* Tooter Shellby in ''WesternAnimation/TheSnorks'' can't speak, but only toot out of his snorkel. The other Snorks can't understand him, but some other sealife can.
* All adults in the various ''ComicStrip/{{Peanuts}}'' animated specials. (They are also [[HeWhoMustNotBeSeen unseen]].) They all sound like a muted trombone. This is because they were voiced by a trombonist who was told to mimic the line's delivery with the instrument.
* ''WesternAnimation/SouthPark''
** Kenny's mouth is (almost) always covered by his parka, so his speech comes through as muted nonsense. Matt Stone is actually saying lines through his hand, and knowing the context can usually allow you to recognize many of the words. This allows the creators to get through some words that would otherwise be censored. Some of his speech is readable in closed captions. Other times his dialogue consists of verbal gibberish used for comic effect, as a sort of "fill in the blanks" device. Because we rarely hear Kenny's unmuffled voice, the identity of [[spoiler:Mysterion]] is not spoiled early just by hearing his voice, due to the fact that he takes a gruff intonation that clashes with the clean [[spoiler:farewell in TheMovie]].
** Timmy can only say his own name and a series of meaningless grunts. This was originally supposed to represent his mental disability. However, in later episodes he occasionally shows understanding of complex situations, and attempts to communicate complicated messages through inflection and gestures.
** In one episode they have [[Series/JerseyShore a strange creature from New Jersey called "Snookie"]], which can only speak in weird gibberish and say "Snookie want smoosh-smoosh."
* Coco in ''WesternAnimation/FostersHomeForImaginaryFriends''. Frequently, the other characters repeat her lines a la RepeatingSoTheAudienceCanHear: "Coco coco!" "Ripoff artist?!?" The ambigious nature of her dialogue is often played for laughs, such as when Coco makes a suggestion about dealing with a common enemy that leaves everyone else shaken and Mac replying "[[NoodleIncident I think we'd go to jail if we did that]]." Her clucking does, however, match the syllables of an equivalant, sensible phrase in English ("Co-CO!"/"Yeah, right!").
* Snowpea in ''WesternAnimation/MuchaLucha'' who is only capable of saying [[AmbiguousGender his or her]] [[PokemonSpeak own name]].
* Man, talkin' bout dang ol' Boomhauer on ''WesternAnimation/KingOfTheHill''. Boomhauer's speech actually is decipherable, but his MotorMouth pacing, array of {{verbal tic}}s, and thick {{a|mericanAccents}}ccent often make it possible only to get the gist of what he's saying. The show often subverts the gag in a variety of ways for comedy:
** Sometimes he momentarily becomes ''completely'' incomprehensible (except for his usual {{verbal tic}}s), and for the character he's talking to to act like he just said something profound.
** Another gag is for minor characters to not understand him at all, even when he is being relatively clear.
** And yet another is for his friends to tell him they can't understand a word he's saying, due to echo, bad phone reception, etc.
** One episode featured the four main characters each telling [[TheRashomon their side of the same story]]. In Boomhauer's version, he is completely intelligible for the first time, and the other characters all talk with his usual speech patterns.
** His mother and younger brother share his unique speech patterns.
** Lampshaded in an early episode where Hank makes friends with Willie Nelson; at Nelson's party, we see Boomhauer talking to BobDylan, who's just as hard to understand.
* Japanese exchange student Toshi on ''WesternAnimation/AmericanDad''. He has accurate subtitles, but his friends always react as if he said something else entirely.
* In a similar manner, Papi on ''WesternAnimation/TheProudFamily'' speaks only in Spanish, with accurate subtitles about how much he hates Suga Mama.
* Bluey from WesternAnimation/AvengerPenguins
* Mush-Mouth on ''WesternAnimation/FatAlbertAndTheCosbyKids''. Though his speech was simply normal speech with a "buh" added after every vowel, and was thus entirely intelligible i-buf you-buh pai-bud a-butte-buntio-bun.
* Parodied on ''WesternAnimation/DrawnTogether'', in which Ling-Ling (a send-up of Pikachu from ''Pokemon'') speaks in badly garbled pseudo-Japanese, called Oriental in one episode; the other characters have to read his subtitles to understand him, when they can at all.
* Gibber, one of the air pirates from ''WesternAnimation/TaleSpin'', would only whisper into the ear of the person he wished to talk to. The audience never heard exactly what he said, only the other's reaction to it.
* Likewise, in the Clyde Crashcup shorts on ''WesternAnimation/TheAlvinShow'', Crashcup's assistant Leonardo would only communicate by whispering into Clyde's ear.
** He did speak audibly on one occasion, when upset with Clyde, in a sort of whimpering wail, without any real words to it.
* Simon on ''WesternAnimation/FriskyDingo'', who speaks only in quiet mumbles which the characters in the show can apparently understand but which are incomprehensible to the viewer. On careful examination, it appears that the voice actor simply repeats the same nonsense sentence fragments, such as "When I was seven..." over and over.
* When Ben from ''WesternAnimation/{{Ben 10}}'' is in his beastly Wildmutt form, he qualifies. There's nobody who can understand him, though.
** Also from ''Ben 10'', the alien bounty hunter Sixsix, who appears in the episodes "Hunted" and "Galactic Enforcers" and the made-for-tv movie ''Secret of the Omnitrix'', speaks an unknown alien language. Those working with him tend to be able to understand him, and it's implied that he's pretty mouthy. Apparently you can avoid RepeatingSoTheAudienceCanHear if no one wants to repeat it.
* Lil' Cheney on ''WesternAnimation/LilBush'', he begins all his sentences with rah, rah, rah followed by a random word relating the conversation.
* Parodied in ''Disney/LiloAndStitch''. Stitch will occasionally revert to an alien language, often for the purpose of [[PardonMyKlingon saying something rude]]. Later in the film, he manages to convince Jumba to help him rescue Lilo from Gantu [[TranslationYes with a single syllable]].
-->'''Jumba''': After all you put me through, you expect me to help you just like that? ''Just like that?!''\\
'''Stitch''': Ih.\\
'''Jumba''': Fine.\\
'''Pleakley''': "Fine?" You're doing what he says?\\
'''Jumba''': He is very persuasive.
** And then, of course, the joke gets even funnier when [[LiloAndStitchTheSeries the show]] implies that "Ih" [[BluntYes just means "yes."]]
* Shnitzel in ''WesternAnimation/{{Chowder}}'' can only say "Radda," but everyone can understand him as if he's saying full sentences.
** This was {{lampshade|Hanging}}d in one episode, where Schnitzel reads a card to a board game... that ''actually reads'' "Radda Radda Radda."
*** Another episode implies that he has quite a mouth on him, as it shows he had a swear jar ''filled to the brim''.
**** In another episode, he actually becomes so relaxed that he starts speaking normally for a few seconds.
*** Schnitzel: "Radda radda." Chowder: [[SugarWiki/FunnyMoments "What do you mean you're still dead inside?"]]
* Pretty much every robot in ''WesternAnimation/WallE'' either talks in beeps and whirrs or can only say its name plus a couple of extra words. The irony is it surpasses some other cartoons by doing that alone.
** The bots gain some tonal expressiveness as the movie goes on. EVE, in particular, starts off sounding very robotic and by the middle of the movie has a recognizably human (if distorted) voice.
* Wasabi on ''WesternAnimation/SushiPack'' speaks only "mustard", but the other members of the Pack can understand him just fine. Ben, not so much.
* On ''[[Franchise/CareBears Care Bears: Adventures in Care-a-lot]],'' the robot Wingnut speaks in beeps, whirrs, and clicks, but all the Care Bears are able to understand him. Oddly, his creator, Grizzle, is unable to understand him. In one episode, Wingnut translated for another robot that only spoke in blurps.
* H.E.L.P.E.R., the RobotBuddy of ''WesternAnimation/TheVentureBrothers'', speaks in a series of frantic beeps, which doesn't seem to impair any of the characters in the show from understanding what he says.
** On a couple of occasions H.E.L.P.E.R. has behaved as if everyone has ''completely'' misunderstood what he was trying to convey, although, considering the audience, they may have simply ignored his advice and done something stupid anyway.
* ''WesternAnimation/TheClangers'' only ever spoke in slide whistle tones, which nevertheless had the rhythms of human speech. This was probably because they did in fact have "lines" (though they were never heard by the audience) and when BBC read that one of them was "Bugger it! The bloody thing's stuck!" they were not amused. Their friends, the Soup Dragon and the Iron Chicken, only spoke in growls and squawks respectively. All of these non-verbal communications were interpreted by TheNarrator as necessary.
* The title character in ''IvorTheEngine'' could only communicate through his organ-pipe whistle. How comprehensible he was varied from episode to episode and character to character, though Jones the Steam seemed able to hold full conversations with him.
* Zipper on ''WesternAnimation/ChipNDaleRescueRangers'' rarely speaks anything the viewer can understand due to his often fast and very high-pitched voice (the high pitch being appropriate for him being a fly). The other Rescue Rangers all seem to be able to understand him to some degree, although Monterey Jack is really the only one who seems to be able to understand him perfectly.
** WesternAnimation/ChipAndDale themselves were The Unintelligible in most of their shorts with DonaldDuck.
*** Donald Duck ''himself'' is difficult (but possible) to understand most of the time, and goes full-on unintelligible when angered enough. One short had him completely unintelligible all the time until he swallowed special pills (which temporarily gave him a normal human voice.)
** If one were to slow down their dialogue, they speak very clearly; it's worth noting that until 1950, all of their dialogue was repeated from their first episode "Private Pluto".
* The eponymous character of the Canadian cartoon ''KevinSpencer'' apparently does speak, and the other characters around him react as if he had actually said something, but the audience never hears his voice. Instead, the show's voice-over narrator tells us what Kevin "says."
* The ''WesternAnimation/LooneyTunes''' Tasmanian Devil, with several notable exceptions ("What for you bury me in the cold, cold ground?"). In the spinoff series ''Taz-mania'', his family seems to understand his growls and gibbers just fine.
** There's also Buster/Shorty from the short "Rabbit's Kin", his high pitched sped up voice makes it difficult to understand what he is trying to say, however, if you were to play it in slowmotion you can understand him perfectly.
** Lola Bunny in ''WesternAnimation/TheLooneyTunesShow'' when she's talking really fast.
* The Godpigeon in the "Goodfeathers" shorts on ''WesternAnimation/{{Animaniacs}}'' spoke in such an impossible mumble (an extreme [[NoCelebritiesWereHarmed parody]] of MarlonBrando as [[Film/TheGodfather Don Corleone]]) that he had to be translated by his associates. The one time he was subtitled, the pigeon he was talking to completely misunderstood him. (He thought he was being given romantic advice; the Godpigeon really just wanted to go get pasta.)
* There was also an episode of ''WesternAnimation/PinkyAndTheBrain'' where there were two old fellows, one of which understood the other's incoherent rambling.
-->*mumble mumble*
-->"Yes, yes, I know, I know, but where on earth are we going to find a duck and a hose at ''this'' hour?"
* The World Leader in ''WesternAnimation/TheSecretShow'' speaks in an unintelligible gargle that only her husband can understand -- he translates for both the viewers and the other characters.
* Recurring character, Monsieur Meccaneux the mechanic in WesternAnimation/VictorAndHugo has a great line in rambling Yorkshire-ese which is often met with mute imcomprehension by the brothers.
* All dogs in ''WesternAnimation/TheMightyB'' are The Unintelligible. This wouldn't normally be worth noting, except for the fact that they're the kind that the other characters can understand fine, just not the audience.
* Gary, Spongebob's pet snail from ''WesternAnimation/SpongebobSquarepants'', can only communicate through meows, but everyone understands him just fine.
** Except at one point where his response to one of Spongebob's borderline [[{{Cloudcuckoolander}} insane]] ideas is, "Ehh, NO."
-->Spongebob: Oh what do you know? You're a snail!
** And when Spongebob was able to visit Gary's dream, revealing the snail's true [[SesquipedalianLoquaciousness loquacious nature]].
* Bucky the squirrel from ''Disney/TheEmperorsNewGroove'', although if Kronk is around, he SpeaksFluentAnimal.
* Grubber of the Gangreen Gang in ''WesternAnimation/ThePowerpuffGirls'', who communicates purely in raspberries. Despite this, he can still imitate people's voices flawlessly and once demonstrated that if he stands up straight he speaks clearly (and generally looks less weird).
* Klunk and the General, in ''DastardlyAndMuttleyInTheirFlyingMachines''.
** In reality, if one listens to the General carefully, they can tell he is actually just talking very fast.
* Rufflefeather from the "Go Go Gophers" segments of ''WesternAnimation/{{Underdog}}'' speaks a fictitious American Indian language. It doesn't offer much variety to the phonemes; in fact, if Runningboard didn't understand him, we might assume that he just sputters insanely. This is ironic, because Rufflefeather is TheSmartGuy who comes up with most of their plans to screw up the cavalry.
* Ron Stoppable's pet molerat Rufus in ''WesternAnimation/KimPossible''.
* Fiskerton of ''WesternAnimation/TheSecretSaturdays'' speaks in a series of grunts and mumbles. [[WordOfGod According to the series creator]], his voice actor has a script of what he would say in English, but translates it to 'Fisk-speak'. Fisk does have bits of easily intelligible speech mixed in with the gibberish (most notably, his {{catchphrase}}, "Say what?"), though.
* One of the members of Lars' clique in ''RocketPower'', though Lars seemed to be able to understand him perfectly.
** Sam even once referred to him as [[WesternAnimation/FatAlbertAndTheCosbyKids "Mush Mouth"]]
* The (very un-P.C.) animated adaptation of ''[[WesternAnimation/TheDickTracyShow Dick Tracy]]'' from 1961 had, of course, Mumbles. His partner in crime, Stooge Villa, was the only character (or at least, only other gangster) that could understand him.
* One episode of ''WesternAnimation/TheSimpsons'' had Homer telling Marge something in a panic.
-->'''Homer''': Marge! (unintelligible nonsense spoken rapidly)
-->'''Marge''': Homer, slow down!
-->'''Homer''': (unintelligible nonsense spoken slowly)
-->'''Marge''': ''Think'' before you say each word!
* On his second apperance on ''WesternAnimation/TheFairlyOddparents'', [[NoCelebritiesWereHarmed Sylvester Calzone's]] speech is so slurred it's impossible for the viewer to understand him.
* In ''WesternAnimation/YellowSubmarine'', Old Fred tries to get the Beatles to help him, but his agitation has his entreaty to each of them coming out in frantic, unintelligible gibberish, always ending in "...BLUE MEANIEEEES!!!" (which, by the time they get to George, Ringo and John have joined in).
* James William Bottomtooth III, James William Bottomtooth VI and Virgil Mastercard from ''WesternAnimation/FamilyGuy''.
** Peter's brewery co-worker, Opie, speaks in complete gibberish that the audience can't understand, but everyone else can understand him perfectly.
* Rico from ''WesternAnimation/ThePenguinsOfMadagascar'' to an extent. Although as the series progresses, his vocabulary increases to occasionally include intelligible phrases and words besides "Ka-boom!"
* TheVoice over the telephone example: The General in ''WesternAnimation/DastardlyAndMuttleyInTheirFlyingMachines''.
* Clockwork Smurf and Wild Smurf of ''TheSmurfs'' are both this in the cartoon show, whereas in the comic books they either are able to speak in Smurf language from the start or learn how to do so.
* Paw Rugg from ''The Hillbilly Bears'' on ''WesternAnimation/TheAtomAntShow''; he mumbles most of his sentences where the only intelligible word is usually the last one.
* Vulturo of ''WesternAnimation/HarveyBirdmanAttorneyAtLaw'' has this as a VerbalTic where he descends into incomprehensible mumbling every sentence.
* The Adults in ''WesternAnimation/EdEddNEddy'', any time we hear them "speaking", it is usually garbled mumbling or sound effects.
* The villains of the pilot episode of ''WesternAnimation/TheTick'', the Idea Men, could not be understood because the helmets they wore muffled their voices too much. They had to wave a sign with their ransom demands in front of a camera in order to get The City to understand what they wanted.
* In ''WesternAnimation/TransformersPrime,'' Bumblebee does not speak, presumably for similar reasons as his movie counterpart. He communicates by way of electronic beeps a la R2-D2, and is understood just fine by his fellow Cybertronians, but can't use human speech. Raf Esquivel can understand him anyway, and as of the end of season one, the reason for this remains unknown. Even he has said he doesn't know why he can understand 'Bee.
** This gets plot relevance later on when [[spoiler:It exposes the fake Optimus Prime, who can't understand a word he's saying.Not that it helped much.]]
* Without a [[TranslatorMicrobes Universal Translator Mustache]], the alien Meap from the ''WesternAnimation/PhineasAndFerb'' episode "The Chronicles of Meap" can only say the word "meap", which is utterly meaningless to English speakers. To be fair, though, it's evidently a legitimate language amongst his species, where the single word contains ''implausibly'' high amounts of context and nuance. To illustrate, in "Meapless in Seattle", Meap has to warn his home planet that [[spoiler:the villain, Mitch, had obtained the source of Cutonium and was returning with it to their home planet with the intent to take it over, and as such to ready the armies for war]]. Trying to explain the situation in English to another fellow alien only gets a confused "meap?" in response; taking off the translator mustache and uttering a single "meap", however, gets ''all of that'' across instantly.
** In "Tri-Stone Area", the entire ''cast'' is turned into this, since the episode revolves around caveman versions of the main characters who spend the episode speaking in a nigh-incomprehensible caveman language (with the only english coming from the photo-animation cutways that feature the animators explaining what's going on).
* Epoch from ''WesternAnimation/BuzzLightyearOfStarCommand'', his associates understand his screeching and gibbering just fine.
* [[MotorMouth Pinkie Pie]] become this in the ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' episode "Bridle Gossip" when her tongue swells up after walking through the poison joke. When the main cast goes to confront Zecora, thinking she caused the various problems they're suffering with a curse, and Pinkie wants to sing her song about Zecora again, she briefly tries, before begging Fluttershy to do so. Fluttershy agrees, not sounding thrilled about the idea.
* Used to sneak a muffled PrecisionFStrike [[GettingCrapPastTheRadar past censors]] in ''BURN-E'', one of the ''WesternAnimation/PixarShorts'' that came alongside ''WesternAnimation/WallE'', who does not speak actual words as OTTO and WALL•E or EVE do, merely electronic "sounds" that resemble words.
* In ''WesternAnimation/TomAndJerry: Shiver Me Whiskers'', the red and blue pirates speak in variations of "Argh" while their parrots translate for them. However, the purple pirate speaks normally and it's his parrot who speaks in "Argh".
* Bluey from ''WesternAnimation/AvengerPenguins'' spoke in some nearly incomprehensible language.
* On ''WesternAnimation/{{Futurama}}'', Nixon's clone of Spiro Agnew could only speak in grunts due to his lack of a head.
* The former title character of ''WesternAnimation/WheelieAndTheChopperBunch'' cannot talk like the other characters, instead only communicating by honking and displaying symbols across his windshield.
