesternAnimation/KungFuPanda'' (those that fit this trope anyway) walk on two legs, but some switch to all fours when running, presumably just for the sake of speed.
* In ''WesternAnimation/TheSecretOfNIMH'', all the talking animals are bipedal, while the rats used to walk on all fours before escaping from NIMH. During the tractor scene, Mrs. Brisby alternates between the two.

[[folder:Literature]]
* ''Literature/AnimalFarm'': The TropeNamer. 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.
* Retconned in the ''{{Spellsinger}}'' novels: in the first one, Jon-tom is informed that most hoofed mammals aren't intelligent, but later books show these quadrupedal warmlanders talking and using tools designed to be grasped with lips.
* Walter Brooks' Freddy the Pig started out on four legs but in later books stood on two legs when necessary, such as when he pretended to be a midget during a certain detective case.

[[folder:Video Games]]
* Most of the time, Franchise/DonkeyKong walks on all fours except when he carries something like a barrel. In ''VideoGame/DonkeyKong64'', however, he always walks on two legs, yet still has the typical posture of a gorilla when he's just standing.
* In both ''VideoGame/SuperMarioGalaxy'' and ''VideoGame/SuperMarioGalaxy2'', all of the Koopas in the game (which are now normally supposed to be bipeds) are actually reverted back into quadrupeds, while both [[BigBad Bowser]] and [[OverlordJr Bowser Jr.]] are still bipeds.
* In both ''VideoGame/JetSetRadio'' games, Potts the Dog stands on all fours...until you unlock him as a playable character.
* ''VideoGame/FinalFantasyVII'' plays with this with a sequence on the Junon Cargo Ship in which Red XIII is in disguise as a human and has trouble standing on two legs. The theme for the Cargo Ship, which has a somewhat comic feel, is translated variously as "It's Hard to Stand on Both Feet!" or "It's Difficult to Stand on Both Feet, Isn't It?"

[[folder:Western Animation]]
* In the Disney adaptation of ''Literature/TheWindInTheWillows'', 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 WesternAnimation/ClassicDisneyShorts 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 ''WesternAnimation/ChipNDaleRescueRangers'' likewise usually stand on two legs.

** Snowball the hamster and most of the mice from ''WesternAnimation/PinkyAndTheBrain'' 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 ''WesternAnimation/FamilyGuy'' usually walk on two legs.
* Same with Tim and Arianna the bears from ''WesternAnimation/TheClevelandShow''.
* Baloo the bear walks on two legs both in ''Disney/TheJungleBook'' and ''WesternAnimation/TaleSpin'', but Shere Khan only assumes a two-legged stance in ''WesternAnimation/TaleSpin''.

* Both Ratty and Mole from ''WesternAnimation/MrBogus'' walk on two legs.
* In ''WesternAnimation/TheSimpsons'' Bart once got an elephant, and the family was concerned all the time with it. The cat and the dog try to do anything to call the Simpsons' attention... including to stand in two legs and say that they love them. They fell to the ground one second afterwards.

[[folder: RealLife]]
* [[EverythingsBetterWithDinosaurs Dinosaurs.]] They're the first bipedal vertebrates known in history.
** At least, the theropods are.
* This is generally best done by plantigrade mammals, such as apes, baboons, capuchin monkeys, giant pangolins, bears, and the extinct ground sloths, while digitigrades like dogs, rabbits, and cats are generally a little less capable of this and unguligrade animals like horses and cows even less capable of this.
** Most mammals that are bipedal, like kangaroos, wallabies, jumping mice, kangaroo rats, jerboas, and springhares, hop bipedally rather than walk that way, and sifakas and indris stand and leap on two legs.
* Cockroaches [[http://newscenter.berkeley.edu/2012/06/06/stealth-behavior-allows-cockroaches-to-seemingly-vanish/ run on their hind legs]].
