A fairy who moved to Sesame Street during season 37. She's a 3-year-old fairy in training, who attends the Flying Fairy School.(as of Season 40.)

- All Myths Are True: Abby's mom, Maggie Cadabby, is Cinderella's fairy godmother.
- The Apprentice: Hence "Abby's Flying Fairy School."
- Breakout Character: While only appearing in three episodes of Season 37, she became more prominent as the show went on and proved to be a great addition to the cast. She later gained her own solo segments, appears alongside Elmo in nearly all his guest appearances, and even got her own television special.

- Mundane Utility: In addition to transforming one thing into something completely different or conjuring things out of thin air, her wand also makes a handy backscratcher.
- Non-Standard Character Design: She, along with other fairy characters in the show, is one of the few Muppet characters designed with irises.

- Trademark Favorite Food: Very much likes oatmeal.
- Uptight Loves Wild: He clearly loves Ernie because of his free-spirited nature, not despite it and because Bert's life would be boring without him.

- Cassandra Truth: The adults constantly disbelieved Snuffleupagus was real at first. See The Reveal under ''Mr. Snuffleupagus"
- Characterization Marches On: He was initially a fully grown idiot with a hick-like Simpleton Voice to match, rather than the innocent 6-year-old child he eventually became.
- Crying Critters: Despite being a bird, he has cried on several occasions.
- The Cutie: Even in the context of Sesame Street his innocence and sweetness stand out.
- A Dog Named "Dog": A big bird named Big Bird.
- Extreme Doormat: Well, maybe not "extreme", but he has a hard time standing up for himself - he once let Humphrey and Ingrid talk him into giving Radar to Natasha, and he would have lost his nest to Minnie Myna if Chris hadn't helped him.
- Gentle Giant: He's a Big Bird with a good heart.
- Hidden Depths: During the famous episode centered on the death of Mr. Hooper, Big Bird draws various caricatures of the adults - of a quality that you may not normally see from a typical 6-year-old.
- Caroll Spinney is a cartoonist and painter in his down time, overlapping with The Cast Showoff.
- Injured Limb Episode: In one episode, he sprains his wing and needs to have it in a sling.

Big Bird: "Just because."
(Big Bird learns of Mr. Hooper's death)
Big Bird: "Why does it have to be this way?"
Gordon: "Big Bird, it has to be this way because."
Big Bird: "Just because?"
Gordon: "Just because."
- Meaningful Name: Well duh!

- Start My Own: Because Oscar wouldn't let him join the Grouchketeers.
- Trademark Favorite Food: Birdseed, which he eats (or in the case of birdseed milkshakes, drinks) in seemingly infinite variations.
- Vocal Evolution: Big Bird started off as a fully-grown Village Idiot with a deep, hick-like voice. Over time, however, he became a young child of 5 (or 6, depending on when you were watching the show) with a higher-pitched voice. Because the show reuses its old recordings of songs in later episodes, it can be very jarring to hear Big Bird sing the "Alphabet Song" in his "hick" voice in an episode from c.1975 or later.

Peter Linz (2017-present)
An enthusiastic, extroverted prankster who's Bert's roommate and Red to Bert's Blue. He enjoys taking baths with his rubber duckie.
- Baths Are Fun: He loves taking baths, which was established in the very first Sesame Street episode (when he did the "I call my bathtub Rosie" joke), and reiterated with numerous bathtub sketches and songs (including the Breakaway Pop Hit "Rubber Duckie").
- Cloud Cuckoo Lander: Frequently does weird things like talking to a rubber duck or waking up the whole neighborhood with loud off-key opera just so he can know what time it is at night.
- Consulting Mister Puppet: Ernie often talks to his trademark rubber duckie about his problems.
- Couldn't Find a Pen: Bert asks him to make a shopping list, and the only thing Ernie can find to write with is chocolate pudding. Ernie then makes a list of all the writing implements that he couldn't find.

- Crazy-Prepared: In this skit.
- The Gadfly: He loves to prank, trick and tease Bert. Much of his random weird behavior is just done to mess with his friend, because it's funny when Bert gets frustrated.
- Hidden Depths: He lays down an amazing saxophone solo during "Put Down the Duckie."
- He's also a really good painter... even if he does re-imagine Bert as a beatnik.
- I Can't Hear You: "I can't hear you, Bert. I have a banana in my ear."
- Jerk with a Heart of Gold: Well, yeah — you wouldn't think so, but Ernie is a far bigger jerk than Bert. Watching the Bert & Ernie skits, it's sometimes surprising to see just how badly Ernie treats his best friend, often for no good reason at all. He plays tricks on him, makes a fool out of him, steals his snacks or cruelly tempts Bert with snacks before eating them himself, and in general causing him no end of frustration, humiliation and heartache. He also once woke up the whole neighborhood by singing off-key opera just so he could know what time it was at night (and according to one of the shouting neighbors, this isn't the first time he did something like that). When Ernie still comes across as the most likeable and friendly of the two, it's because, well, he is a genuinely sunny and affable person who just wants to have fun and share a laugh with people. He's never malicious, just a little insensitive.
- The Prankster: Usually pranks Bert.
- Pungeon Master: This was an especially pronounced trait of his in the first season.
- A good example would be his very first appearance, when he tells Bert he calls the bathtub "Rosie", and when Bert asks why he replies, "Because every time I take a bath, I leave a ring around Rosie."
- Security Blanket: His rubber ducky.
- Sick Episode: He got sick in the book "Nobody Cares About Me".
- Signature Laugh: "Kshshshshshshshsh!"
- Signature Song: Rubber Ducky, You're the one! You make bathtime lots of fun...
- Something Only They Would Say: The game "Journey to Ernie" runs on this trope.
- Straight Man: Even though he's normally just the opposite, he's sometimes used as this when paired with characters other than Bert, such as Cookie Monster or the Count.
- Vague Age: While he and Bert live alone, he seems naive like a child. His attitude towards naps changes too, sometimes taking them and sometimes not.

- Big Ol' Unibrow: As mentioned under Oscar's entry, it's a species trait.
- Bizarro Universe: Grouch society mirrors human society (right down to similar celebrities — Dan Rather-Not and Donald Grump, for example), but they prefer unhappiness and filth to happiness and cleanliness.
- Blue and Orange Morality: As explained above, they dislike (often downright condemn) nice and pleasant things, and like things that most other people would find unpleasant. Although a bit odd, it sounds simple enough, right? Well, this also means that they like feeling miserable, and yet the nice things they hate make them miserable, which they like and... yeah. Try not to think about it too hard.
- Filthy Fun: Their version of bathing is getting more dirty.
- Grumpy Bear: A species of them.
- Hates Baths: Most grouches hate getting clean.
- My Species Doth Protest Too Much: You occasionally find one that is neat or positive, though never both.

- Frank Oz (1976)

- Bratty Half-Pint: Is just as cranky as her uncle.

- Breakout Character: Introduced as the world's first autistic Muppet, she has become an instant hit with audiences and is in almost as much merchandise as the other characters.

- Character Tic: Flapping her arms in excitement.
- Cloudcuckoolander: Described by Abby as doing things "in a Julia sort of way."
- The Cloud Cuckoolander Was Right: When Julia and some of the other characters go on a shape hunt, Julia repeatedly identifies shapes her team is looking for, apparently incorrectly, only for the rest of her team to discover that the shape is incorporated within the larger shaped object. For example, she says "circle," pointing to a stopsign. Her team points out that it's actually an octagon, only to eventually figure out that Julia is referring to the little circles cut out of the stopsign pole, while everyone else is focusing on the yellow tubes outlining them.
- The Cutie: Try not to go "Awwww" when seeing Julia.
- Girls Love Stuffed Animals: Her toy rabbit is her comfort object.
- Graceful Ladies Like Purple: She is a cute, quirky girly-girl, who's signature outfit includes a violet jumper dress.
- Hollywood Autism: Sesame Street stops in its tracks to point out how atypical Julia is, and she's portrayed as having stereotypical mannerisms.
- Inspirationally Disadvantaged: As storylines progress about Julia, her characteristics are played up. In her first appearance, for instance, she is participating in a game when she begins jumping up and down. Instead of rejecting Julia, the other characters and Muppets decide that jumping up and down is a lot more fun.

- Vocal Dissonance: She's four years old, but she sounds like a grown woman.
Kermit the Frog
- Jim Henson (1955-1990 [the character predates Sesame Street])
Steve Whitmire (1990-2009)note
The Muppet Show's easily flustered host; here Kermit usually plays a roving news reporter in a trench coat. He also often attempts to give lectures to the audience that are inevitably ruined by another character. Jim Henson's definitive role; Kermit and Ernie aren't that different, acoustically speaking. This is especially apparent in Bert and Ernie's Muppet Show guest appearance, where Ernie appears and speaks immediately after Kermit introduces the pair. See also his entry on Characters.The Muppet Show.
- Beware the Nice Ones: Kermit is usually friendly and even-tempered, but when he's pushed too far he can get very angry indeed.

- Call-Back: He makes a surprise appearance in "Elmo's World: Frogs", where he is shown lounging in his apartment.
- Commuting on a Bus: He was a regular in season 1, but concern over his appearances in commercially-oriented non-Sesame medianote led him to get dropped in season 2. But beginning in season 3, Kermit came back in more of a Fake Guest Star role, showing up sometimes for song sequences and sketches (often with Grover and Cookie Monster). Alas, the frog seldom appears these days, due mainly to Disney owning the rights to the character.
- Continuity Nod: While preparing to interview Old MacDonald, Kermit tells one of the farmer's pigs, "You know, you remind me of somebody..." (a reference to The Muppet Show's Miss Piggy).
- "I Am" Song: "Bein' Green" and "This Frog".

- Distaff Counterpart: Created as a female equivalent to Placido Flamingo, likewise being an animal parodying a famous performer.
- No Celebrities Were Harmed: Obviously based on Meryl Streep.
- Non-Specifically Foreign: She has a vaguely Eastern European accent, based on Meryl Streep's role in Sophie's Choice.
- Verbal Tic: "Ja, ja..."
Mrs GrouchOscar's mother, and also the mother of his sister Bunny and brother Ernest.
- Doting Parent: Loves her children in a weird grouchy way.
The Oinker Sisters
- A Lizard Named "Liz": Their last name is "Oinker", which is because they are pigs and pigs say "oink".
- Special Person, Normal Name: One of the Oinker Sisters is named "Suie Oinker".
Oscar the Grouch
- Caroll Spinney (1969-2018)Eric Jacobson (2015-present)
- Adaptational Heroism: Oscar takes up this role in The Adventures of Elmo in Grouchland when he volunteers to go with Telly, Gordon, Big Bird, Maria, and Cookie Monster to venture to Grouchland and get Elmo's stolen blanket back from Huxley.
- Anti-Role Model: One purpose of the character is to poke fun at irritable people. Which isn't to say that his irritation isn't justified sometimes.
- Big Eater
- Big Ol' Unibrow: Huge eyebrows are a species trait.
- Bizarre Taste in Food: He hates foods most would consider nice or healthy, but loves noxious combinations of food that are technically still edible... just really gross. Like sardine ice-cream. Again, it's a species trait.
- Deadpan Snarker: Often shows shades of this trope.
- Early Installment Weirdness: He was orange for a year. (Apparently he still would be, if he ever bathed.)
- Everyone Has Standards: Oscar may be a hoarder of most stuff and hates everything cheery, but Huxley being selfish, ruining his beautiful Grouchland, as well as keeping everything thing he sees (including Elmo's blanket) and never giving them back is where Oscar draws the line.
- Grumpy Bear: He's a Grouch. It's a species trait.
- Hoist by His Own Petard: Every now and then, some of the mean-spirited pranks and schemes he pulls tend to backfire, where he may end up being the victim himself. Often happens when he's frustrated when targeting a rather slow-witted character with his pranks.
- Jerkass: Cranky, rude, and mean. Although as much is allowable on a preschool show. The Muppet Wiki puts it best:Oscar's mission in life is to be as miserable and grouchy as possible, and pass that feeling on to everyone else. When a visitor knocks on his trash can — invariably interrupting him from a nap or an important task — Oscar greets them with a snarl. He complains that he wants to be left alone, although when he's left entirely to himself, he's dissatisfied — there isn't anybody around to irritate or complain to.
- Jerk with a Heart of Gold: The true depths of his jerk nature are often called into question and he can get comically defensive when his reputation as a "true Grouch" is threatened.
- Kick the Dog: Sometimes takes his rudeness a little too far, as when he upset Big Bird by teasing him with How Can Santa Deliver All Those Toys? questions in Christmas Eve on Sesame Street.
- Large Ham: He's as snarky as he is a large ham.
- Nice Job Fixing It, Villain!: There does appear to be an occasional running gag where his intended mean-spirited ways backfire, unwittingly causing pleasant and helpful results for other characters. Much to his dismay, of course.
- The Nicknamer: As far as Oscar is concerned, Bob and Maria are Bright Eyes and Skinny, respectively, and Big Bird is Turkey.
- The Pigpen: Always seen in a trash can, so yeah.
- The Prankster: Sometimes he plays jokes on other characters.
- Sick Episode:
- At the end of one episode, he contracts Grouch Flu from Grundgetta.
- In one episode, he gets "Kind-itis", which makes him kind and rhymey.
- Slave to PR: One has to wonder if he'd be so concerned about being a "real Grouch" - or if he'd be so self-conscious anytime he says, does, or thinks something even remotely pleasant - if it weren't for Grouch society constantly stressing how Grouches are supposed to act.
- Something Itis: In one episode, he gets a disease called "kind-itis".
- Too Important to Walk: He's rarely seen walking. When he needs to be transported somewhere, a garbageman named Bruno carries his can. (He does in Christmas Eve on Sesame Street a few times.)
- Troll: He can definitely come off as this at times, especially when Telly is involved.
- Vitriolic Best Buds: Easily with any of the nice Sesame Street residents that like being sweet and chummy with him, especially Elmo, Telly, and Maria.
- What the Hell, Hero?: He gets this reaction from Leela and Elmo for seeing the Mine-itis outbreak as a cause for celebration.
- With Friends Like These...: Used to be this sort of "friend" to poor Telly.
- Although, they seem to have fallen into a more traditional Type 1 Vitriolic Best Buds as of late.
- Your Approval Fills Me with Shame: Often inverted. As you may expect, he does not appreciate being praised by the other characters for doing something less-than-grouchy.
OvejitaMurray's lamb sidekick, who speaks only in Spanish.—-
- Accessory-Wearing Cartoon Animal: Wears a bow in her wool.
- Amazing Technicolor Wildlife: Is a purple sheep.
- Talking Animal: Is pretty much a normal lamb, but she speaks Spanish.
RalphieBaby Bear's talented parrot.

- Speaks Fluent Animal: Apparently, he speaks fluent Hamster.
Michael Earl Davis (1978 - 1980)
Martin P. Robinson (1980 - present)
A slow-talking, elephantlike creature and Big Bird's best friend. He originally wasn't thought to be real, but was revealed in a Season 17 episode.
- Abandoned Catchphrase: Mr. Snuffleupagus used to always say "Oh, dear" in a worried voice. Big Bird even lampshaded it once; when Snuffy went missing in one episode and BB called the police (an Anything Muppet) to take a report, part of his description was that he said "Oh dear" a lot.
- Characterization Marches On: He started out with a rather odd and perpetually sad personality as well as speaking with a rather creepy, echoing, sad voice. It wasn't until when Marty Robinson took over the character that, though still sad occasionally, his personality became more cheerful and his voice had a wider range of emotions.
- Early Installment Weirdness: Snuffle used to have wide yellow eyes with green sclera and was understandably changed to a different lazy eyed design as the debut appearance was... unsettling, to say the least.
- The Eeyore: Used to be one of his defining character traits, but he steadily grew out of it as time went on.
- In-Series Nickname: "Snuffy." He calls Big Bird "Bird."
- Leitmotif: Has a theme tune sometimes.
- "Metaphor" Is My Middle Name: When he helps rebuild Big Bird's by blow-drying the mud that holds it together with his snuffle, he claims that his middle name is "Help" and his full name is "Aloysius Help Snuffleupagus".
- Missed Him by That Much: In his early appearances, he'd wander off before anyone other than Big Bird could spot him, leading to speculation that he was BB's Imaginary Friend.
- Not-So-Imaginary Friend: For Big Bird. Everyone assumes that Snuffy is imaginary and even Big Bird thinks this at one point, but they are convinced otherwise later on.
- Only Known by Their Nickname: His real name is Aloysius Snuffleupagus. Even though almost everyone on the series refers to him by his nickname, his mother usually refers to him by his real name.
- Precocious Crush: Pre-dating the Elmo and Gina plot (see above), he had a crush on Maria for a while.
- Real After All: He is revealed to the adult cast 13 years after his debut, in order to encourage kids to be more honest with their parents. It was an emotional experience for the characters and actors.
- Satellite Character: Expectedly only talked to Big Bird due to being his Not-So-Imaginary Friend at first. After being proven Real After All, he began interacting heavily with other characters and having family members introduced.
- Shrinking Violet: The reason that none of the adults ever saw him was because of his shyness. He seems to outgrown this after being revealed.
- Performer: Richard Hunt
- No Celebrities Were Harmed: He is based on Placido Domingo.
- Put on a Bus: He was dropped after Richard Hunt's death in 1992, but continued to appear in recycled segments until 1998. He made a cameo in a 2009 episode, on the front cover of a book bearing Hunt's name.
- Jim Martin
- It Was a Gift: Well, he likes to deliver things to other characters. He once tried to give Elmo a sign that reads ABCDEFGHIJKLMNOPQRSTUVWXYZ. Elmo ended up singing the famous song originally sung by Big Bird. At that point, Big Bird and the kids told them that it's not a word, It's the alphabet.
SAM the Robot
- Jerry Nelson (occasionally Caroll Spinney)
- Broken Record: S.A.M. will tell anyone who is around him that Machines Are Perfect... except he'd always get stuck so he'd say "Machines are perfec-are perfec-are perfec-are perfec..." until someone hits him.
- Do-Anything Robot: Efficiently, on the other hand.....
- Fun with Acronyms: His name stands for Super Automatic Machine.
- Percussive Maintenance: In his debut appearance, he arrives on Sesame Street (he meant to go to Mulberry Street), asserting repeatedly that "machines never make mistakes; machines are perfect are perfect are perfect." The humans have to thump him hard to make him stop repeating the phrase, for which he thanks them.
- Put on a Bus: Mysteriously stopped appearing after the seventh season, although he returned for the tenth
- Tin-Can Robot: S.A.M. looks like giant tin can. This being Sesame Street, of course, he still has googly eyes and a bowtie.
- Vanity License Plate: He has one on his back that says "ABC-123".
Sammy the Snake
- Jim Henson
- One-Shot Character: He never appeared outside the song.
Shelly the Turtle

He is a friendly but a slow moving turtle.
