(We're cool!) (Me, too!) Season 4
But they had a mean old principal Season 3
Who told them what to Season 3 S 4 (Blah, blah, blah, blah!)
So they got a Hypno Ring
And first they made him dance Season 4
Then accidentally, kinda on purpose
Turned him into Captain Underpants (Tra-la-laaaa!) Season 4
With a snap, he's the Captain
Not the brightest man Season 3 Season 4
And dont forget when he gets wet
Youre back where you began! Season 3 (Blah, blah, blah, blah!)
Put it all together
What could possibly go wrong?
Now this is the end of the Captain Underpants Season 4 song!
(By George Beard and Harold Hutchins.)
Tra-la-LA! Season 3 S 4
The Epic Tales of Captain Underpants is a DreamWorks Animation show based on the Captain Underpants novels by Dav Pilkey. Developed by Peter Hastings with narration from Sean Astin, this show follows the new adventures of Captain Underpants, a superhero who also goes by the name of their principal Mr. Krupp (voiced by Nat Faxon) created by comic-book-writers, pranksters, and best friends George Beard and Harold Hutchins (Ramone Hamilton and Jay Gragnani). There's also tattletale genius Melvin Sneedly (Jorge Diaz), The Ace Erica Wang (Erica Luttrell), Alpha Bitch Jessica Gordon (Dayci Brookshire), and Steve "Gooch" Yamaguchi (Evan Kishiyama).
The first few episodes tend to center on George and Harold creating a comic book whose main villain would inadvertently become the Monster of the Week. However, as season 1 progresses, an overarching plot becomes evident, which leads to this formula being mostly abandoned (at least, the comics and the villains aren't quite as connected as they were previously).
Premiered on the Netflix streaming service on July 13, 2018. Season 2 premiered February 8, 2019, while season 3 premiered on July 19, 2019. Season 4 is called The Epic Tales of Captain Underpants in Space! and was released on July 11th, 2020.
The Epic Tropes of Captain Underpants:
- Abusive Parents: Krupp's mom, Bernice. She calls him a disappointment, and when he did badly in his fourth grade talent show, she passed out rotten fruits and vegetables to the other kids to throw at him! Mother of the Year, everybody
- Actor Allusion: Right before fighting Captain Underpants, Splotch claims "There can be only one!" This is a reference to Clancy Brown's previous role in Highlander.
- Actually Pretty Funny: Bo doesn't mind that he was portrayed as a villain in one of George and Harold's comics.
- Adapted Out: Edith the Lunch Lady from the film (not to be confused with Miss Edith Anthrope, Mr. Krupp's secretary), is notably absent, since the series is based on the original books rather than the film.
- Advanced Tech 2000: All of Melvin's inventions, just like in the books, follow the naming template of Somethingotron (or -ator, or etc) 2000.
- Agitated Item Stomping: To show Mr. Krupp how mad he is, Mr. Meaner begins jumping up and down on his cap and continues doing this while Mr. Krupp demonstrates how mad he is by shaking a metal cabinet and yelling at the top of his lungs.
- Alpha Bitch: Jessica is a downplayed example, obsessing over her appearance (specifically her haar) and mistreating her friend (Other Sophie). Mr. Krupp calls her "the mean girl with the hair" in episode 12.
- Ambiguous Situation: Why and how Erica remembers the timeline where Mr. Krupp became a Corrupt Corporate Executive, even keeping an item from it, is left unexplained.
- It's implied in the Season 2 finale that she's been receiving guidance from her future self who was able to time travel back to ensure their successful future.
- Whenever Captain Underpants turns back into Krupp, the other kids are unfazed. Though its never explicitly stated if they know theyre the same person or not.
- An Aesop: The episodes usually have one, but without losing the charm of the show.
- Anticlimax: Season 1's finale ends with George, Harold, and Mr. Krupp kicked out of Jerome Horwitz Elementary, seemingly setting up Nothing Is the Same Anymore...And when season 2 starts, George and Harold's expulsion is reverted as their expulsion was deemed unlawful and Mr. Krupp quickly got rehired, albeit as vice principal.
- Arc Villain: Melvin arguably falls into this throughout Season 1, as almost every catastrophic event, along with several of the villains of the week, can be traced back to his inventions, his selfish desires, or both.
- In Season 2, he continues this role alongside his future self, Melvinborg, in the hopes of getting admitted into Eliteanati Academy at the expense of everyone else's education and happiness. But he does end up pulling a HeelFace Turn in the season 2 finale.
- Arson, Murder, and Jaywalking: In episode 5, Mr. Ree explains what T.E.R.D.S. is; a giant toilet created by the government to get rid of dangerous threats to mankind, such as poisonous chemicals, weapons of mass destruction
and envelopes.George: Envelopes?
Mr. Ree: Ever gotten a paper cut from one of those bad boys?
Mr. Ree: The whole jug?!!? You've doomed us all! That stuff's experimental, unpredictable, and kinda pricey!
- Mr. Ree also pulled this off earlier, in the same episode:
- Artistic License History: Everything with Ripticus.
- Attack of the 50-Foot Whatever: This happens twice in the Season 2 finale, courtesy of Melvinborgs nanobots. First its Melvin near the end of Part 1, then its Captain Underpants in Part 2, with a bit of Brainwashed and Crazy on top of it.
- In the Hack-O-Ween special, Melvin creates a machine that transforms the giant inflatable Hack-O-Ween balloons (Doctorca, Scorponion, Frobra) into living monsters.
- The Construction-fu robot in the interactive special.
- Bait-and-Switch: George and Harold become worried when it looks like Erica is going to turn into a "vimpire" like they'd portrayed her in their comic book. Turns out that Jessica is the one who becomes a "vimpire"; all the symptoms Erica was displaying were faked as part of her revenge scheme against them.
- Basilisk and Cockatrice: Season 3 introduces a "Barfsilisk"; a giant, mutated chicken from George and Harold's comics that can make anyone who stares at it's eyes barf rainbows.
- Being Evil Sucks: Laserlightmare, despite what it was created for, it always showed more interest in entertaining than actually containing the campers (rhyme completely intended). It even flat-out admitted to Melvin that being a living prison wasnt the job it wanted.
- Berserk Button:
- With Mr. Krupps Hair-Trigger Temper, it could be just about anything. But lets be real here; its George and Harold.
- In episode 6, we see that after his nervous breakdown, Mr. Fyde has developed an extremely low tolerance for noise. It only gets worse after he becomes the Monster of the Week.
- In episode 10, Theodore Murdsley hates hearing the name Ted Turdsley, due to it being the Embarrassing Nickname he received in his childhood after accidentally sitting in chocolate pudding.
- Julius Caesar from episode 21 doesnt like to be mocked, as shown after he reads the comic.
- Blonde, Brunette, Redhead: Harold, George, and Melvin respectively.
- Breaking Old Trends: Compared to previous season finales, Season 3 doesn't end on a Cliff Hanger Ending instead ending with the boys and Krupp enjoying themselves in a luxurious fashion.
- Bright Is Not Good: Laserlightmare and Sugamechanger, two monsters of the week from season 3 feature bright colors (Played literally in the former's case, as it is made of pure light).
- Broken Aesop: Unfortunately, it ends up happening a few times.
- "The Soggy Salvation of the Swirling Sweatnami" was meant to have a message that there's some good in everyone, but considering the events, it actually ended up doing just the opposite.
- In "The Blah Beat of the Blah Borelock", the message may have been meant to be that advertisement isn't always right, all until the end.
- The Bus Came Back: In the fourth book, Mr. Fyde has a nervous breakdown and quits his job to go live in a rest home. Episode 6 depicts his return to the school and ultimately becoming the Monster of the Week.
- In the Season 2 Finale, a majority of the villains/monsters that appeared in seasons 1 and 2 show up preparing to face off against George and Harold. Subverted when it's revealed that they're all just holograms meant to stall the boys from passing the test.
- For the Season 3 Finale, Sargent Boxers, Plungerina, and several other heroes and villains make an appearance for the camp talent show.
- As usual, Mr. Krupp and Melvin have their moments, but one could just chalk it up to karma.
- If Melvins not in this role in an episode, usually its Gooch or Other Sophie.
- Jerry Citizen. Pretty much nothing goes right for him, which does no favors for his already cripplingly low self-esteem.
- For the Halloween Special we get Creepy Rattlechains who suffers a lot of misfortune as the boys fight against Melvin and Krupp's ban on Halloween.
- Call-Back: With this being an adaptation of the book series, various plot elements take references from the books.
- In "The Terrifying Perilous Misfortune of the T.P. Mummy", Georges plan to get rid of their French teacher Ms. Yewh is to make a comic that embarrasses her so much, that she quits. Harold responds, Its worked before! Well, by accident. This is a reference to Book 3, where the boys comic about the school lunch ladies is the final straw for them, and they quit.
- Melvin's Future self being part cyborg who takes over the school is a reference to Book 6 with the plot point of how he initially planned to turn himself into a cyborg to gain more respect and credibility at Jerome Horwitz.
- In Season 2 "The Bombastic Blathering of Brainy Blabulous", the boys transfer to a Bizarro version of their school where the school is in better quality and the teachers actually care about the students, much like the Purple Potty universe in Book 8. Also, based on Book 12, the main antagonist is an alternate version of Meaner who is gifted with super intelligence.
- In The Movie, the driving conflict was Krupp threatening to place George and Harold in separate classes. In the season 2 finale, a similar conflict plays out where they discover at the last minute that they'll be going to separate summer camps. And in the season 3 premiere, it's revealed that Krupp was behind their separation.
- In Episode 3 Season 3, we get a cameo of Piqua's space program aka P.O.O.P.S.I.E. from Book 7.
- In the Epic Choice-O-Rama, Krupp is shown to pack sandwiches made of unconventional and junk-related ingredients. This is an ironic reference to Book 3 as Krupp was grossed out by the junk-filled sandwiches the boys prepared.
- Camping Episode: Exaggerated. Season 3 is an entire camping season.
- Canada, Eh?:
- Canon Foreigner:
- 'So good.'
- Of course, the iconic 'TRA-LA-LAAAAA!'
- Cliffhanger: Season 1 ends with this. And boy howdy, is it a doozy! Mr. Krupp gets fired, George and Harold get expelled, and Melvin, along with Superintendent Vil Endenemys (who is revealed to actually be his cyborg future self), take over the school.
- Not only that, but the alien cloak from Episode 8 is still out there. And when we last saw it, it took the form of Captain Underpants.
- And for the season 2 finale, George and Harold discover at the last minute that they'll actually be going to different summer camps. The two boys look sadly at each other as their buses drive them away while somber music plays in the background.
- Surprisingly averted in Season 3.
- Christmas Episode: "Captain Underpants: Mega Blissmas"
- Cold Open: Each episode opens with an introduction from George and Harold.
- Comic Books Are Real: Teachers and Students of Jerome Horwitz were always turned into the Monster of the Week as inspired by the two boys' comic books.Harold: This is a lot like the comic!
George: We're good that way!
- Continuity Nod: Season 3 makes more references to the previous seasons.
- For starters, the creepy ventriloquist dummy that resembles Krupp is shown in the first episode.
- Episode 2 references the Advancimals including George and Harold creating their own versions of the Advancimals to defeat the out of control animals.
- The "Krupp Brain Council" makes multiple appearances as well as introducing more members to the group.

- In Episode 6, George and Harold mention having met Mr. Krupp's mom. Jessica also displays her knowledge of sailing after her whale saving adventure in Season 1. Also also, the announcer of the regatta race advertises the T.P. Teepee.
- And in Episode 9, Krupp yells out his "I Am a Mountain" prep phrase from season 1.
- In the first episode of Season 4, we learn that Krupps high school was named after Charles Cotesworth Pinckney, who was mentioned all the way back in The Dreadful Debacle of DJ Drowsy Drawers.
- Cool Big Sister: Erica is one to the other kids in the "Krupp becomes a Corrupt Corporate Executive" timeline. She also has moments of this towards George and Harold throughout the series.
- Couch Gag: George and Harold switching the letters around on the Netflix Original card.
- Dark and Troubled Past: Parodied. Back sometime in the late 90's, Mr. Ree and his T.E.R.D.S. team attempted to flush a pile of envelopes down a gigantic toilet...only for the toilet to clog and overflow, resulting in the injury (and potential deaths) of almost everyone involved. In the present, Mr. Ree blames himself for not being able to stop it.
- Deadpan Snarker: Almost everyone in the show has their moments of this, but special mention goes to both Erica and Mr. Ree.
- Dissonant Serenity: Even after seeing Ms. Yewhs been turned into a toilet paper monster, Mr. Krupp still treats the situation casually and calmly. Even after she describes her plans to take all the TP and make everyone bow before her, he still remains unfazed.
- Dude, Not Funny!: No one likes the comic George and Harold use to mock Erica.
- George and Harold themselves have this reaction to Diddlysauruss idea for a prank; slipping laxatives to the entire school faculty, then locking all the bathroom doors so they couldnt get in to use the toilet.
- Dude, Where's My Respect?: This is what causes Smartsy Fartsy to turn on George and Harold in episode 12.
- Even Evil Has Standards: In the season 2 finale Melvin is horrifed when his future counterpart attempts to leave George and Harold behind in the nanobots husk.
- Everyone Has Standards: Yes, Krupp asked Melvin to find a way to keep the other kids afraid of Bo Hweemuth in the Claylossus episode, but even he thought Melvin turning Bo into an actual monster was going a bit too far. He only wanted to ruin Bos reputation, not make him destroy the city.Mr. Krupp: When I said make him a monster, I didnt mean make him a monster!
- Everything's Better with Rainbows: Subverted in season 3 with the Barfilisk, a giant chicken-like monster that causes anyone that stares into it's eyes to barf rainbows.
- Exit, Pursued by a Bear: Melvin and Melvin-Borg suffer this at the end of "The Harmful Horrors of the Harrowing Hiveschool."
- Expository Theme Tune: It even changes in the third season to fit the camp setting.
- Expy: The symbiotic cloak of alien origin that ultimately takes the form of Captain Underpants is a shout-out to Marvel's own Venom.
- Plungerina is an expy of Wolverine, even calling people "bub". Additionally, the villains whom she fights against, Cloggernaut and Clogneta, are based on X-Men villains Juggernaut and Magneto respectively.
- With his cloaking abilities and paintball-based hunting skills, Camoflush could very well be a kid-friendly version of Predator.
- Fake-Hair Drama: Mr. Krupp not only has a toupee, he also has a whole set of wigs.
- Franchise Zombie: Discussed In-Universe at the end of season 3. George and Harold wonder if the show is going to become one since the season ended on a high note and could easily be a series finale, then react positively to the idea of becoming this trope when they learn they're getting another season.
- Fun with Acronyms:
- In episode 5, T.E.R.D.S. stands for Toilet Eliminator of Really Dangerous Stuff. George and Harold seem to like this acronym.
- In episode 8, Judge J.O.R.T.S.s name stands for Justice Order Righteousness Tenacity Shorts.
- In episode 2 of season 2, the boys unite their friends to form the M.I.S.F.A.R.T.S. which stands for Mega Incredible Search Force Adventure Rescue Team Squad.
- For Season 3, Krupp frequently mentions the F.U.N.C. which stands for Federation of United National Camps.
- Future Me Scares Me: Melvin at first likes his future half-robot self, but eventually came to saw him as incompetent and created as many problems as he solved, opting to erase him from existence by changing the timeline.
- Gainax Ending: The ending of In Space! is one. The kids arrive back on Earth to discover it's become a Melvin-themed Shout-Out to the ending of Planet of the Apes (1968). George and Harold use the Time Toad to fix it (with the implication that the events of the entire previous season were undone), and then a future version of Captain Underpants (with versions of George and Harold attached to his biceps) shows up, claiming that the future's in danger. Roll credits.
- Gentle Giant: Bo Hweemuth. He towers over his classmates, and there are several rumors about him being a monster. But in reality, hes a shy, sweet, lonely, talented sculptor who wouldnt hurt a fly.
- Giant Foot of Stomping: A brainwashed Captain Underpants attempts to do this to George, Harold, and the Melvins in "The Taxing Trauma of the Treacherous Tattle Trials Part 2".

- Hard-Work Montage: Exploited in Episode 6 of Season 3 where the boys and their friends make a boat out of trash, complete with music.
- Hurricane of Puns: Captain Underpants has two of these, with bone puns in the Halloween Special and hand puns in Season 4's "Hangry Hypnosinger".
- Hypocritical Humor: In episode 6, Mr. Krupp, who is known for his Hair-Trigger Temper, calls Mr. Fyde a ticking time bomb.
- Idiosyncratic Episode Naming: Keeping in touch with the books, each of the episode's titles have alliterative naming, and the name of the villain that episode was centered on, as taken from George and Harold's comic books, usually to create the overly long structure Captain Underpants and the [alliterative noun here] of the [alliteratively-named villain here].
- I'll Never Tell You What I'm Telling You!: In the comic book of episode 12, Smartsy Fartsy tell Captain Underpants that he'll never find his fart bomb on top of the Eiffel Tower in Paris, France. The Captain takes an hour to figure it out.
- Improvised Clothes: In the books, Captain Underpants has no trouble finding a red-dotted fabric to make his cape out of (Usually the curtains in Krupp's office). In the series however Captain Underpants will just make do with any red material that happens to be nearby, including a red shirt, a tablecloth, or even a welcome mat.
- It Is Pronounced "Tro-PAY": Jessica tends to pronounce hair as haar, and applies similar pronunciations to homophones, such as "swear" becoming "swaar".
- Immediate Self-Contradiction: This exchange in "The Bizarre Bout of the Beastly Barfilisk":Melvin: Be my guest! Your stomach wont last 10 seconds.
Captain Underpants: Wrong! My super stomach can handle anything! Except spicy food, dairy, meat, fruit, nuts, grains, and vegetables. Oh! And liquid.
Melvin: What does that leave?
Captain Underpants: Marshmallows!
- Jerk Ass Ball: In "Captain Underpants and the Strange Strife of the Smelly Socktopus" Erica tricks George and Harold into getting suspended...for the sake of a prank. Unfortunately, it comes off as more cruel than funny since the suspension was played completely seriously, and (as Erica puts it) is is not fun.
- Journey to the Center of the Mind: In the second half of the Season 2 finale, George, Harold and the Melvins travel inside Captain Underpants' brain to save him from out of control nanobots that are corrupting his mind for their nefarious purposes.
- Kick the Dog: Melvin does it in the Claylossus episode. As if feeding the bad rumors about kind, lonely sculptor Bo wasn't enough, when George and Harold help show the other kids that he isn't that scary, he uses a machine to turn Bo into a monster against his will so that the school will still fear him. All so Mr. Krupp can give a letter of recommendation to the school of his choice.
- The Killjoy: Mr. Krupp is deliberately this in regards to school dances. While there are laws preventing him from outright cancelling them, there's no rule saying he can't make them as dull as possible, with the aid of the noise-hating music teacher Ms. Hurd as the DJ. That is until George and Harold decide to liven things up a little with their antics.
- Kraken and Leviathan: In The Monstrous Mayhem of the Massive Melviathan, the gang is pulled into a dimension where George and Harolds dreams become reality, therefor allowing Melvin to trick the two of them into bringing Harold's worst nightmare to life: the titular Melviathan, an aquatic behemoth with a head resembling Melvin's. Thing is, it actually bears more similarities to the kraken than the monster its named after.
- Lampshade Hanging: Tons. This show seems to love this trope.
- Lame Rhyme Dodge: In "Preposterous Pulverizing of the Pestering Poopacabra" When Melvin and Melvin-Borg force Mr. Krupp to carry a huge heavy box into the school, then hammers a huge panel on the hallway wall.Melvin-Borg: Manual labor suits you vice Principal Krupp. By that, I mean you have opposable thumbs and a beating heart!
Krupp: (growls) I swear, one day I will destroy you.
Melvin-Borg: WHAT WAS THAT?!
Krupp: Um, I said, uh... "Hi, there! Fun day. Why fill my toy shoe?
Melvin-Borg: Did you just replace the words you just said that you didn't want me to hear with random gibberish words that rhyme with those words?
Krupp: No! No... Snow. Snow! (chuckles nervously)
- Life Imitates Art: In-Universe; almost every Monster of the Week is based on a villain from George and Harold's comics, much to their enjoyment.
- Logo Joke: George and Harold draw the DreamWorks logo with Captain Underpants on it. He flies away, but his underwear is caught.
- Made of Explodium: In the Cold Opening of "The Vexing Villainy of the Vile Vimpire", George and Harold create a comic where everything around Captain Underpants explodes.
- Meaningful Name: Not only does Superintendent Vil Endenemys's name sound like "villain and enemies", it's also a Significant Anagram; rearrange the letters and they spell "Melvin Sneedly".
- Medium Blending: Stop-motion animation is often used, mainly "Captain Underpants and the Costly Conundrum of the Calamitous Claylossus".
- Usually, each O-Rama would rely on this trope.
- The series also uses puppets of various types.
- Monster of the Week: Runs on this formula, with various villains based on George and Harold's comics coming to life.
- Mood Whiplash: The ending of the Season 1 finale. What starts out as a very heartwarming moment as the boys give Mr. Krupp his rule book back, causing him to have what could be the start of a HeelFace Turn as he seriously considers not expelling them... takes a hard left turn as its revealed that Melvin went behind George and Harolds backs, still gets Mr. Krupp fired (and the boys expelled on top of it), and takes over the school with his cyborg future self, ending the season on a Cliffhanger.
- The same thing happens in the Season 2 finale. The boys finally succeed in defeating Melvinborg and are able to go to summer camp like they always wanted! There's just one problem. They're actually going to separate summer camps. The finale ends with the two boys sitting in separate buses while sad music plays in the background, leaving them along with the audience to wonder how they're going to resolve this problem.
- Most Writers Are Male: In-Universe, Erica complains that George and Harold's comics need more female characters, preferably "strong" ones. Finding the task too daunting, the two vent their frustrations by writing a Captain Underpants story in which an evil vampire (based on Erica) sucks the fun out of everything. Understandably, not only does Erica hate it, so does the rest of the school.
- My God, What Have I Done?: Mr. Krupp says it nearly word for word after making Laserlightmare destroy the camp.
- Krupp: Ah! What have I done?! How can things get any worse?! (Escaped rhinosaurus runs into him)
- Named by the Adaptation: Mr. Krupp's mother had no name in the books, while here her name is Bernice.note
- Nanomachines: Season 2 episode 12 and 13 has them play a major part in the story. The first of which where Melvinborg injects his child self with them in order for the latter to win the Tattle Trials, which eventually cause him to grow into a gigantic version of himself after the machines are turned all the way up. In the next episode, the nanobots take over the doom dome, and eventually cause the same to happen with Captain Underpants, and brainwashing him, as the icing on the cake.
- Nice, Mean, and In-Between: A reccuring theme between the students of Jerome Hortwitz, particularly the canon foreigners.
- The three main girls introduced the series (excluding the Sophies) tend to fall into this, with Dressy, who's a kind, cheerful, and polite being the nice one, and Jessica as the mean one, being entitled, self-absorbed, and egocentric. Erica stays in-between, who, while good-hearted, is considerably more assertive and snarky than Dressy.
- Jessica's girl posse also plays out like this. Other Sophie being the submissive doormat to Jessica, who recycles her role as the mean. Leaving Sophie One, the favorited Sophie, mediating between the two.
- The male kids most primarily focused on in the series aside from George and Harold also come out like this.
- Nice: Bo Hweemuth, a diffident and kind-hearted Misunderstood Loner with a Heart of Gold with hidden talents.
- Mean: Melvin Sneedly a narcissistic Insufferable Genius and well-known antagonist.
- In-Between: Gooch Yamaguchi a sweet, but inept and clumsy Asian Airhead.
- No Inside Voice: No matter the situation, Captain Underpants always shouts when he talks.
- No Sense of Humor: Subverted with Melvin. Unlike in the movie, he does have somewhat of a sense of humor its just that its incredibly dull. According to him, videos of rotting food are cant miss comedy.
- Nothing Is the Same Anymore: Subverted. Season 1's finale ends with George, Harold, and Mr. Krupp kicked out of Jerome Horwitz Elementary, seemingly making season 2 take place outside of the school...And when season 2 starts, George and Harold's expulsion is reverted as their expulsion was deemed unlawful and Mr. Krupp quickly got rehired, albeit as vice principal.
- Overly Long Gag: Several of the jokes and scenes in an episode end up running longer than preferred.
- Overly Long Title: Used once an episode.
- Paint Ball Episode: Season 3 The Cunning Combat of the Covert Camoflush revolves Mr. Rees younger brother Major Messy coming to camp for a free paintball game, and eventually becoming the Monster of the Week and turning the campers into his rebellious, rule-hating minions.
- Parental Sexuality Squick: In the Halloween special, Harold spots the implications of Mr. Meaner becoming his mom's artistic muse and promptly goes into a Heroic BSoD.
- Planet of Steves: Jessica calls her two best friends, the Sophies.
- Plot Hole: In-Universe; To explain why he hates rich people so much, Mr. Krupp tells the kids a story about how he was a lonely orphan whose hopes for adoption were raised and then dashed by a rich person. George and Harold quickly point out that they've met Krupp's mom before.
- Punny Name: As usual, especially among the teachers. Also, the new characters teaching at Jerome Horwitz, such as Ms. Yewh being a play on the french way to say mister, "Monsieur" (as well as miss you), Bo Hweemuth being a play on the word "behemoth", Señor Citizen being a pun on "senior citizen", Mr. Ree being a pun on "mystery" (with his full name being a pun on 'toiletry,) Miss Anthrope's name being a pun on the term "misanthrope," Lee Dingman being a pun on leading man and [[spoiler:Superintendent Vil Endenemys being a pun on Villain and Enemies.
- Race Lift:
- Jessica Gordon was a minor character mentioned in Book 6, who was drawn as white and more closely resembled Harolds sister Heidi. Here, she's black and looks completely different.
- Just like in the movie, Miss Anthrope and Mr. Fyde, who were both drawn as white in the books, are also now black.
- Rapid Hair Growth:
- Jessicas haar gets zapped by one of Melvins inventions near the end of the first episode, making her already ridiculously huge hairdo even bigger.
- In episode 12, George and Harolds impending expulsion actually causes Mr. Krupps hair to start growing back. He winds up with a full head of hair in a matter of days.
- Reality Ensues:
- At the end of Episode 9, George and Harold are successful in getting themselves suspended on purpose. Unfortunately for them, their parents aren't as thrilled and they punish the boys by having them mow the lawn with their hands. As Erica tells them, suspension is terrible.
- In Episode 5 of Season 2, the boys travel back in time to pick up a dinosaur for extra credit thinking that the task will be easy. It takes less than a minute for them to realize that dinosaurs are dangerous creatures who will not hesitate to eat you.
- In the Halloween Special, Erica explains that the reason that most adults don't like celebrating Halloween is because of all the work they have to do. From buying candy, setting up decorations, carving pumpkins, making/buying costumes, giving away free candy and having to deal with property damages due to unknown pranksters. For kids, Halloween is one of the greatest days in the year. For adults, it's an unnecessarily busy day for them with no proper payoff.
- When George and Harold get expelled by Future Melvin, it's repelled almost immediately by the school superintendent because many of the rules the boys broke were rules Krupp added himself, which he didn't have the authority to do.
- Recycled IN SPACE!: Season 4, or as its known by its official title on Netflix, The Epic Tales of Captain Underpants in Space.
- Reused Character Design: Played for Laughs and exploited in each season.
- In season 1 episode 3, the boys travel back to an Ancient Egyptian classroom and discover that the students look exactly like their friends only in Egyptian attire. Harold comments on the similarities while George states that the show doesn't have the budget for new character designs.

- Scooby-Dooby Doors: Used in the first episode when Mr. Meaner chases George and Harold around the school.
- Screams Like a Little Girl: George has a habit of doing this every now and then.
- Screw the Rules, I Make Them!: Mr. Krupp would arbitrarily write rules in the school rule book just so he can get George and Harold in trouble.
- Self-Deprecating Humor: There are moments where the show acknowledges how it's cheap humor and average writing isn't something to be admired.
Erica: "To be fair, with all the puns, toilet humor, and lazy writing, they had it coming."
- In the season 3 finale, George states that the show isn't going to win any awards with fart jokes.
- In the Hack-O-Ween Special, while discussing how Advancimals ended up cancelled, Erica brings up several reasons that feel painfully similar to the Captain Underpants cartoon and the books.
- Series Fauxnale: The season 3 finale ends with George and Harold talking about how the season ended happily and wondering if the show is going to become a Franchise Zombie. A plane then flies by with a banner proclaiming that more episodes will be coming soon, which they respond happily to.
- Shout-Out: This show is FULL of them! It's so full that they had to make a whole page for it!
- The Show of the Books: The show has been styled like the books.
- Sickly Green Glow: After the nanobots made their way into Captain Underpants' brain, his eyes obtained a green glow.
- Sleep Cute: Pretty much all the kids in the series have this custom.
- Smart People Wear Glasses: Invoked and lampshaded. The students and faculty of Herome Jorwitz, a Bizarro Universe of Jerome Horwitz, all wear glasses and Harold proclaims that all of them must be smart because of this trope.
- Smell Phone: In the first episode, when the Monster of the Week Flabby Flabulous farts on our heroes, the Lemony Narrator tells the viewers to "turn down the smell on their TVs."
- Sour Outside, Sad Inside: A handful of episodes, particularly the Halloween special heavily hint Melvin to be this, as a flashback reveals that his hatred of the titular holiday originates from him never being invited to go trick-or-treating with them.
- Story Branching: The "Captain Underpants Epic Choice-O-Rama" allows the viewer to change the direction of the storyline by providing them choices at certain parts of the episode.
- Stealth Hi/Bye: Erica does this quite a few times. George and Harold even compare her to Batman in one episode.
- Strictly Formula: Most episodes go like this: George and Harold have an encounter with a teacher, they get sent to the principal's office, they make a comic about said teacher, the teacher somehow turns into the Monster of the Week, Krupp turns into Captain Underpants, the fight scene is presented in Flip-O-Rama, the teacher turns back to normal, Captain Underpants turns back into Krupp and gets distracted before he can realize what's happened, the episode ends.
- Take That!:
Announcer: Advancimals! This show was destined to fail!
- Subverted. While the majority of the kids in the show (including George and Harold) like Advancimals, the kids also know that the show was created to sell merchandise and suffers from lackluster writing.
Harold: I just hope that we live long enough to see it get a reboot.
- In the interactive episode, Harold and George lament the cancellation of their favorite show Gorilla Lawyer, leading to this exchange:
George: ...So, in like a year?
- Tears of Joy: Melvin sheds these upon George, Harold, and the other students taking a stand aganist the Ted Turdsley cycle.
- Tempting Fate: In the TP Mummy episode:Narrator: This is Mr. Ree, the school janitor. He's a dedicated employee and definitely doesn't have a secret past...Ooh, I've said too much.
- Throughout Season 2, the Narrator lampshades how the boys always saying that things are going right for them and how nothing can go wrong is always just asking for fate to prove them wrong.
- Melvinborg does it twice, regarding his nanobots finding a new host, in the Season 2 finale. The boys shoot him a Death Glare the second time he does it.
- Time Machine: Melvin uses a "Time Toad", on which can be powered using peanut butter. The boys would end up using his machine throughout the series with varying results.
- Toilet Humour: "The Terrifying Perilous Misfortune of the T.P. Mummy", in spades.
- Toilet Paper Prank: In "The Terrifying Perilous Misfortune of the T.P. Mummy", George and Harold cross the line by putting toilet paper everywhere. Mr. Krupp had them banned from the toilet paper store after that incident.
- Took a Level in Jerkass: Jessica and the student body during the Butt-erfly invasion. Under Jessica's orders, they willingly throw George, Harold and Melvin out of the cafeteria to allow them to be eaten after they learn that they were responsible for the butt-erflies' creation. None of them face any repercussions afterwards.
- Took a Level in Kindness: Most of the Jerome Horwitz Elementary staff, if you can believe it. Yes, they still have their Jerkass moments (especially if theyre the Monster of the Week for that episode), and of course have low tolerance for George and Harolds shenanigans, but they are nowhere NEAR as cruel as they were in the books. They're honestly more hilariously incompetent than all-out Sadist Teachers.
- Trademark Favorite Food: Episode 6 shows us that Krupp has a rather... bizarre one; guacamole. Its to the point that he can't help himself if its placed in front of him... even if its clearly spoiled.
- Trash the Set: In Episode 11 of season 3, Krupp programs Melvin's security system, Laser Lightmare, to ruin everyone's fun which results in the complete annihilation of the summer camp.
- Unwitting Instigator of Doom: Erica at the end of Season 1. She is the one who suggests to George and Harold that they go to Superintendent Vil Endenemys to try to get Mr. Krupp fired before he can expel them, not knowing that Vil Endenemys is actually Melvin Sneedlys future self, who not only fires Krupp, but expels George and Harold and takes over the school with Melvin.
- Verbal Tic:
- Mr Meaner's variations on 'Yep yep yep yep yep'.
- Dressy's habit of singing some of her dialogue might count.
- Villainous Crush: Melvin has one on Erica. But given his reputation, it's unlikely that she reciprocates it.
- Vomit Chain Reaction: "The Bizarre Bout of the Beastly Barfilisk" ends with Mr. Krupp and the kids all spewing arches of colors one by one due to the effect the titular beast's rainbow barf powers.
- Vomit Discretion Shot:
- Mr. Krupp vomited behind his desk after eating George and Harold's guacamole for their prank.
- Another episode has George and Harold vomiting in their wigs.
- Melvin hurls under the screen after getting a whiff of skunk-sprayed George and Harold.
- At the end of the Hack-O-Ween special, Melvin eats a piece of candy and he hurls under the screen.
- Vomit Indiscretion Shot: In episode 2, Ms. Hurd has an Imagine Spot of a werewolf throwing up.
- Wham Episode: The Season 1 finale, specifically the ending. George and Harold change their minds about giving Mr. Krupps rule book to the Superintendent to get him fired, so they enter Krupps office to give it back, but this marks office visit 500, so theyre gonna be expelled. Mr. Krupp is naturally elated... that is, until the boys give him back his rule book, apologize, and are willing to accept their fate. Mr. Krupp is so emotionally torn by this, that he has a minor HeelFace Turn and is about to change his mind about expelling them. So everythings okay now, right? WRONG! Turns out, Melvin, knowing that George and Harold wouldnt have the hearts to actually go through with it, went behind their backs, switched the rule book with his mothers cookbook, and gave the real rule book to the Superintendent, so Krupp still gets fired. And if that werent enough, the Superintendent goes around and expels George and Harold, too! Why would he do this? Because Superintendent Vil Endenemys is none other than Melvin Sneedly, specifically his future self. Oh, and hes a Cyborg. Mr. Krupp, George, and Harold are then booted out of the school, and can only watch in horror as Melvin and Future Cyborg!Melvin take over.
- Wham Line: The Season 2 finale ends with one.Harold: Huh? Wait, why are there two buses?
(The boys check over their camp paperwork; Georges says Camp Lake Summer Camp and Harolds says Lake Summer Camp Camp)
George and Harold: Two different camps!
- Wham Shot: In the Season 1 finale, after he fires Krupp and expels George and Harold, Superintendent Vil Endenemys decides to humor the boys a bit by playing to their love of rearranging letters on signs, and asks them to rearrange his name. After a few tries, they finally rearrange the letters to reveal his true name to not only them, but the audience; MELVIN SNEEDLY. Even Melvin himself was shocked by this revelation!
- With Friends Like These...: Jessica Gordon treats Other Sophie more like a slave than a friend. In a flashback in Season 3, we see that while Jessica was the only one to show up at Other Sophies birthday party, she almost immediately leaves, and steals all of Other Sophies birthday presents while shes at it!
- You Have Outlived Your Usefulness: Playfully parodied in "The Frantic Fury of the Fearsome Furculees". George and Harold recruited their friends (Erica, Bo, Gooch, Dressy, Jessica and the Sophies) based on a specific talent that they contribute to the search for Mr. Krupp. Once they've displayed their talent to help them, they immediately leave the search to have fun at the resort.
