Well, what are you waiting for? DESCRIBE!

Odd Squad is a live-action kids' Edutainment Show that airs in Syndication on various networks, two of the most prominent being PBS Kids and TVO Kids. Created by Tim McKeon and Adam Peltzman, it premiered on November 26, 2014.

The show has four Rotating Protagonists across two seasons, who are all agents that work for Odd Squad, an organization run exclusively by kids that investigates and fights anything strange, weird, and especially odd. Both seasons focus on Precinct 13579, which operates out of Toronto.

Characters include:

• Agent Olive, a 12-year-old Shell-Shocked Veteran who is suffering from trauma of an unknown type due to an incident surrounding her former partner. As a result, she is a hardheaded, serious, and tightly-wound agent who prefers work over play.
• Agent Otto, a 10-year-old Cloudcuckoolander Investigation agent and one of Precinct 13579's newest hires. Olive's partner, he serves as her Living Emotional Crutch and her best friend who is often a little airheaded but knows how to have fun where she does not.
• Agent Oscar, Precinct 13579's resident Lab Director. Klutzy and goofy he may be, but he is known as a legend within Odd Squad history for being the first agent in the Science department of the organization and for inventing the concept of combining gadgets to make entirely new ones.
• Oprah, more known by her title, Ms. O. The almighty leader of Precinct 13579 who rules it with an iron fist, a hot temper, and a hell of a juice addiction that won't quit.
• Agent Olympia, an 11-year-old Genki Girl who is a fresh graduate of the Odd Squad Academy. She is a severe Workaholic whose greatest aspiration is making her co-workers happy. Which, of course, includes...
• Agent Otis, Olympia's partner and another new hire to Precinct 13579. For someone who is introverted with a bit more going on underneath the surface, he has more of a level head about him and frequently keeps his partner in line.
• Agent Oona, Oscar's apprentice and eventual successor who, while just as much of a silly kindhearted genius as her mentor, is also just a tad unhinged.

The show has since branched out into a franchise, with merchandise and numerous other media. For information on those, check the Franchise page.

Full episodes can be viewed here for those living in the United States. TVO Kids's official YouTube channel also has most episodes from all three seasons available for Canadian viewers.

The PBS Kids YouTube channel also has a playlist for the show, which includes the Odd Squad Healthy Habits videos as well as full episodes and clips. invoked (You might want a VPN to view all of these.)

Don't confuse this with The Fairly Oddparents episode of the same name, the children's book series by Michael Fry, or the former name of the hip-hop group Coughee Brothaz.

Tropes:

A to M

• The '80s: When Oprah and O'Donahue were agents. One of the episodes showing their time is 80's themed, complete with the clothes, slang, and hair.
• Abnormal Ammo: For kid-friendliness. Egregiousness is tied between the teddybearification launcher and Baby Orson taking down Odd Todd with a barrage of ice cream. (Yes, ice cream can cause a technical K.O. in this universe.)
  • More Edible Ammunition with Prof. Straw from Shmumberland, who shoots soup. Must not make Sealed Evil in a Can pun...too late.
• Absent Animal Companion: Ms. O gets a dog named Whoops in the episode "Puppet Show". He helps out in that one episode, and never appears again.
• Acting Unnatural: In "The Breakfast Club", Delivery Debbie is asked to help Odd Squad track down the Breakfast Club. She is extremely nervous, and when asked by the Club how much the pizza is, she first says it's $1 and then $10,000,000.
• Action Duo: Olive and Otto. Nearly all of the agents have a partner as well.
• Adults Are Useless: While there are some adults who have been shown to be intelligent, a majority of them are portrayed as dimwitted, if not downright criminal.
• Aesop: Mathematics, as well as science beginning in the third season, are the primary lessons. However, not all the aesops are math-based. Case in point: when Olive is telling Otto about Todd's backstory, Otto asks her why she calls him partner, even in past tense, to her clear confusion; then he explains partners help each other, like he and Olive, while Todd just helped himself. That same story also had a subtler one; when Olive wasn't getting things as fast as Todd did, he would insult and belittle her, especially if she tried to question him. In contrast, while Olive gets annoyed with Otto when he delays their missions, she never belittles him and regularly and openly shows she cares for him, having no problem with him contradicting her most of the time.
• Air-Vent Passageway: In "Oscar Strikes Back". If you had any doubts of Ms. O being a Pint-Size Powerhouse, she strikes out the bottom of the duct with her fists when she and Oscar get cornered by the brainwashed scientists.
• All or Nothing: The offer to Olympia at the end of the villain game show "Villain Always Win". She is enthusiastic and decides to continue playing. Oona and Otis are not thrilled with her choice.
• Anachronism Stew: What with dinosaurs, unicorns, the like and a futuristic headquarters.
• Animesque: Downplayed. The show does have a couple tropes that are commonly found in anime, such as Kaiju antagonists, Villains of the Week (although the show does have an extensive Rogues Gallery), agents calling their attacks, and even Boss Subtitles in one episode. However, that's about it as far as the anime influences go.
• Arc Number: 43. It's the badge number of ex-agent Odd Todd.
• Arc Villain: The Shadow is being set up to be this for Season 3, Mobile Unit. She is an Enfant Terrible who has an inexplicable grudge against Opal.
• Argument of Contradictions: Shown in "O is Not For Old" in which it's boys vs. girls in the fight for Ms. O's present. The two girls (Polly and Olive) want a bike; the three boys (Otto, Olaf and Oren) want a trampoline as a gift to give said boss. Thus leading to a fight where the two girls are chanting "BIKE! BIKE! BIKE!" and the boys are chanting "Trampoline! Trampoline! Trampoline!" It takes Oscar's nonsensical noises just to shut them up.
• Artistic License – Statistics: Oswald commits a textbook case of sampling bias in "Sample of New York" when asking 50 of 500 agents for their favorite food - all of them being babies.
• Athletically Challenged: In stark contrast to his partner Olive, Otto's skillset does not lie in sports. This is something he willingly points out to Oren in "Switch Your Partner Round and Round" when the agent is looking to insult him, and something that comes up as a plot point in "The O Games" during the eponymous event. About the only athletic thing Otto does well is dribbling a basketball.
• Attack of the 50-Foot Whatever: For odd values of "attack", in "Happily Ever Odd". Ronnie and Bonnie want to marry, but their best man Donnie goes through a number of transmogrification hijinks. By the end of the episode, they have to be content with the best best man Odd Squad could come up with in a short time: a large Donnie that towers over everyone and who is moved to tears by the wedding.
• Attention Deficit... Ooh, Shiny!: Justified in "And Then They Were Puppies": "We all need to stay focused!" This works about for one second, given that Odd Squad was turned into puppies.
• Awesome, but Impractical: An agent using the van as part of a taxi service is annoyed about Omar and Opal squabbling about whether they are a taxi service or an elite team of agents and exits mid-air with a hang glider...only to learn that opening the wings in the crammed van (as opposed to outside, in the air) is somewhat counterproductive. She still manages to get out anyway.
• Babies Make Everything Better: There are quite a few in the show, including Agent Orson and Baby Genius.
• Babysitting Episode: "Hold the Door", "Two Agents and a Baby", and "It's Not Easy Being Chill".
• Back for the Finale: Larry and Phyllis were absent for about half the season, but they came back in the Season 1 finale.
• Bad Luck Charm: "Show Me The Money". A nickel that shouldn't leave the lab was let loose when Otis and Olympia paid Delivery Debbie. As it is with money, it quickly circulated, causing havoc (and falcons) everywhere.
• Badass Adorable: The show's premise is an international agency of little kids in suits fighting evil. How is that NOT this trope?
• Badass Bandolier: Otto wears a bandolier filled with ice cream cones in "Undercover Olive".
• Badass in a Nice Suit: Most of the agents wear suits as their uniforms.
• Bag of Holding: In "Odd Beginnings: Part 1", Arctic Mr. O gives Opal and Omar a "Bag O' Machines", saying that while said machines may not be helpful on a case, the bag is nice to hold stuff in.
• Bait-and-Switch: With the audience, about Once per Episode. Usually it's Ms. O going to rip off some poor agent's head...only that she doesn't.
  • Especially this gem: "Dr. O?" "Here!" "You're not in this story!" "Copy that."
• Banana Peel: Nana Banana is a villain with the ability to fire bananas out of her hands. The floor of her lair is littered with banana peels, which causes Agent Olympia and the Stitcher to slide crazily when they race in an attempt to grab the Stitcher's notebook in "Who is Agent Otis?".
• Batman Gambit: In "The Perfect Score", the agents are rated by the villains. One villain ruins Olympia's perfect "10" score by giving her just a "1" to lure her into his trap. She promptly calls him out on it, arguing that his brilliant plan could only work because she is such a great agent and is a Determinator. The idle talking buys her time to set her defenses against his superpower.
• Be Careful What You Wish For: In one of the training videos, Opal demonstrates the 60-second power nap. What Could Possibly Go Wrong? Well, it's ample time for Omar to inadvertently botch up usage of the microwave. He almost manages to tame the haywire machine...almost.
  [Omar stands with a big dish of popcorn]
  Opal: Can I have some?
  [cue popcorn falling from the ceiling]
• The B Grade: When Olympia receives the satisfaction reports from the villains she has stopped, she receives 10s from all but one. This so incenses her that she sets out to track down who gave her the one. It turns out that the villain actually thought she deserved a 10, but gave her a 1 to bait her into a trap.
• Big Damn Heroes: Agent Orson (despite being a baby) had helped Odd Squad out of jams several times.
• Big "NO!":
  • Olive gives one at the end of "Soundcheck" when Ms. O yells at her and Otto that playing "Gonna Add Four" added 4 of most things, and that they needed to play "Gonna Add Four" and "Take Away Four" at the same time, to which Ms. O yells "REMIX!" and begins to dance with Otto. Olive crawls away from the scene. Also counts as a Skyward Scream subversion.
  • Otto gave a cutoff one in "The Zero Effect" when the 0 was taken away from Polly's sign.
  • These keep repeating in "O is Not For Old" when Olaf kept insisting he wanted a potato to give to Ms. O as a present.
  • "Crime at Shapely Manor" had Otto issuing one when Lord Rectangle supposedly "destroyed" the cake by throwing it to the floor. Later turns into a Big "YES!" moment.
• Binary Suns: At the end of "Soundcheck", Ms. O shows Otto and Olive a slideshow of what resulted from playing the song "Gonna Add Four". The first slide shows a sunset with five suns.
• Birthday Episode: Orla has her 500th birthday in "Orla's Birthday."
  • Ms. O also has her birthday in "O is Not for Old", complete with Surprise Party.
• Bitch in Sheep's Clothing: President Obbs who only appeared in "Oscar Strikes Back". When the episode begin he gave the scientists pins (except Oscar and Oona), and started off as a friend of the hero. But then... he revealed how jealous he was of how little attention his department got, and revealed that the pins were mind-control devices, and got control of the agents, forcing them to help him take over Odd Squad, just so he could get attention.
• Bookends: The first and last episodes of Season 1:
  • In the first episode, Olive casually says "Quiet day at the squad" in response to what looks like chaos in headquarters. In the last episode, she says the line again, this time in response to all the odd creatures that got unleashed when Otto mistakenly opened all the doors in headquarters.
  • Also in the first episode, Otto invites Olive to his tenth birthday party. In the last episode, Otto is bemoaning how he'll never see Ms. O and Oscar again; but he feels better when Oscar points out that everyone was invited to Otto's upcoming eleventh birthday party.
• Bound and Gagged: Polly Graph by a spider cat.
• Brand X: The Schmumber's line of products, developed from Ms. O's old friend Yucks Schmumbers^note probably derived from "Numbers Schmumbers", making it a Stealth Pun graces everything in the show from juice boxes to magazines.
• Bread, Eggs, Breaded Eggs: In "Slides and Ladders", Oswald is walking through a hallway and points out the Cheese Room, the Cake Room, and the Cheesecake Room.
• Breaking Old Trends:
  • Season 3 deviates from the norm of focusing on two Investigation agents, an Odd Squad Director, and a Scientist, instead focusing on four agents who are collectively known as the Odd Squad Mobile Unit along with Oprah, who is the Big O. The second half of the season switches things up and replaces Opal with Osmerelda Kim and Oprah with Orpita, who is the Little O.
  • Season 4 focuses on an Odd Squad precinct in the United Kingdom. It has a core cast of seven characters, including two Investigation agents, a Security officer, a Scientist, an Odd Squad Director, a Food and Beverage worker, and an agent in an entirely new department, though the two Investigation agents, Orli and Ozzie, are the main characters.
• Breaking the Fourth Wall: Aside from Oscar and his Training Videos, Welcome to Headquarters Videos and Odd Reports, there have been a few cases of this trope throughout the show. Ms. O is a great example with her recruitment videos and website-promoting videos.
  • In "Blob on the Job", Olive does this twice and Otto once, both agents saying "no blob".
  • There have been times where the characters try to avoid breaking the fourth wall, as in "Agent Obfusco".
  • In "Switch Your Partner Round and Round", Olive does this multiple times.
  • This jewel:
  Agent Oscar: (throws himself into flashback stance)
  Beat
  Agent Olive: Uh, I think your story's this way.
  Agent Oscar: Oh. Right. (start flashback)
  • It gets to epic proportions of meta in a recruitment video:
  Oswald: I joined because the fourth wall never should be broken. [he waves to the camera] Hi there, people watching this!

• Bucket Booby-Trap: In "Now You Don't See Me", Odd Todd rigs a bucket booby trap to one of his clues so it dumps invisible ink over Otto, turning him invisible.
• Buffy Speak: In "Two Agents And A Baby", Marty Marmalade is confused about the flying "carriage rocket thingie" the agents arrive on. (So are Olympia and Otis. Baby Genius always surprises.)
• The Butler Did It: In Crime in Shapely Manor, when the butler, maid, and Miss Triangle turn out to be triplets and steal the cake.
• Calling Your Attacks: Agent Oksana shall give a distraction. "Distraction! Distraction!" "Get back here!" (Hey, it worked. Did you doubt it?)
  • Many agents have a tendency to call out the name of the gadget they conjure up from Hammerspace just before they fire it.
  • Some villains. such as the Sticky Sisters, tend to do this as well.
• Calvinball: "Villains Always Win", technically, has only one rule: Villains Always Win. But to ensure that, a whole load of rules are made up on the spot so that Olympia doesn't end up winning.
• Camera Abuse: In "Training Day", the pie-nado starts spattering the edges of the field of view with meringue as Olive gets closer to its source.
• Car Meets House: Otto and Oscar come to Olive's rescue by driving an ice cream van through the wall of a warehouse in "Undercover Olive".
• Catchphrase: Almost everyone has at least one. Some examples include:
  • Olive says, "Let's go!"
  • Oscar saying "Hey guys!"
  • Oona saying "Howdy-do!"
  • Ms. O gets three. "Olive, Otto, in my office, now!" Or... "Well, what are you waiting for?! Go!" Or... "Something very odd has happened."
  • Dr. O's "What's next!" and "I'm a doctor!"
  • Olaf: "POTATO!"
• Chainsaw Good: The Oscarbots who did a massacre on innocent oranges. (But think of the alternative, Ms. O not getting her juice box...)
• Character Blog: Olympia has a 20-episode YouTube series called OddTube. Hosting duties are passed to Orla for 12 more episodes.
• Chekhov's Boomerang: In "Happy Halfiversary", Otis never even unpacked his Door Stopper-ish Odd Squad manual. Thus he is in deep emotional trouble when he finds Olympia sent him a Halfiversary gift, and he has none. Even worse, after he nearly gets zapped by Mr. Lightning to get his autograph as a present, that wasn't the only anniversary tradition he flunked, and he has to fetch an Odd Squad badge while risking his life. Rule of Three does him in, and he's out of ideas. When the great gift showdown comes, he ruefully takes out his manual to explain, but before he can eloquently excuse himself... "A mint-condition Agents' Manual, still in its shrink wrap?! This is the best Happy Half-iversary, 31st-iversary, Friday Felebration EVER!"
• Chekhov's Gag: In "Three's Company". Ms. O must temporarily leave her office, causing Oona to have a nervous breakdown (specifically, she loses her grip on gadgets, causing them to fall and break). This incidentally helps to solve the last malfunction in the office.
• Chekhov's Gun: Plenty in various episodes, but one of the most notable is the wedge from Omar's Bag-O-Machines in "Odd Beginnings", which is always pulled out first and is of no use...until the Grand Finale of the episode.
• Chekhov's Skill: Otto, many times. E.g. when his mastership of paper flyer folding helps to catch the villain of the week.
• Children's Covert Coterie: The show focuses on the eponymous organization, whose agents are all children and fight oddities using gadgets and mathematics. Standing in their way is a Rogues Gallery of odd villains who love to cause oddness by any means possible, ranging from a Musical Assassin to an Improbable Weapon User who uses jam as a weapon. The organization has been around during the cavemen times and is very high-tech.
• Christmas Episode: "Reindeer Games".
• Chuck Cunningham Syndrome: An odd example concerning the Math Room, which is both a room and a character. As of Season 2, the Math Room no longer appears, and the agents consult snazzy smartwatches instead.
• Clap Your Hands If You Believe:
  • The Nice-inator (a rude person desperately wanted to be nice, called Odd Squad, and got a treatment with this). Otis decidedly did not tell him it was just a flashlight.
  • In "Orla's Birthday". Opal is constantly making up villains who "stole" the van (in reality, Omar and Oswald take it to Chicago to collect birthday surprises for the eponymous agent) in order to distract Orla. Said villains turn out to be real people who are more than happy to help keep Orla's surprise birthday party a secret.
  Opal: How are all these people real?!
• Cloudcuckoolander: Potato. I mean, Olaf. Has a moment of The Cloudcuckoolander Was Right in the voting episode: "Bicycle" and "Trampoline" are tied as birthday present for Ms. O, and it needs short before physical violence to make Olaf change from "Potato" to break the tie. Of course it turns out Ms. O would have liked the potato best...
• Cloth Fu: Oscar takes down a group of mind-controlled Scientists with his labcoats in "Oscar Strikes Back".
  Ms. O: [holding an ever-increasing heap of lab coats] How many labcoats do you wear?
  Oscar: Seventeen. I get chilly easily.
• Clownification: Clown-itosis is a disease where the victim slowly turns into a clown and runs away to join the circus. The episode "Into the Odd Woods" focuses on Omar contracting the disease after hitching a ride from a group of clowns, with Orla keeping an eye on him while Opal and Oswald go to the titular Odd Woods to gather ingredients to make a cure.
• Cobweb of Disuse: In "Haunt Squad", fittingly. Only a few minutes after the whole Maintenance team ran away screaming. Knowing the HQ bestiary, spiders working overtime are not that surprising.
• Color-Coded for Your Convenience: Each department is represented by a color: yellow for Maintenance, green for Science, teal for Medical, blue for Security, red for Investigation, and purple for Management. These colors reflect on characters' uniforms as well (Investigation agents having red ties, Management having purple shirts, etc.).
• Comically Missing the Point:
  [Olive produces a pineapple from Hammerspace for a weighing problem]
  Otto: [flabbergasted] Where did you get that thing from?
  Olive: Hawaii.
  • In the episode "Behind Enemy Mimes", Ms. O, while on a mission with Olympia and Otis, says that O'Donahue likes his orange juice hot, his eggs raw, and he always leaves a clue behind. This is what Olympia has to say:
    Olympia: His breakfast sounds awful!
• Company Cross References: Has happened twice in the series.
  • In "The Void", one of the things Omar learns in order to be similar to Opal, Orla and Oswald is how to speak Spanish. He does this by watching a short clip of Mac and Sammy communicating in Spanish from Playdate, which is produced by Sinking Ship Entertainment. Doubles as an Actor Allusion subversion, as Millie Davis played Molly in that show, but does not appear in "The Void."
  • "Slow Your Roll" has Opal, Omar and Orla come face-to-face with a creature known as a Madmelodia, which looks strikingly similar to the alien creature seen in Endlings, a show also produced by Sinking Ship Entertainment. This is yet another Actor Allusion subversion similar to above — Michela Luci, who plays Orchid, also plays Tabby; however, she does not appear in the episode.
• Confronting Your Imposter: In "Flawed Squad", Shapeshifter changes into Agent Olympia in an attempt to throw off the Odd Squad agents who waiting outside the craft room door for the villains. When she opens the door, she finds herself facing Agents Otis and Olympia. She angrily asks why she had to turn into Olympia of all agents.
• Continuity Nod:
  • The episode "The Trouble With Centigurps" seems to get a few of these, most notably in "Worst First Day Ever".
  • "Switch Your Partner Round and Round" has one to "Blob on the Job". Not surprisingly, when "Odd Squad: Against the Odds" was airing, these two episodes were paired together and shown back-to-back.
• Conviction by Counterfactual Clue: "The Deposit Slip-Up". By long Odd Squad must have learned now that 8 is not the only symmetrical number; 3 is also symmetrical. Their plan to trick Symmetric Al nearly folded on this detail.
• Cool Car: The Mobile Unit Van from Season 3. The fact that it's Bigger on the Inside is just one thing.
• Cops and Detectives: More detectives than cops, but the kids' appearances hint this trope.
• Correlation Implies Causation: Done in "Who is Agent Otis", by both parties of the big trial.
• Couch Gag: During the slideshow part of the intro, after the slide with just the first agent's partner (Otto, Otis, and Orla, Omar and Oswald), there is a slide of a random object, with the first agent (Olive, Olympia, and Opal) describing what it is.
• Courtroom Episode: "Disorder in the Court" and "Odds and Ends": Olive and Otis are tried, respectively.
• Cover Version: In-universe. Of course, for a two dollar budget you don't get "Soundcheck". Only their cover band "Soundcheck-ish". And since due to unforeseen Noodle Implements complications the budget had to be cut into half, they had to hire Soundcheck-ish's Evil Twin (evil as in their talent).
• Covered in Gunge:
  • One of the promotional commercials has a woman being consistently covered in blob.
  • The slime fight — training for fighting the dragon in the Potato Room — in "Where There's a Wolf, There's a Way" counts too.
  • "It Takes Goo To Make A Feud Go Right", naturally.
• Crazy-Prepared: In "Wax On Wax Odd", Orla overhears two villains chatting about how they will cause oddness 450 years from that day. She notes it in her calendar, and 450 years later, she invokes Chekhov's Skill by teaching her teammates a few mundane-sounding tricks that prove to be helpful in defeating oddness.
• Crazy Workplace: The titular organization is full of oddities that range from balls of fluffy creatures that multiply when exposed to light, to floating people, to glowing people, and lots more. In spite of it fighting oddness, however, it is ostensibly odd itself — episodes feature threats such as a popcorn flood, tornadoes made out of pies, and characters gaining lemon and pickle heads, among a slew of other things.
• Crowd Panic: Played straight, but also parodied - panic shmanic, the customer won't leave without his hotdog at the stand. And sauce. And a serviette. And...And...
• Cute and Psycho: Some of the cast can be a little off their rockers at times, such as Oona and Orchid. (Especially Oona. Don't say we didn't warn you.)
• Cute, but Cacophonic: The agents sometimes get very loud, and hearing all of them shout at the same time can be very harsh on the ears, especially the girls who can sometimes get very high-pitched. An In-Universe example would be Oona while in a fly's body, which pitches her voice up to near Alvin and the Chipmunks levels.
• Deceptively Cute Critter: Centigurps are cute fuzzy spherical creatures that lure curious agents into freeing them from their confinements and allowing them to multiply rapidly by exposing them to light. From there, they gravitate to objects in the shape of spheres. About the only thing that makes them not so cute are their disturbingly human-like eyes, which are hidden under their fur.
• Deliberately Monochrome: Because the color setting button of reality was set on black and white, as Otis quickly observed.
• Department of Redundancy Department: "Teaming up with Teamwork Together as a Team", a series of agent interviews across all three seasons.
  • There's also "Teams working with teams together as a team together" that concludes every agent interview.
• Desperate Object Catch: In "Disorder in the Court", Odd Todd throws a shrunken building to distract the agents while he and Shapeshifter make their escape. Olive catches it an inch from the floor in a Diving Save.
• Disney Death: Olympia turning into a cake in "Extreme Cakeover", which prompted Otis to let out a Big "NO!" before the helmet, which she was carrying at the time and which fell on her, activated, and she turned back into a human.
• Distant Finale: Played with in "Total Zeroes" when a still-young Ms. O tells the elderly Olympia and Otis how the story of the Zero siblings ended; it's not the season or show finale.
• Dramatic Drop: Happens Rule of Three style when Odd Todd returns. Olive and Otto tell Ms. O, who drops her juice box. Oscar comes in carrying a box of marbles, which he drops when Ms. O tells him Odd Todd is back. Oscar is ordered to tell the other agents that Odd Todd is back, prompting shocked gasps and a wide array of noises accompanying the items various agents were carrying when Oscar yelled the news being dropped. The foursome in the office wince throughout.
• Droste Image: The seal of Odd Squad.
• Easily Forgiven: For mind-controlling the Odd Squad scientists and attempting to take over the world, Obbs is thrown out of Odd Squad. And gets the suggestion to join Odd Todd's gardening program. Resocialization is surprisingly Serious Business in the Oddverse!
• Edible Ammunition: In "Undercover Olive", Olive, Otto and Oscar attack the assembled villains by flinging ice cream at them. Otto is wearing a Badass Bandolier of ice cream cones.
• Eccentric A.I.: Oscar's Oscarbots are just as eccentric and ditzy as their creator, right down to copying said creator's physical tics and mannerisms due to being Ridiculously Human Robots. In "No Ifs, Ands, or Robots", Oscar's repair on an Oscarbot goes awry when Orchid ends up scaring Oscar, causing the Oscarbot to become corrupted so it shoots a beam at a gadget to turn it into a juice box, and the rest of the episode is spent trying to stop it from turning people and objects into juice boxes. Within its defectiveness, it follows a specific pattern of going by tens, meaning that whatever it attacks has a number ending in 0 on it (10, 20, 30, etc.).
• Edutainment Show: Natch — it's a PBS Kids show after all.
• Emerging from the Shadows: Baby Genius and Rivka often do this, combined with Stealth Hi/Bye.
• Emotionless Girl: Oksana, Precinct 13579's chief cook. She has a Creepy Monotone as well.
• Enemy Mime: "Behind Enemy Mimes" features mimes as villains who despise being referred to as clowns.
• Enemy Mine: In "Villains in Need are Villains in Deed", the agents team up with Jamie Jam, Mr. Lightning, and Noisemaker to stop an evil robot from destroying the city and the villains' secret evil headquarters.
• Enfant Terrible: In a universe were odd-causing adults cause chaos to the world, these kids prove to be worse than all of them combined. A general rule of thumb is that if a villain is a kid, they'll have a personal connection to Odd Squad.
  • Odd Todd turned into a villain in "Training Day" when he got bored of being an Invincible Hero and thought the city could use more oddness.
  • President Obbs turned out to be another one in "Oscar Strikes Back" when he got tired of never getting credit for the agents' work, and tried taking over all Odd Squads just to get attention.
  • The father of them all has got to be Ohlm, who wanted to gain the role of the Big O, and enviously tried to destroy the universe just because he didn't get the role in the squad he wanted.
  • The Shadow is definitely shaping up to be one. It's not revealed how she turned to villainy as of yet, but she has a vendetta against Opal and is a tech genius, able to hack, reprogram, and control the Odd Squad Mobile Unit's van. Her assistant, Brutus, also has moments of intelligence despite being mostly idiotic.
• Entertainingly Wrong: In "The Sandwich Project", the Mobile Unit has been zapped into sandwiches, and in order to turn them back to normal, the Big O and the other agents need to know who is who (the easy part) and the order they were zapped in. If the Big O hadn't been so alert, Odd Squad would have forgotten an essential clue: Just because Omar filmed the whole stuff with the camera on his helmet, it doesn't mean he was zapped last. He was zapped third, and Opal then picked up the camera.
• Episode Title Card: The trademark manila folder with the episode name and with Ms. O reading it. Earlier episodes had the writer(s) and director on the title card before showing them on the bottom right when the episode began (or in the case of Season 3, the bottom left).
• Everyone Calls Him "Barkeep": Subverted in "First Day", there is a dentist whose name is literally "Dentist." Double subverted, there's also a woman whose name is Marie, but she says she pronounces it as "Crossing Guard."
• Everything Is an Instrument: In "Music of Sound", Orla, who is disguised as the "studio manager" of the Villain People, constantly sabotages their equipment, but they always find new stuff in the studio to use instead (like trashcans).
• Evil Laugh: Xena and Xavier have one. The Creepy Monotone definitely doesn't make it better.
  • Odd Todd has a notable one as well.
• Evil Twin: The Cold Open clients have this problem in "And Then They Were Puppies".
• Exactly What It Says on the Tin: The "Total Zeroes" siblings. Brother Zero is not very happy being an ultra low-class villain and thinks of opening a flower shop instead...called "The Flower Shop".
• Exact Words:
  • Party Pam - "Eat my food, and I'll make you a balloon!" Probably the food produced too many gases...
  • And then we have "Behind Enemy Mimes". The room where the mimes plan their evil scheme is tracked down. Olympia and Otis, knowing Ms. O's penchant for forceful entry, remind her that she could simply use the door handle. Which she does - by boxing a giant hole into the door and opening the door from the inside.Given this was a hotel room, possibly locked, and they had to Race Against the Clock to stop the weapon from being activated, her sense for drama was clearly the correct decision.
  • As by a friendly agreement of Odd Squad and their villains, Odd Squad may ask a caught villain exactly "20 Questions" that he has to answer truthfully. However, he's allowed to also tally questions that are clearly rhetorical or blatantly stupid, and happy to answer those.
• Extra-Long Episode: Most episodes are about 11 minutes, but some episodes, especially those important to the story arc, like "Training Day" or "O is Not for Over," are double the length.
• Extended Disarming: In "Failure to Lunch", Olympia hands over all of her gadgets when to the restaurant owner when she goes out to lunch to show she is off-duty. Later, the owner and his brother have to search through a huge stack of gadgets in the cloak room in search of something to undo the oddness in the kitchen.
• Extreme Omnigoat: Randall from "O is for Opposite is a minor example. He happily chews away on Delivery Doug's clothing. (And lays eggs. Somehow.)
• Face Your Fears: Orla is afraid of Tube Travel (which is somewhat justified, as the prospect is too "modern" for her), but quickly gets the hang of it after she overcomes her fears.
• Faction Motto: "E Weirdibus Bizarreum, Strangeus Non Normalur".
• Fake-Out Fade-Out: In "Put Me in Coach" it seemed like the episode ended when Orielle and Oriele "won" the competition for who got to take the case... only for Coach O to say they won the round, not the contest, and that it was a 2 out of 3 competition. He puts them in the penalty box for jumping to conclusions and partying early.
• Fake Static:
  • Ms. O invokes this in "Trials and Tubulations" in order to cut the conversation short with Olive and Otto regarding Sector 21.
  • In "Running on Empty", Opal pulls this on the Big O, of all people. And it actually works.
• Fangirl: Olive does this in "Bad Luck Bears", as well as...well, any time she interacts with the Bears.
  • She also does this in "O is Not for Over" shortly after getting promoted to Ms. O.
• Fantastic Caste System: Downplayed but still present in some episodes. The organization has a hierarchy in place comprising of at least 60 departments. Of those 60 departments, only seven are prominently featured in the series: Management, Investigation, Security, Medical, Science, Transportation/Maintenance, and Mobile Unit. The sides that each department's symbol has determines their rank in the hierarchy, and the more sides a symbol has, the higher the rank. The show doesn't explore the hierarchy in depth, but episodes like "There Might Be Dragons" and "Dr. O No" carry some implications of it. What department an agent is in also reflects in their uniforms as well based on the color of the department's symbol (Ms. O wears a purple undershirt and purple necklace, Dr. O wears a teal labcoat, etc.).
• Fear-Induced Idiocy: During the Ring Toss section of the O Games, Otto begins to panic because he doesn't want to get hit by a robot princess. Not wanting to be disqualified, he goes from playing defense throughout the entire game to throwing all ten of his rings backwards in the hopes that he'll score some points. He quickly realizes that wasn't the best course of action and rushes to catch his rings before they can be stolen, but manages to get all ten rings around one robot princess, score 100 points, and be the first contestant to qualify for the final round anyway.
• Fearsome Critters of American Folklore: The badge of Odd Squad features a jackalope.
• Feeling Their Age: Orla. "You should have seen me when I was 300 years old!"
• Flashback Cut: Used heavily in episodes such as "The Perfect Lunch" and "Orla's Birthday". The latter episode has Omar, having enough of Oswald's flashbacks, cutting one short, with accompanying visual and audio effects.
  • Numerous ones occur in "Slow Your Roll". All of them are justified because the hacked van is steering into certain doom, and with it, the Mobile Unit themselves.
• Flying Books: The librarians, Oren, and Olaf fight a pack of them in "Dawn of the Read."
• Foreshadowing: Has its own page.
• Fourth Wall Psych: In "Good Egg, Bad Egg," the agents are in a possibly dangerous position. Olympia says something along the lines of "We'll be safe, right? I mean, there's so much left in the season." Ms. O is confused until Olympia clarifies she meant one of the four seasons.
• Free-Range Children: Albeit an unusual sort, considering they're children who work jobs like adults do.
• Freudian Excuse: Why does Fladam hate cubes? Because he stepped on one as a child.
• Friendship Moment: Quite a lot of them, actually, considering friendship is one of the show's Central Themes.
• Friendship-Hating Antagonist: Many villains in the franchise despise friendship and teamwork, both of which are Odd Squad's modus operandis. Odd Todd is a stellar example — whereas Otto is a kind and caring partner and friend to Olive who serves as her Living Emotional Crutch, Odd Todd is the polar opposite, being cruel, being abusive, and flexing his superiority over Olive any chance he gets.
• Gadgeteer Genius: This is the purpose of the Science department, to make gadgets.
• Gentle Giant: Logan the Ogre, who manages to double-subvert this trope in his first appearance.
• Give Me a Sword: Ms. O says a variant of this to O'Malley in the Season 1 finale.
• Grade-School C.E.O.: Ms. O herself is the all-knowing example of this.
  • Grade school employees are the entire base of the Odd Squad. It doesn't help that Ms. O was once an Odd Squad agent herself, and a fruit stand vendor before that.
• Group Hug:
  • Olive, Otto, Oscar and Ms. O have one at the end of "O is Not for Over".
  • Otis, Olympia, Oona, and Ms. O also have one at the end of "Odds and Ends".
• "Groundhog Day" Loop:
  • "Drop Gadget Repeat" has Oona stuck in a time loop of only a few minutes. She ends up bringing Otis and Olympia into the loop as well, which forces them to figure out how to get out of it in time before it restarts.
  • Also "6.00 to 6.05", where Olive and Otto undo the Big Dino Breakout.
• Growing Wings: At the end "Where There's a Wolf, There's a Way", Werewolf Olaf suddenly grows wings for no reason at all.
• Grub Tub: As Oscar explains in one "Welcome to Odd Squad" video, Precinct 13579 has quite a few swimming pools filled with substances other than water, including one that is filled with ice cream.
• Had the Silly Thing in Reverse: In "Flawed Squad", Shapeshifter grabs Father Time's staff and attempts to use it to freeze Odd Squad. Father Time points out that she is holding it the wrong way 'round just before she activates it and freezes all of the villains.
• Hammerspace: Odd Squad agents can access a variety of odd situation-specific gadgets simply by reaching behind their backs. It's shown to be an ability that is taught to agents, which takes time to master.
• Harmless Villain: Played straight with some (like Noisemaker) and averted with others (like Fladam). Occasionally their gadgets have harmful side-effects, but Oscar is well equipped for that. They even work together with Odd Squad sometimes to clear their (silly) names.
• A Head at Each End: The designer of Odd Squad's swimming pool was apparently an example, according to Oscar's discourse on symmetry. A drawing of the architect shows him with two torsos attached end to end.
• Heh Heh, You Said "X": A kid-friendly variant is used when Dr. O gets the Sillies; overlaps with What's a Henway?.
• Heel–Face Revolving Door: Todd became a villain when he saw flaws in how Odd Squad was run, and by Season 2, he became a gardener on the side of good. However, in "Mid-Day in the Garden of Good and Odd", he is forced to fight the urge to go back to villainy when he holds a gadget in his hands. Otis is able to help him turn back to his normal, reformed self, and by "Odds and Ends", he makes strides in his reformation.
• Heel–Face Turn: Otis used to be a villain, but after his duck brothers tried to destroy the world, he ran away and joined Odd Squad.
• Hero of Another Story: Ms. O in "Hands On A Desk Chair".
• Hero's Evil Predecessor: Otto's predecessor Odd Todd is the main villain of Season 1.
• Heroic BSoD: Otto goes through a brief 2-second one in "Zero Effect" when he realizes that if he and Olive are unable to restore the missing zeroes, he will turn 1 instead of 10 years old the next day. Olive is eventually able to calm him down.
  • Olive also goes through a brief one in "Agent Obfusco". On the contrary, Otto is the one that calms her down.
  • Olympia in "Olympia's Day", though it's more of her hallucinating than having a BSOD. (It's actually a common occurrence known as "slipping into mathness".)
• Hey, That's My Line!: In "There is no O in O-Bot", Ms. O says this when Xena steals her "well, what are you waiting for" line.
• Hiccup Hijinks: The pilot episode "Zero Effect" starts with Olive and Otto helping out a woman who has exploding hiccups, where something breaks every time she hiccups. They give her a cure, and report back to headquarters, but she hiccups before drinking the cure, breaking the cup with the cure among other things.
• Highly-Visible Ninja: "The Ninja Situation", naturally. Even worse (for the ninja) is that he is a show-off; when he sees a log on a stand he has to chop it, giving Otis the time to set up his impersonation of him.
• His Name Really Is "Barkeep":
  • On the show "Villains Always Win", when Game Show Gary addresses the studio audience consisting of a single person. Said person happens to be named "Studio Audience".
  • In "First Day", Olympia and Otis have to rescue Hopkins, a dentist and a crossing guard who have mysteriously started floating. Olympia and Otis keep referring to all of them by their occupation (including Hopkins, who is referred to as "Businessman"), leading to this exchange:
  Hopkins: Does it bother anyone that they haven't asked us our names?
  Dentist: My name is "Dentist", so...I'm good.
  Crossing Guard: I'm Marie, but I pronounce it "Crossing Guard".
• If I Had a Nickel...: It's subverted in "No Ifs, Ands, or Robots".
  Orchid: If I had a nickel every time someone said that, I would have...no nickels.
• I'll Never Tell You What I'm Telling You!:
  • The villains of the Breakfast Club.
  • The Shadow's assistant, Brutus, does this at one point in "Slow Your Roll".
• I'm a Doctor, Not a Placeholder: Dr. O has done this at least a couple times.
  Dr. O: I'm a doctor, Ms. O! Not a party planner!
  Dr. O: I'm a doctor, not a babysitter.
• I'm a Humanitarian: Subverted. In "The Sandwich Project", Shelly Catessan, a villainess, turns the Mobile Unit into sandwiches. They are taken to the van and remain there until the case is solved. An especially insensitive agent helping the Big O eats a sandwich that is initially believed to be one of the OSMU agents, sending everyone into a panic. It's then revealed that he's eating a sandwich he brought from home, spurring the Big O to make a new rule: no eating sandwiches until the case is solved.
• Impersonation Gambit: Odd Squad fakes a whole town to trick Symmetric Al, who stole Ms. O's jetpack. They also have Delivery Doug impersonate the vault's security guard.
• Improbable Food Budget: Oksana requests expensive items (such as gold bars) to make food for the Squad. It turns out to be justified.
• I Need a Freaking Drink: Ms. O sometimes needs a freaking juice box.
• In a World…: The tagline for "Odd Squad Saves the World": "In a world gone strange".
• The Infiltration: Oswald and Orla go to Villain University to find out more about Mr. Unpredictable. While Orla is able to pull it off well, Oswald nearly exposes the pair to numerous aspiring villain students — and eventually does, when his badge phone goes off during class.
• Instantly Proven Wrong:
  • In "Dr. O: Party Time, Excellent": "I absolutely can bake my own cake!" Cue Smash Cut. Well, at least it was a recognizable attempt.
  • In "Shapely University": The precinct boundary goes exactly through it, and thus two Odd Squad teams were sent. "I'm sure [our bosses] will sort this out in a reasonable and civilized manner." Cue phone to superiors and the two Directors squabbling like little kids.
  • In Opal's interview video, there's this gem:
  Opal: We're an elite team of agents! [whispering to the viewer] But it's not like I would ever say that out loud to people.
  [cue Clip Show montage comprised of her saying just that]
• Incredibly Lame Pun: Otto, as expected, gives one in "Crime at Shapely Manor". Olive manages to one-up him with a pun of her own by the end of the episode.
• Incredible Shrinking Man: Otto, who ate a Shrinking Potato. (Hey, Olaf marked it with "O". Your problem.) By Rule of Funny, you already can guess what happens when the effect is undone (ahem) with a Growing Potato.
• Insistent Terminology:
  • The Eggmobile, insofar it's a Running Gag that all characters complain that it's just a normal car and neither egg-shaped nor egg-colored. (It's just the owner selling egg sandwiches.)
  • As per a Running Gag in "Two Agents and a Baby", marmalade is not jam. Marty Marmalade gets very miffed if one confuses that.
• Internal Affairs: The X's. If what we saw of them is a fair statistical sample, the Big O should seriously consider internal-affairing them.
• Interrupted by the End: In "Running On Empty", Opal starts her great speech about OSMU and how it's an elite team of agents who fight oddness, just to get repeatedly cut off for some reason or another. When she tries to do it again at the end of the episode, a Smash Cut ensues that ends the episode.
  Opal: Seriously?!
• Invisibility: In "Now You Don't See Me", Odd Todd uses invisible ink to all of Odd Squad, except for Olive and Otto (who were out of HQ at the time), invisible. Olive and Otto have to track down Todd and take back the Re-visible-inator gadget he stole, which is the only way to reverse the effect.
• Invisible Parents: Enforced by Tim McKeon and Adam Peltzman, the show's creators, who have stated that not showing characters' lives outside of work is a deliberate choice done to keep up the theme of equality (since what families a character has can determine their financial status, etc.) However, this policy has since been tossed thanks to "Odds and Ends", where Agent Ohlm hopefully is Grounded Forever at the behest of his parents.
• Is There a Doctor in the House?: There is a song about Doctor O that features this line.
  Is there a doctor in the house? Call Doctor O! And she's a specialist in everything that you don't know!
• Jerk with a Heart of Gold:
  • Agent Olive. Despite being cynical at times, she cares for her friends and her co-workers.
  • Ms. O as well, which is most prominent in Seasons 2 and 3.
• Jokers Love Junk Food: Otto, known to be a Cloudcuckoolander, has quite an appetite as well as a sweet tooth for donuts in particular. "Oscar and the Oscarbots" has him being upset about being dragged away from the Donut Room by a frantic Oscar (and him getting excited about the Cake Room when he's informed of its existence), while "Hold the Door" has him wanting to take Ori to the Donut Room instead of the Lab with the counterargument that "donuts are a good foundation for life!"
• Kid Detective: The entire cast of the show, save the people who need help.
• Labcoat of Science and Medicine: Take a guess which departments wear these. (Science and Medical)
• Lampshade Hanging: In "Now You Don't See Me", the invisible ski coach (It Makes Sense in Context) asks Olive and Otto:
  "Have you guys ever noticed you do a lot of math?"
• Laser-Guided Karma: Served with a dash of Irony to Halfsie Harriet. She stole Ms. O's voice because her usual voice is very high-pitched and people don't take her seriously with it. At the end she's at least nice enough to help sort out the mayhem in HQ (many things are voice-activated), but that doesn't avert the punishment fitting the crime: Oona gives her a new voice...which happens to be a female squirrel voice.
• Laughably Evil: Let's face it, some of the villains on the show are more comical than evil.
• Laugh Track: In-universe. The weekly oddness victim suffers from canned laughter accompanying everything he says - even if not remotely funny. Odd Squad's solution is brilliant as always. Headphones.
• Leader Wannabe: Orzack, to the annoyance of Ms. O. He calls himself a Mr. O and tries to take command of her office. No one takes him seriously.
  • Downplayed for Agent Olive. While it's very subtle (up until it's outright stated in "Disorder in the Court"), her primary desire is to be an Odd Squad Director in the same vein as Ms. O, but she doesn't actively try to take over her position in any manner. She gets her wish temporarily in "The O Games", and permanently in "O is Not for Over".
• Leaning on the Fourth Wall: The show is no stranger to being meta, but this moment from "The Ninja Situation" speaks for itself.
  Olympia: If Sheila could see me now!
  Oona: I don't think we're doing that anymore.
• Leeroy Jenkins: Orla, in spades. She tends to not think ahead and instead dives right into danger.
• Lethal Chef: New York Ms. O, whose employees quit due to what she was serving for lunch: every food mixed in at once into a boiling, brown, foul-smelling mess. It manages to stink up the drains and create a hole in the ground.
• Lies, Damned Lies, and Statistics: Odd Todd uses a classic to demotivate Polly Graph and sell his sour-lemonade-with-side-effects. He defends his lemonade with bar charts that have no labeling.
• Literal Metaphor: A large staple of the franchise's humor.
• Literal-Minded: In an "Odd Squad Needs You" commercial, Ms. O says that "I need a break!" Cue her doing karate training by breaking a plank.
• Literally Shattered Lives: Subverted. In "Extreme Cake-Over", most agents turn into cakes. (Hey, that's not more odd than anything else on this show.) In her fight against the cake virus, Agent Olympia (as a cake) ends up as a mess on the floor and everybody is horrified. Of course, it's a kids show - after the virus is sucked out of her remains, she returns to normal totally unscathed, and being cake-ified seems to be a somewhat odd, but not painful experience. At least not as painful as Oona's cake puns...
• Little Miss Badass: Ms. O is amazingly strong and a good fighter. Most of the female agents could be seen as this as well.
• Little Miss Snarker: Olive, Orchid, Ms. O, and sometimes Oona tend to slip into this. Olive is a more prominent example, as she gives out snark often.
• Loony Fan: Jeremy from, well, "Jeremy", who is creepily obsessed with the Squad. Fortunately, his invoked Fan Myopia saves the day because he knows all the answers to the van security questions.
• Loophole Abuse: In the O Games, Odd Todd is allowed to do the ring throwing for the other agents. This of course makes no sense whatsoever (Oscar closes the hole for the next discipline) and is used by Odd Todd to kick out a random agent from the competition.
• Lower-Deck Episode: "Friends of Odd Squad". Ms. O has to attend a conference and puts Hopkins, Mr. Fonts, Party Pam, and Logan the Ogre in charge. With the explicit instructions of "sit down, don't touch anything, don't do anything". Yeah, that's a recipe for disaster.
• MacGuffin: The MacGuffin-inator in "The Ninja Situation" is one. Doubles as a neat Lampshade Hanging of the trope as well.
• Makes Just as Much Sense in Context: "Running on Empty" has a moment that's bizarre even for this show's standards. Agents Opal and Orla use quart containers to carry water in order to refill their van's fuel tank, which runs on water. They already have three full quarts of water, and need to get one more from the water well. But then, a group of random people (known as "feral watercolor artists") come out of nowhere, steal all of Opal's empty quart containers, and run off into the distance, yipping all the way.
• Manchild: Just about every adult in the series is immature and cowardly. They easily fall for a new oddness-solving team, completely unaware they were just hiding the oddness. Any sensible person would check and see if the oddness was actually fixed before honoring the newbies.
• Man-Eating Plant:
  • There's one in "A Case of the Sillies" that Oona and Ocean encounter. Oona was lucky that it just got her arm and it succumbed to Music Soothes the Savage Beast. It was large enough to eat her whole.
  • There is a giant Venus flytrap in the Creature Room at Odd Squad headquarters. Oscar nearly gets eaten by it in "First Day".
• Market-Based Title:
  • The show is known as Organisation Super Insolite to French-Canadians. However, Canada as a country uses the original name of Odd Squad.
  • In Norway, it goes by the name of Kode Tropp O.
  • Sweden refers to it as Ett fall för KLURO.
• Maybe Magic, Maybe Mundane: "Haunt Squad". Otis and Olympia disagree when it comes to the question of if there's a ghost in HQ. In typical Odd Squad fashion, the answer is both.
• Medium Awareness: There are a lot of meta moments, and moments of numerous characters being aware that they're characters on a TV show. "O is Not For Over", the Season 1 finale, has a prominent example of this, with Olive suggesting to the director of Bizarre Brigade that it "might work better with kids", followed by Otto going to fix the problem (with one of the actors having literally lost her head) and using the correct terms for an actor on set.
  • Ms. O is another example. The Odd Squad Agent's Handbook reveals that she was approached by Philo T. Farnsworth, the inventor of television, in 1927 regarding making a TV show. She suggests that he try again in 87 years, or in 2014 — the same year the show premiered.
• Memory Match Mini-Game: The episode "Put Me In, Coach" opens up with Oprah playing a "flip two tiles at a time and try to find matches" game, only with pictures of villains. She has three matches, but doesn't match either card she flips over next (Fladam and Odd Todd), causing her to give a growl of frustration before and Olympia and Otis walk in.
• Midas Touch: Eating fifty bananas per day gives you Bananaitis - everything you touch turns yellow. (Don't tell Siniestro!)
• Mirrors Reflect Everything: In "Perfect Score", Olympia uses her mirror suit to reflect Freeze Ray Ray's freeze ray back at him, freezing him inside a block of ice.
• Mirror Self: The Cold Open from "Failure To Lunch". A woman is annoyed by her mirror reflection who is still stuck in a fascinating magazine article when she wants to go to work. Agent Olympia says she can't solve that problem...but her mirror reflection can.
  • Also "O is for Opposite", where Ms. O falls into a mirror, releasing her odd twin.
• Mirror Universe: Downplayed. Negative Town has negative house numbers and its citizens have negative attitudes, but Dark Is Not Evil.
• Mix-and-Match Critters: The spidercats, and quite a few other creatures.
• The Mole: Agent Ohlm was acting like a fool so he could secretly help the villains take over Odd Squad without drawing suspicion.
• The Movie: Featuring a uniting of both the Season 1 and the Season 2 cast.
  • World Turned Odd as well, where Otis, Olympia, and Oona accidentally undo every odd case Odd Squad's ever solved.
• Multi-Part Episode: "Reindeer Games", "Crime at Shapely Manor", "6:00 to 6:05" and a handful more others.
• Mundane Utility: In one of the commercials, Oona uses the elevator to illustrate negative numbers. On Floor -2 she fetches a stick, on Floor 2 she fetches a marshmallow, and then it goes down to the lowest floor, -5 — a cave with a dragon who toasts her marshmallow with its fire.
• Musical Episode: Downplayed; in "The Cherry-on-Top-inator", Oona is pleased when Olympia and Otis start telling their story about the eponymous device, as she thinks it is going to be a normal story. Instead, it turns out to be a musical about them going undercover in a diner to spy on Puppy Master and Evil Knight. However, the entire episode isn't a musical - Ocean tells his story as a cartoon, Orchid tells hers as a sock puppet theater and Ohlm tells his in a Film Noir style, so it quadruples as a Medium-Shift Gag.
• Mysterious Past: Olive's old partner Todd. Otis's past is set up to be the main mystery of Season Two. "Who is Agent Otis?" reveals the backstory. He was raised by evil ducks. When they plotted to destroy the world, Otis quit and, with the help of Ms. O, joined Odd Squad.

N to Z

• Never the Selves Shall Meet: Or else. In "Back to the Past" and "Ms. O Uh-Oh", of course.
• New Season, New Name:
  • Season 3 is known in full as Odd Squad Mobile Unit.
  • Season 4, likewise, will be known as Odd Squad UK.
• Nice Job Breaking It, Hero:
  • In "Who is Agent Otis?", Ms. O initially assigns the job of getting the notebook of villains to Xena and Xavier because she knows they'd mess it up. Olympia goes behind Ms. O's back and retrieves the notebook, only for Xena and Xavier to reveal that Otis used to be a villain — the reason why Ms. O didn't want the notebook in the first place. Otis is tried in court and fired from Odd Squad along with Ms. O.
  • In "Odd Beginnings", Omar posts a selfie of himself and Opal with 44 clover emojis on Oddstagram, attracting the attention of the Sticky Sisters, leading them to try and find the 44 leaf clover as well.
  • Zig-zagged in "Who Let The Doug Out". Fladam and Lady Bread constantly bicker who is the oddest of them all, even in Ms. O's office. Delivery Doug's great speech about the union of eggs and mayonnaise makes them bury the hatchet. However, Doug isn't a hero, technically speaking; he is generally portrayed as antagonistic.
• Nice Job Fixing It, Villain: Noisemaker is very prone to this, as he Cannot Keep a Secret.
• No Budget: In-Universe. The great leave party of Dr. O has a budget of $2. Hilarity Ensues, especially at the end - as you could have expected, Dr. O loves the random ersatz stuff.
• No Indoor Voice: Ms. O, Party Pam, Coach O, Opal, and Omar all have a tendency to yell a lot.
• Non Sequitur: At the beginning of every episode, the show starts off with the main agent introducing themselves through slides (Olive in Season 1, Olympia in Season 2, Opal in Season 3), then their partner (Otto in Season 1, Otis in Season 2, Omar, Orla and Oswald in Season 3), then saying something that has nothing to do with anything while showing a slide related to it before getting back on topic. For example, "This is me, Agent Olive. This is my partner, Agent Otto. This is a dream I had the other night. But back to Otto and me." Doubles as a Couch Gag as mentioned above, as the non-sequitur changes in every episode.
• Now Allowed to Hug: Otis is largely averse to shows of affection like hugs, opting for polite handshakes instead. In the Season 2 finale, he starts to give a handshake to Oprah, only for her to refuse it and tell him to "bring it in." He willingly obliges, joining in a Group Hug with his coworkers.
• Number Obsession: Number hogs are people who are obsessed with a particular number and end up taking said number from various objects. The episode "Zero Effect" has Glenn, a cupcake shop owner, inadvertently become one in order to promote his "one million billion trillion" flavors of cupcakes. He steals zeroes from a mass variety of things, including Otto's 10th birthday invitation.
• Obfuscating Stupidity: "Odds and Ends" reveals that Ohlm was pretending to be dumb so he could take over Odd Squad.
• Obstructive Bureaucrat: Olympia and Otis must get their paperwork properly done to become "Agent of the Month", lest Baby Orson gets the honor. The agent processing the closed cases is extremely unhelpful. Justified; if you are very clever with Foreshadowing, you could have guessed it was Baby Orson in disguise.
  • Also the X's, Xena and Xavier, demanding budget cuts while living a life of luxury, which doesn't sit well with anyone.
• Offscreen Moment of Awesome: This series loves this trope.
  • In "Best Seats In The House" While Olive, Otto, Oren and Olaf were fighting over special chairs. Oscar, Ms. O and Octavia were running a top-secret mission, that involved Oscar getting his hair cut. Then towards the end, we see Octavia walking down the hall with a cat in her hands, and getting a lot of applause. Too bad we didn't see too much of them in action.
  • "Life of O'Brian": Otto taking down a laser chicken without Olive's assistance. Usually he's the goofy one.
  • "O Is Not for Old": So you want to see Ms. O single-handedly defeat all the oddities by herself, with nothing but her bare hands? Sorry, it happened offscreen. Admit it, you wish that wasn't an Offscreen Moment of Awesome.
  • "Three's Company": So, before the main plot occurred, Olympia and Otis had to restore the moon and put it back in orbit, the closest we see to them doing the case is a photograph.
  • Again in "The-Cherry-On-Top-Inator" when Olympia and Otis told a musical story about them going on an undercover mission to spy on The Puppy Master and Evil Knight. Apparently, they were planning on destroying the world, only to be foiled by Olympia and Otis.
  • "Other Olympia": Olympia (no, not the Olympia we know who's a central season 2 character) and Orzic (who used to be two of Ms. O's assistants) just finished a year-long case involving a villain known as the Sandman. Needless to say, both of them were very happy to finally be back. This would explain their extremely long absence.
  • In "Happily Ever Odd", Donnie changes into something else when eating various foods, first turning into a donkey and winning the Donkeyball League which Coach O invented, and then into a rabbit, being sent to the moon by Oona. We see only a few stills from the adventures, which all take place in just a few hours.
• Older Than They Look: A flashback to Ms. O as a rookie agent in the 80s has her in period fashion and hair, but no younger.
  • Ms. O's flashback in "Fistful of Fruit Juice" shows her before she joined the Squad in the 1870s, and she's still no younger.
  • This also applies to O'Donahue.
  • And Orla from Season 3, who is a few hundred years old.
• Old-Fashioned Fruit Stomping: In the episode "The Odd Antidote", Olive and Otto obtain one liter of Loganberry juice by having the latter mash Loganberries with his feet while Logan the Ogre plays the violin beside him and Olive collects the juice.
• Old-Timey Bathing Suit: Ms. O wears one in "Not So Splash".
• One-Steve Limit: Averted for many characters.
  • There's Glenn the cupcake man and Glenn the drink purveyor.
  • There's also Bob, the guy who is in Otto's head, and the middle name Bob used by Kayley and Haley.
  • There is a Dr. O, not to be confused with Ms. O.
    • The episode "Invasion of the Body Switchers" has a Professor O.
    • The head of a nearby city's Odd Squad division is a Mr. O.
  • There are at least three Tonys: the bouncer, the Soundcheck member, and the chef.
  • Olympia is both the name of one of Ms. O's assistants and the female protagonist of the second season.
    • This particular example is lampshaded in one episode.
  • There are 2 Orlas: Olympia's friend from the Academy, and one of the protagonists of season 3.
  • Otis is the name of Olympia's partner, Todd's dog, and the new agent at the end of "Other Olympia".
• Order Versus Chaos: The Squad agents are primarily concerned with making things normal, not better, although this usually ends up helping people by default. Seeking power or stealing stuff is only a secondary goal for most of the villains; for most, causing chaos and defying the Squad is much more fun.
• Overcrank: Justified in "Slow Day", where a few citizens suffer from Slo Mo. It's also lampshaded - one of the citizens begins to juggle, prompting Olympia and Otis to get into a discussion whether objects they touch go into Slo Mo too. Olympia theorizes it's a "force field situation".
• Overly Long Gag: Agent Orchid gets into a staring duel with Oona in "Oscar Strikes Back". Too bad it's not Oona herself, but a wax figure of her, so Orchid is out of luck.
• Overly Long Scream: Otto gives a big one when he finds out he's been cut in half. His screams gradually decrease though, to the point where he gives a faint pleading one when Olive refuses to go find Baby Genius.
• Overnight Age-Up: Agent Olive is in big trouble when the Flip-Flopinator changes her from 12 to 21 years old. Since adults are not allowed to work as agents in Odd Squad, Ms. O has no choice but to fire Olive.
• Passionate Sports Girl: Olive is obsessed. It's one of the few things she will visibly lose her cool over.
• Paper People: Olive, temporarily, by Fladam's devices.
• Parental Bonus: The Season 2 episode The Breakfast Club introduces an incompetent villain trio called... well... The Breakfast Club. Both of which are named after the 1985 film of the same name. A clever reference, one only older audiences would pick up on.
• Perfectly Cromulent Word: Used during an "Odd Squad Needs You" commercial from Ms. O: "Yes, I'm talking to you, the one who always understands me. Sneeblegoop-moobiedorp!"
• Pie in the Face: Omar to Orla. To his excuse, he caught Clown-itosis. She later throws a pie in his face, which turns out to be the cure.
• A Pirate 400 Years Too Late: Pirates are a common oddity in the world of the show, and most are amiable when it comes to interacting with agents.
  • In "The Curious Case of Pirate-itis", Olive contracts the eponymous disease when she helps a pirate cross a busy street and begins to slowly turn into a Pirate Girl. By the climax of the episode, she's nearly full pirate, with the manner of speaking, the outfit, and the behavior to match.
  • In "Ocean and the Fly", while looking for a cure to turn Oona back into a human from her fly form, Ocean and Oona visit a pirate in a cave, who has a treasure chest fill of gold and pearls, and also wants to start a butter company. He asks Ocean and Oona to help him pick a label for his new butter, and once they pick one, he allows them to take a pearl from his treasure chest. Later on in the episode, he is shown at the grocery store attempting to sell his new butter to customers but failing, and once he sets his eyes on Ocean and Oona, he becomes enraged and takes off after them.
• Pirate Girl: Agent Olive, who suffered from pirate-itis. Technically a subversion, as she turned more into a pirate boy, complete with mustache.
• Platonic Boy/Girl Heroes: Basically every set of partners that are the opposite gender.
• Platonic Life-Partners: See above.
• Plucky Girl: Most of the female agents. This especially goes to Olive and Olympia.
• Poisonous Person: Logan the Ogre can be found nearby the Loganberry tree as well as in Sector 21, a dangerous forest filled with dangerous odd creatures. He has skin that is poisonous to the touch, which makes his habit of taking selfies with people very hazardous.
• Pokémon Speak: Each Oscarbot can only say his number.
• Pool Scene: In "Skip Day," Dr. O shows Otto a video of Olive swimming at the Odd Squad pool. Since Olive has the skips, she's still wearing her Odd Squad uniform.
  Polly Graph: Looks like she skipped the step where she put on a bathing suit.
  • The end of "Not So Splash", sort of. Ms. O couldn't wait any longer for Olive and Otto to fix the weather problem, so she flooded headquarters.
• P.O.V. Cam: "Sir". The camera follows his mishaps when going to HQ to be turned back to normal and is shot from a first-person POV.
• Prank Call: From Sillies!Dr.O. Of course it's no great idea to make a prank call from a ten-meter distance. Or so Olympia and Otis think...until they run into plastic foil, set up by Sillies!Dr. O herself.
• Punny Name:
  • Symmetric Al.
  • Also, Polly Graph. (A polygraph is the advanced version of a lie-detector test.)
  • The evil (as in talent and alignment) band Villain People.
• Pun With Pi: In the episode "Training Day", after a pienado is released, an alarm sounds, with a voice reciting the digits of pi.
• Put on a Bus: This happens to multiple characters throughout the series, as their actors were aging and couldn't reasonably play children anymore. Particularly noticeable was that the actors for Oscar and Dr. O had gotten significantly taller between Seasons 1 and 2.
  • Olive and Otto are promoted to Ms. and Mr. O of another headquarters in "O is Not for Over."
  • Oscar goes to lead the Science Department in "Oscar Strikes Back."
  • Dr. O leaves for the "Odd Squad Space Station" in "Dr. O: Party Time, Excellent."
  • Olympia, Otis and Oona are absent in Season 3.
  • Mathroom/Carol is completely absent in Season 2 onwards.
  • Opal leaves the Mobile Unit in "End of the Road" to travel the world with her sister instead.
• Quirky Doctor:
  • Dr. O from Seasons 1 and 2 is the comically serious Head Doctor of the Medical department at Precinct 13579, whose humor comes from being deadpan and serious enough in personality to contrast everyone else's eccentricity in an organization where eccentricity is the norm. She constantly reminds everyone that she's a doctor regardless of whether they're aware of it or not, drinks unicorn tears as a favorite food (when she's not using it in cures), and according to "Extreme Cakeover", she doesn't even have a birthday, citing that it is a medical condition she has.
  • Olly, Dr. O's replacement who debuts midway through Season 2, is crazy enough to scare the resident Cute and Psycho Scientist Oona out of her wits with her actions — handing Oona random food and changing her undershirt without touching her once, having a strange vendetta against Precinct 13579's cafeteria workers, and having an original birth name of "New Dr. O" before getting it changed. Unlike her predecessor, she is far from competent in her job, often Comically Missing the Point when it comes to properly measuring ingredients and relying on her (one-sided) best friend Oona for every medical-related thing under the sun when she doesn't work in the Medical department and thus has little knowledge of the cures for odd illnesses. By the end of Olly's debut episode, she is transferred to the Food and Beverage department, where she fares much better.
• Raised by Wolves: In the season 2 finale, Otis reveals that he was raised by ducks.
• Rank Up: In "Odds and Ends", Ohlm gets promoted to Mr. O after Oprah is fired. However, he gets demoted and fired from Odd Squad due to being evil. Then, the Big O announces that since he has to go to kindergarten, Oprah is now the Big O, with Orson becoming the new boss of Precinct 13579.
  • Olive and Otto get promoted to Ms. O and Mr. O in "O is Not for Over".
• "Rashomon"-Style: In "Recipe for Disaster", Olive and Otto explain to Ms. O why a case went wrong and created a vortex, each in their own way, and each telling a significantly different version of events. The villain Rainbow Robyn then adds her own version of events, which is probably closer to the truth.
• Read the Freaking Manual: Otis ends up not knowing what a Halfiversary is because he never read his manual in "Happy Halfiversary".
• Record Needle Scratch: Constantly used in "Music of Sound". Funny enough, it fits well with the theme of the episode.
• Reluctant Monster: Many. Best example may be Logan, Keeper of the Loganberries. He's a bit scary, but constantly averts the Threshold Guardians expectations:
  Olive: We have to get back to headquarters and-
  Logan: NONE SHALL LEAVE THIS PLACE!
  Beat
  Logan: Until we take a selfie together!
• Red Is Heroic: The main characters, the Investigation department, are associated with red.
• Refugee from TV Land: In "How to Interrogate a Unicorn", Olive and Otto investigate when characters start coming out of books and invading the library.
• Rewatch Bonus: Play close attention to whenever Ohlm does something really stupid and ditzy throughout Season 2; He's trying to destroy Odd Squad for not being made the Big O upon graduating the Academy, and being The Ditz is just an act so he can sabotage the squad without drawing attention to himself.
• Riddle Me This: The riddle of the Guardian of the Rocks: "What is heavy, and solid, and makes a very nice paperweight?" One guess what the answer is...
• Rock–Paper–Scissors: In the beginning of "Totally Odd Squad", Olive, Otto, Oscar, and Ms. O play this to see who gets the last jellybean. The winner is Ms. O.
  • In "Undercover Olive", all the villains in town have a rock-paper-scissors contest to see which of them gets a map of the Odd Squad tube system. Since one of the villains is sick, Olive, being the best RPS player on the Squad according to Ms. O, goes undercover as the sick villain and wins.
• Rookie Male, Experienced Female: Olive and Otto. He's new to the squad, while she's already had a former partner and experienced a betrayal and pienado.
• Rotating Protagonist: Olive and Otto are the main characters of Season 1. Otis and Olympia are the main characters of Season 2. Opal, Omar, Orla, and Oswald are the main characters of Season 3, entitled Mobile Unit.
• Rotten Robotic Replacement: Heavily downplayed with Omega. He's quite good at pulling wrong scientific hypotheses out of his backside, he blocks the Noisemaker's "Happy Birthday" attack with pizza, and when he selfdestructs like all good robots, he just goes "poof" and is gone forever. But of course, Olympia's "gut feeling" for solving the case was right.
• Running Gag:
  • "You know, when you said Eggmobile, I really thought it'd be shaped like an egg."
  • There are also season-long running gags: Season 1's "If Sheila could see me now", Season 2's toast, and Season 3's Esmeralda Kim.
• Sarcasm Mode:
  Ms. O: I have an idea. Let's all stop working and talk about how much you love the Bears.
  Olive: Really?!
  Ms.O: NO!!! We have a case to solve!
• Sarcastic Clapping: Agent Oren does this in Blob on the Job. It only takes a few seconds for Olaf to steal Olive and Otto's blob container and make off with it.
  Oren: Well done. You caught the blob fair and square. Too bad Olaf grabbed it while you were watching me clap!
• Saying Sound Effects Out Loud: Oscar does this in "Bad Luck Bears" when he's scanning the players for 13s as well as in "Zero Effect" describing the number hog. However, in a Behind the Scenes video, Sean Michael Kyer (who plays Oscar) says that his character's gadgets do not contain any speakers necessary to emit the sounds, so he makes the sounds himself.
  • Olive does this in "Reindeer Games".:
  Olive: Oh, I always like to make a "ding" sound whenever I find a coordinate.
  • Another version is spoken later in the same episode by the same agent.
  Olive: Ring-a-ding-ding.
• Say My Name: "OSCAR!!!"
• Scare Chord: Fittingly, in "Haunt Squad". In the Cold Opening, a man is afraid to open his closet because one of these plays every time he gets close. Otis is also too scared, but Olympia gets all her strength together and rips the door open. It turns out to be a woman playing the cello who mistook the closet for a concert hall.
• Sdrawkcab Speech:
  • "20 Questions", courtesy of Backwards Bob (or Bob Backwards). Ms. O is affected, but she talks backwards so it cancels out.
  • Also done in an "Odd Squad Needs You" commercial by Otis.
• Self-Destruct Mechanism: Of course the Mobile Unit Van has one. Omar manages to hit that exact button when pressing random buttons in a training video. Luckily, he manages to stop the countdown in time.
• Series Mascot: A jackalope can be found on the automatic doors throughout the Odd Squad headquarters. A more close-up view is shown in the "Cupcakes" promo.
• Severely Specialized Store: In "Odd Squad in the Shadows", the Squad mistakes Mr. Sides for a supervillain. However, when they visit him, they discover he is actually a local businessman who runs a restaurant that serves nothing but side dishes. He later admits "this was a terrible business model".
• Shame If Something Happened: In "How to Interrogate a Unicorn", Olive is attempting to interrogate a unicorn. When the unicorn is uncooperative, Olive changes tactics, putting a bucket with a rainbow inside on the table and telling it that it would be a shame if something happened to it. The unicorn still refuses to comply, and Olive angrily knocks the bucket onto the floor, spilling the rainbow.
• Shell-Shocked Veteran: Olive is deathly afraid of pie, because her old partner, Odd Todd, unleashed a pienado that she had to stop. It didn't help that Oscar had to pull a Heroic Sacrifice, albeit nonlethal, so she could do so.
• Sibling Rivalry: The Confalones go from Bestest Friends to Shouting Match and back in seconds.
• Sinister Surveillance: A case of Watchers watching Watchers at the end of "The O Team". Luckily, said watchers all belong to Odd Squad, but it's still played as a bit sinister.
• Sir Verb-a-Lot: Odd Squad's pet goldfish, Sir Fish-A-Lot.
• Skyward Scream: Odd Todd does one in "The O Games" upon losing.
• Somebody Doesn't Love Raymond: When Agent Olympia discovers one supervillain has given her a 1 on her evaluation form, rather than the 10 she got from every other villain, she becomes obsessed with finding out who gave her the bad evaluation.
• Speak in Unison
  Olive and Otto: The directions are missing zeroes because zeroes are disappearing! Stop talking at the same time as me! YOU STOP!
  • Olive and Otto also tend to do this in general, especially when announcing the name of a suspect in a case, or in Ms. O's words...
  Ms. O: Only when they get really excited.
  • "Jinx" is the embodiment of this trope.
• Spoiler:
  • Rare in-universe example for "Olive and Otto in Shmumberland". Not very clever of Agent Otto to refuse getting spoiled, as Agent Olive, who knows the content of the comic (into which the two were zapped), can use her knowledge for their benefit.
  • Another in-universe example occurs in "Raising The Bar" — Opal shoots down some Flying Books (which can talk) and complains they are spoiling the endings of stories.
  • And yet another in "Music of Sound", where the band Villain People endlessly discuss which evil orders they should give their hypnotized audience. Spoiling the endings of things was one suggestion.
• Spy-Tux Reveal:
  • It's shown in The One That Got Away and World Turned Odd that Oprah and O'Donahue keep their suits on under their clothes. They strip the outfit off to reveal the suit when called upon.
    "I never took it off."
  • The inverse happens in First Day. Olympia thinks she's failed as an agent, so she strips off her suit to reveal her academy clothes.
• Squee: Olympia in general is very prone to this in multiple episodes as well as The Movie. In one Odd Tube video, she literally squees and explodes.
• Starter Villain: The Sticky Sisters are the antagonists of the Season 3 premiere. They later get defeated by the protagonists. The Shadow is the actual main villain of Season 3.
• Stepping Out to React: In "Bad Luck Bears", Olive and Otto are told that the entirety of the Burly Bears basketball team needs to be brought into Headquarters to be scanned for unlucky thirteens. Once Olive confirms that the team is coming to her Headquarters where she'll get to meet them, she calmly excuses herself and leaves Oprah's office through its glass doors. The camera then cuts to Otto and Coach Roberts before cutting back to her as she begins screaming out cheers, doing the Running Man dance, and even inviting other agents to celebrate along with her in spite of their unease.
• Sticky Situation: Naturally, the shtick of the Sticky Sisters. They would make better villains if they didn't high-five each other and stick to themselves all the time.
• Surrounded by Idiots: Most Odd Squad villains are harmless and inept anyway, but the incompetence of Shapeshifter's team storming Odd Squad HQ in "Flawed Squad" is astounding.
  • Olive has a lot of these moments in Season 1. Most of her reactions to things revolve around the incompetence and sheer idiocy of people around her, and it's gotten to the point where a Face Palm (her pinching the bridge of her nose) is a defining Character Tic for her.
• Swapped Roles: "High Maintenance". Unsurprisingly, maintenance of HQ is a living hell, as Olympia and Otis soon have to admit. And of course, what would be a HQ (even of the good guys) without a yelling Self-Destruct Mechanism...
• Swiper, No Swiping!: Very often, but what you expect from Harmless Villains who are Affably Evil? (Well, some of them, anyway...)
• Swiss-Army Appendage: The villain The Utensiler (and her sister) have hands that are giant Swiss army knives, allowing them to manifest whatever utensil they might require, up to and including a vacuum cleaner. However, in the case of The Utensiler's sister, her hands no longer function as hands and she requires someone to open doors for her.
• Taken for Granite:
  • In "Dance Like Nobody's Watching", this happens to Olive, who jumped to conclusions and on a tile that triggered Oscar's safety system. (It was reversible, no surprise.)
  • In "Oona and the Oonabots", a creature called the Stone-Turner has turned nearly everyone in Headquarters to, well, stone.
  • And again in "The Thrill of the Face", where the ancient Piedro de Guerrero runs rampant. It has the ability to turn anyone into stone if one of its lasers hits them.
• Talking in Your Sleep: Oswald does this in "Down the Tubes" when he manages to fall asleep from exhaustion on a family's table after arriving at their home, which is Tube Station 5. He later does it at the end of the episode when he rides through the tubes.
• Teen Superspy: Or 'Pre-Teen Superspy' in this case.
• Teleporter Accident: Oona switches bodies with a fly in "Ocean and the Fly". Luckily, she is able to talk in this state, although it's grating Helium Speech.
• Temple of Doom: In "Odd Beginnings". It's an old abandoned Odd Squad HQ, which guards the legendary 44-leaf clover, and has death traps as well as Orla, the clover's guardian. Of course, it ends up collapsing at the climax of the episode.
• The End of the World as We Know It: Only very narrowly averted in "Total Zeroes", when Sister Zero, with her new power of multiplying by zero (instead of adding it), zaps everything away until only a White Void Room remains. Having a Heel Realization, she seeks Odd Squad's assistance in making things right again.
• Theme Naming: The agents' names all start with O. Lampshaded by Otto in "The Potato Ultimato".
  Otto: How was I supposed to know? Every agent that works at Odd Squad's name starts with an O!
  • It's why former Agent Todd stands out.
  • Agents who are part of the X's have names that start with X instead.
  • The band Villain People consists of Ava, Eve, Ivy and Uva. (The latter name is Latin for "grape".)
• The Password Is Always "Swordfish": Oona always forgets the password to her lab computer. (The password is "3".) Just in case, she isn't able to solve the oh-so-complicated math riddle on her cheat sheet, she has a special keyboard with all keys being "3".
• The Stinger: In-universe, in Oksana's What-not-to-do-with-food educational video, after probably everybody already turned off after the overlong Credits Gag (consisting of everything being credited to Oksana). In brief, all aforementioned rules are null and void in case of a monster emergency.
• Thing-O-Matic: Most of the gadgets have names that end in "-inator".
• Tickle Torture: Dr. O (under the influence of The Sillies) tickles Otis to the point of tears. This gives Oona and Ocean the idea to use the same technique on the Squanzo Bonzo plant, of which they need tears from for the cure to heal Dr. O.
• Time Lapse: Olympia and Otis reverse the Slo Mo effect from "Slow Day", forgetting that all agents in HQ, who are still in normal time, now speed up ridiculously. Ms. O has no problem with that: "Think of all the extra work they're going to get done!"
• Time Stands Still: Father Time, featured in "Flawed Squad", has this ability, which leads to much discussing in the villain team which Time-Freeze Trolling Spree should be brought down on the heads of the helpless agents. Unfortunately talking is no free action; the effect lasts only one minute and can only be applied once a hour. Cue villains frantically trying to hide in the vast Odd Squad HQ area before the minute is up.
• Time Traveler's Dinosaur: Part of the crux of Season 3's Story Arc involves a group of villains who are looking to use the Golden Sundial for their own personal gain, planning to defeat Odd Squad through summoning creatures from past history such as dinosaurs. However, they don't manage to succeed due to the Mobile Unit's interference. In addition, while they're not there due to time travel, Odd Squad does house dinosaurs of all sorts of species, which have been shown to ally with them once or twice.
• To Create a Playground for Evil: The main goal of the villains. They don't really benefit from their crimes, they just seek to make the world weirder.
• Too Much Information: The trope name is spoken verbatim in "Sample of New York" by now-retired villain Polka Dot Pete, who realizes that Omar and Orla are not that interested in his personal life.
• Trademark Favorite Food: Oprah loves juice boxes and Olaf loves potatoes.
• Trapped in TV Land: Or in this case, computer land in "Not OK Computer". Mostly the same...only in a computer you can download a cat virus named "Cat Virus". And a dog virus because they'll never learn. Which even manages to escape. Luckily, he's cute and harmless.
• Transparent Tech: Played with. It's not entirely clear whether the show takes place in the future or not, with the Odd Squad Agent's Handbook only suggesting it takes place sometime in the 2010s. However, the titular organization is very futuristic when it comes to its headquarters' designs as well as its gadgetry, some of which surpasses the inventions of Real Life, with Orpita claiming it is "at the leading edge of technology" in "Welcome to Odd Squad". The episode "Happily Ever Odd" in particular has Otis attempting to activate his smartwatch for help solving an equation, only for Oona to stop him by telling him that she doesn't want any of "that old-fashioned stuff in here" and project a transparent computer screen by shooting a beam into the air. Once the equation is solved, she blows on the screen, causing it to disappear.
• Troublesome Pet: The first and only appearance of Whoops, Oprah's dog from "Puppet Show", involves him snatching Oscar's bone-shaped gadget from his hands, which is needed to turn everyone back into humans. After a long chase through Headquarters, Otto, knowing that Whoops will only give up the bone if he has something else to chew on, offers himself as a sacrifice and tells Olive to throw him, but due to having been turned into a puppet, it has little effect. It takes Oprah giving Whoops a juice box for him to finally give up the gadget.
• Trust Me, I'm an X: Dr. O always tends to remind other agents that she's a doctor. See I'm a Doctor, Not a Placeholder above.
• Tube Travel: Agents travel by being "squishinated" into balls and then fired through a series of tubes to their destination.
• Turn in Your Badge: Odd Todd is fired from Odd Squad in "Training Day", for intentionally misleading Ms. O and Olive when attempting to find Tiny Dancer.
  • Olive is forced to do this in "Trading Places" when Odd Todd uses the Flip-Flopper-inator to turn her from 12 to 21; however, she returns to the force once the gadget is recovered and she is de-aged.
• Undercover Cop Reveal: O'Donahue infiltrates a trio of mimes and reveals himself by just wiping the make-up off and speaking. The Running Gag is the outrageous amount of unusually uninteresting sights he pulls on them to leave clues for Olympia, Otis and Ms. O.
• Unusually Uninteresting Sight: Quite a lot of the time. Justified in the sense that with that much odd happening, anything minorly odd won't really be noticed easily.
• [Verb] This!: When being attacked by evil copiers in "Friends of Odd Squad", Hopkins says "Copy this!" at one point when battling them.
• Villain Team-Up:
  • This happens in multiple episodes, but most notably in "Undercover Olive", when all the villains partake in a rock-paper-scissors battle to decide who gets the Odd Squad map.
  • Zig-zagged in "Villain Networking". The Shadow tries to unite all villains of the world, but every time she points out how much oddness they solved throughout the year, they begin to fight and blame each other. She finally manages to succeed when she focuses on how much oddness each villain group managed to solve in July (since that was a high point for them, before the Mobile Unit formed).
• Visual Pun: In "Undercover Olive," Fladam goes to the ice cream truck and orders an ice cream sandwich. Otto, Oscar, and Orson give him a scoop of ice cream between two slices of bread. This is actually what he wanted.
• Vomit Discretion Shot: In "Reindeer Games", a fellow agent had Ms. O try a worm cake. Though at first refusing, Oscar (sitting on the side) directs her. She then thanks the agent who offered it to her and runs offscreen to throw up and ask for a bucket.
• Weaponized Headgear: The villain Brad Hatter attacks people by throwing hats at them.
• World Tour: Season 3 sees the protagonists travel around the world as a Mobile Unit to solve odd cases.
• Weaksauce Weakness: The hydraclops is immune to all the heavy stuff Odd Squad comes up with. Wisely, Oscar has stored the ultimate anti-hydraclops weapon years ago: an overripe sock. The monster's keen sense of smell is his downfall.
  • The fact that you can knock out a ragtag bunch of villains by throwing ice cream balls at them surely counts too.
• We Can Rule Together: Odd Todd, Olive's old partner, repeatedly tries to get Olive as well as other agents to join his "Todd Squad".
• Weird Crossover: One promo released in the UK has Otis, Ms. O and Otis returning from a case to the world of Stranger Things — specifically, the Upside Down. This is despite the fact that Stranger Things is much more Darker and Edgier than Odd Squad, which is a Edutainment Show that, while mature at times, is for the most part lighthearted (not to mention that the former show is of the Horror and Science Fiction genres while the latter is a Work Com).
• Wham Episode: Has its own page.
• Wham Shot: Odds and Ends: Seeing Ohlm eat his yogurt with the proper side of his spoon, revealing he faked his idiocy.
• What Happened to the Mouse?: In "Puppet Show", Ms. O gains a new pet: an Australian Shepherd named Whoops. While Whoops was portrayed somewhat as the secondary antagonist of the show, he has not been seen or heard from since that episode aired.
• White Void Room: The titular void from "The Void" falls under this, due to the fact that it has two exits as well as a floor.
• Wicked Toymaker: Evil Teddy is a villain who steals batteries and turns teddy bears into evil robots.
• With Catlike Tread: Noisemaker wears a variety of instruments all over his body that makes sounds whenever he moves. When the gang of villains are attempting to sneak through Squad headquarters in "Flawed Squad", the others keep turning to stare at him because of the noise. He thinks it's because of his heavy breathing.
• World of Weirdness: Most of the minor odd occurrences which the Squad corrects don't have a villain, or even any sort of explanation, behind them. So long as it's fixed to the satisfaction of the client, nobody much cares why such oddness breaks out.
• Wounded Gazelle Gambit: Odd Todd in the O-lympiad against Dr. O. It works.
• Yoko Oh No: A non-romantic variant — Orla breaks up Soundcheck completely by accident in "Music of Sound".
• You Are Grounded!: In "Odds and Ends", Ohlm is grounded by his parents for trying to destroy Odd Squad.
• You Didn't Ask: Said by Omega, when Olympia and Otis find out he has a projection utility and they don't have to crawl into his cramped innards for doing research.
• You Say Tomato: The Squad solves the fight with "Tomeeeeeeeeeeeto!"
• Your Mime Makes It Real: In "Behind Enemy Mimes", the Enemy Mime trio is defeated this way at the end.
