An American cartoonist and writer, Theodor Seuss Geisel (March 2, 1904 September 24, 1991), more commonly known as Dr. Seuss (pronounced "soyss" like "voice," although he later accepted the far more common "sooss" like "juice"), was famous for his 65 children's books.
Seuss was the son of a family of brewers, which made the Prohibition era a tough period to deal with. He went to Dartmouth College where he became the editor of the campus humor magazine, Jacko until he was caught in a drunken incident that made the Dean expel him from the editorship. An indifferent student, Seuss still went to Oxford when he made a pretence of getting a scholarship there, which forced his father to send him there on his own money to save face. There, Seuss struggled with his studies until he met his future wife, Helen, who noticed his idle fanciful drawing in his notes looked good enough to be professional.
Once they married and returned to the US, Seuss struggled to work professionally as a cartoonist and illustrator until he finally landed a steady gig as a cartoonist at the humor magazine, Judge. At the magazine, Seuss often did Product Placement in his cartoons and mentioned the insecticide brand, Flit, by chance. That caught the attention of a wife of an executive at Flit and Seuss was commissioned to draw a long campaign of advertisements for Flit ("Quick Henry, the Flit!") that became a sensation for their humor, and established the trope of the Cartoon Bug-Sprayer. That got him an exclusive contract that would last 17 years and would get his family through The Great Depression with relatively little hardship, which made children's literature one of the few other fields he could work in.
Most of his work liberally uses rhyming schemes, illogical logic, fantastical buildings, nonsensical vocabulary, and very pretty illustrations. This, at the time, was fairly radical and the epitome of avant-garde, though not by today's standards. Seuss was a lifelong inhabitant of Springfield, Massachusetts, and drew inspiration from his surroundings; for instance, his first published children's work, And to Think That I Saw It on Mulberry Street, took place on a real life street. (The book's events occur on the intersection of Mulberry and Bliss Streets, which both exist. However, the real-world versions never cross.).
Although breaking into children's lit was a struggle at first, Dr. Seuss' infectious charm and imagination would have him hailed as the great 20th Century master of the form. The fact that he intentionally discredited the insipid Dick and Jane primer series along the way while his energetically imaginative work set the standard for modern kids' book that kids wanted to read is a testament of that talent. In fact, that success, beginning with his signature character, The Cat in the Hat, would lead to Seuss having a secondary career as co-founder and editor of Random House's Beginner Books imprint which published the work of numerous talents such as Stan and Jan Berenstain of The Berenstain Bears series. However, that proved a bother to him, considering that the books Seuss personally wrote under that imprint were burdened with limits he hated like strict vocabulary lists of typically less than 300 words, even though he rose to the challenge and created his most bestselling book, Green Eggs and Ham, which had a vocabulary list of only 50. Eventually, he took full control of the company and broke free to create books with all the words he wanted like There's a Wocket in My Pocket!.
Besides his children's work, Seuss was a political cartoonist, most notably for the now-defunct magazine PM. He was a committed New Dealer and supporter of Franklin D. Roosevelt, and liberal causes generally. On the less savory side, while he opposed anti-semitism and segregation, Seuss is also known for being quite racist towards Japanese in his WWII-era political cartoons (here's◊ an example). He later realized such work was inappropriate and felt horrible about it. He was against Jim Crow, even basing one book on getting over small differences (also dedicating Horton Hears a Who! to a Japanese friend). He would probably enjoy that hand-drawn, Animesque spoof in the 2008 Horton movie quite a lot! Still, some of his later work did nonetheless reflect lingering prejudices in western society at the time, and that combined with the Values Dissonance of his early work eventually led to his estate pulling six particularly poorly-aged booksnote from circulation in 2021.
Eventually, Seuss decided he had to do more for the war effort, and got an officer's commission with the Army. He was assigned to the Signal Corps under the command of Frank Capra to produce propaganda and instructional films for the military. His best known work in this capacity was with the Private Snafu cartoon series, working with luminaries like Chuck Jones. With that series, Seuss would be responsible for military instructional cartoons that enjoyed a content freedom undreamed of in the civilian market, with his writing talent most evident in Rumors.
Much of his work has been movie-fied, whether by animation or live-action. The only movie he himself made was The 5000 Fingers of Dr. T, a bizarre film that proved a flop. He did collaborate with various directors (most famously his close friend Chuck Jones) in adapting his stories for television, but again, those were TV specials, and not feature-length. When he passed away on September 24, 1991 due to oral cancer, the rights to all his stories and characters went to his widow, Audrey, and no adaptations could be made without her permission. After the dismal 2003 adaptation of The Cat in the Hat soured her for the casting of Mike Myers (whom she was strongly against) and the adult jokes that clashed with the family friendly nature of the books, she vowed never to produce any future live-action adaptations of her husband's works for the rest of her life. Audrey herself died on December 19, 2018, at the age of 97, shortly after Warner Bros.. obtained exclusive adaptation rights to all of Dr. Seuss's work.
There's also Seuss Landing, a portion of Universal's Islands of Adventure, which features rides, costumed characters and other attractions based on the books.

Dr. Seuss and his books provide examples of:
- Adaptational Nice Guy: His less-than-admirable characters tend to get a bit more depth when translated to screen. The Grinch, the Once-Ler and the grouchy companion from Green Eggs and Ham go from being one-dimensional antagonists who eventually turn good into guys who always had a good side that was buried under years of misery. These adaptations also tend to fill the void with villainous characters who are really unlikable.
- Adaptation Expansion: All of the feature films and most of the TV adaptations tend to add more material to the plot to keep from running too short.
- Aerith and Bob: In The 500 Hats of Bartholomew Cubbins there is Bartholomew Cubbins, King Derwin, Sir Snipps, Alaric and the Grand Duke Wilfred.
- An Aesop: Most books that aren't simple rhyming books contain one (notably The Lorax, The Butter Battle Book, Green Eggs and Ham, Oh, The Places You'll Go!, and Did I Ever Tell You How Lucky You Are?)
- Animated Adaptation: There have been numerous animated works based on Seuss's books, including three feature films.
- Art Evolution: In illustrations of the earliest books, characters were not always originally depicted with "u" shaped pupils. In And to Think that I Saw It on Mulberry Street, nearly every character, except for a few non-humans, were, in fact, shown with Black Bead Eyes. They had sclerae in The 500 Hats of Bartholomew Cubbins but pupils were depicted round and normal. While certain characters had the u-shaped pupils early on, others still did not. This, before finally settling on all characters depicted as such, as would be the later known style.
- Barbie Doll Anatomy: The title characters of The Seven Lady Godivas are naked, but none of them are drawn with visible nipples or genitals.
- "Before" and "After" Pictures: One of his wartime cartoons had an Uncle Sam Eagle in a Charles Atlas-like parody ad with "Before" and "After" pics:"I was weak and run-down. I had circles under my eyes. My tail drooped. I had a foul case of Appeasement.........then I learned about 'GUTS' that amazing remedy For all Mankind's WoesNow I am taking it daily and today I feel strong enough to punch Mister Hitler right in the snoot!"
- Beware the Nice Ones: Surprisingly, involving Horton in a long lost story, Horton And the Kwuggerbug, where a Kwuggerbug takes advantage of Horton's kindness, asking Horton to give him a lift to a beezelnut tree, with the promise of splitting half the nuts with him. The journey proves to be incredibly dangerous, and Horton is tempted to go back, but the Kwuggerbug reminds him that a deal's a deal and to keep going. When they finally get there, the Kwuggerbug ends up stiffing Horton by only giving him the shells, taking the good parts for himself. Enraged, Horton sneezes and blows the bug so far away, that he is never able to return to the beezelnut tree again.
- Bittersweet Ending: A number of books, but The Sneetches is a prominent example. In the end, McBean successfully cons the sneetches out of all their money with his Star Machine gambit, leaving them penniless, but the experience teaches them how stupid and pointless racial discrimination is and they learn to live as equals from that point on.
- Bowdlerise: In The Lorax, the Lorax's line, "I hear things are just as bad up in Lake Erie," was removed from the book in 1985 after two research associates from the Ohio Sea Grant Program wrote to Seuss about the clean-up of Lake Erie. However, the same line is still kept in the 1972 TV Animated Adaptation (it is spoken by one of the Humming Fish), even in the VHS and DVD releases.
- Canon Foreigner: All movies and most TV adaptations of his books added characters that weren't in the source material.
- Cartoon Bug-Sprayer: An ad campaign drawn by Dr. Seuss for Flit brand insecticide featured people facing down improbable creatures with this style of sprayer, with one character always exclaiming the slogan, "Quick, Henry, the Flit!" The ads were wildly successful and doubtless contributed to the Flit-style bug sprayer persisting as a stock cartoon image long after the technology fell out of use in real life.
- Casts No Shadow: Harry Haddow in Did I Ever Tell You How Lucky You Are?He thinks that, perhaps, something's wrong with his Gizz,
and I think that, by golly, there probably is.
- Catchphrase: Horton the Elephant has two: "A person is a person, no matter how small." (Horton Hears A Who) and "I meant what I said and I said what I meant. An elephant's faithful 100%." (Horton Hatches the Egg).
- Cerebus Syndrome: Sometime around the late '60s/early '70s, Seuss began writing darker stories like I Had Trouble in Getting to Solla Sollew and, eventually, The Lorax, which featured more abundantly heavy themes than his previous books and not always the happiest of endings. Not coincidentally, this began after his first wife committed suicide.
- Characterisation Click Moment: In the short story "The Grinch and the Hoobub", the Grinch both looks and acts somewhat differently, posing more as a smooth-talking Lovable Rogue. It is his second appearance, How the Grinch Stole Christmas!, that solidifies the Grinch with his iconic personality as a curmudgeonly Card-Carrying Villain with a Hidden Heart of Gold, though with his original trickster side maintained as a secondary trait.
- Conjoined Twins: The Brothers Ba-zoo in Did I Ever Tell You How Lucky You Are? are conjoined by their hair.
- Control Freak: Was extremely particular about every detail of his books, from the font size to the spacing of the text from the illustrations to, above all, the colors. He was known to pitch a fit if the Random House printers weren't able to exactly duplicate even one of the colors he put in his drawings.
- Cool Old Guy: The fellow who the narrator of Did I Ever Tell You How Lucky You Are? meets in the Desert of Drize, who, well, tells him how lucky he is.
- This concept appeared earlier in Dr. Seuss's work, as well.
- Cool and Unusual Punishment: Droon is forced to eat nothing but Nizzards at the end of The King's Stilts.
- Cosmic Horror Story: Bartholomew and the Oobleck, if you think about it. A greedy person bored with ordinary life orders his magicians to summon new weather, which results in the arrival of an ambiguous, borderline-unstoppable phenomenon of potentially apocalyptic proportions. The only thing holding it back is the presence of An Aesop about saying sorry, and even then the closing lines about the current weather being the only things that ever should be is subtly sinister.
- Creator Cameo: In There's a Wocket in My Pocket!, the Bofa on the Sofa (who the narrator wishes wasn't there) looks very Ted Geisel-ish.
- Creator Provincialism: Seuss lived in Springfield, Massachusetts for the entirety of his youth and drew inspiration from his surroundings. Springfield is mentioned in several of his works (most notably Mulberry Street) and some of his illustrations are surreal versions of real places in town. Today the Springfield Museums have, in a courtyard behind the city's central library building, an outdoor shrine to him that includes statues of him and various characters, as well as a giant book statue containing the entire text of Oh, The Places You'll Go. There is also a Seuss museum, which is largely a childrens museum but has sections in the upper floors with his papers and other work... though not his World War Two cartoons.
- Darker and Edgier:
- The Lorax is this compared to the other books. It teaches about the consequences of not acknowledging natural resources until they are gone.
- Even more so, The Butter Battle Book is a parable about the nuclear arms race between the US and the USSR, represented by two tribes living on opposite sides of a wall analogous to the Berlin Wall, concluding with a Bolivian Army Ending as the two sides are about to drop their bombs.
- His work as a political cartoonist during World War Two was this, dealing with real world issues about supporting the Soviet Union against the Nazis and supporting Japanese internment. Seuss would later regret the latter.
- "The Midnight Paintings" was a collection of paintings Seuss made in private. These paintings touch more on his cynical side and had a very different art style compared to his books. Seuss requested for these to never get released to the public until after his death. Solar Sands made a video giving more exposure on his "Midnight Paintings" series.
- Dark Is Not Evil / Light Is Not Good: I Can Read With My Eyes Shut gives us Jake the Pillow Snake and Foo-Foo the Snoo. One is a snake and the other is named Foo-Foo. Guess which one looks friendly and which one looks menacing.
- Sam, who keeps trying to get his friend to try green eggs and ham after being rejected countless times.
- Horton is always faithful, one hundred percent.
- The Lorax gets a speech that illustrates this well in his book's 1970's Animated Adaptation.I speak for the trees! Let 'em grow, let 'em grow!
But nobody listens too much, don't you know?
I speak for the trees, and I'll yell and I'll shout
For the fine things on Earth that are on their way out!
They say I'm old-fashioned, and live in the past,
But sometimes I think progress is progressing too fast!
They say I'm a fool to oppose things like these,
But I'm going to continue to speak for the trees!
- This Trope is portrayed negatively in "The Zax," from The Sneetches and Other Stories; both Zax are too stubborn to step aside and let the other pass, and simply stand there for years, refusing to budge, until an entire city is built around them!
- Didn't Think This Through: From Did I Ever Tell You How Lucky You Are?, there's poor Herbie Hart, who has taken his throm-dib-u-lator apart, and is trying to put it together.
- Downer Ending: The Lorax ends with the forest gone, the animals gone, and the Lorax gone. Only the Once-ler remains, who regrets his actions. However, there is one ray of hope: UNLESS. If the boy can regrow the forest and protect it, maybe the Lorax will come back.
- Early Installment Weirdness: Some of his earliest children's books, like The 500 Hats of Bartholomew Cubbins and The King's Stilts, were written in prose rather than in rhyme. (This was also true of the sequel to the former, Bartholomew and the Oobleck, although it was grandfathered in from its predecessor, since by the time the book was written, he had consistently switched to rhyme).
- Evil Chancellor: Droon of The King's Stilts. Well, more of a Jerkass Chancellor anyway.
- Exactly What It Says on the Tin: The Pants-Eating Plants from Did I Ever Tell You How Lucky You Are?
- Expansion Pack Past: He had no compunctions about bending the truth of his own life to make for a better story. Among the biggest is that his famous pseudonym originated to get around being banned from contributing to Dartmouth's humor magazine for drinking liquor during Prohibition, when in fact it appears on several of his cartoons made before that incident, and afterwards he simply left them anonymous until the board figured it out and forbade any more entries without a credited writer. Let's just say he didn't have to stretch very far to write And to Think That I Saw It on Mulberry Street.
- Extreme Omnivore: Again, the Pants-Eating Plants.
- Failed Future Forecast: The animated version of The Butter Battle Book, a Cold War allegory with a Berlin Wall expy, aired four days after the real Berlin Wall fell.
- Fantastic Flora: Much of his visual work incorporates bizarre-looking trees and shrubs, many of them inspired by Real Life exotic botanical species grown at the San Diego Zoo. Seuss spent much of his time there after settling in La Jolla.
- Fantastic Racism: The Sneetches is a thinly disguised allegory on racism (or classism). It describes a conflict between two subgroups of the titular Sneetches, a race of bird-like humanoids. One group has stars on their bellies, and thinks themselves superior because of it, while the other group doesn't. The Aesop comes after a huckster with the unlikely name of "Sylvester McMonkey McBean" convinces those without stars to pay him to have stars added to their bodies. Then it's no longer so special, since everyone has stars, but McBean has a machine to remove them as well, for a modest consideration. The two groups proceed to repeatedly alter who has stars and who doesn't, along with which of the two conditions are more desirable. By the time McBean packs up his operation and leaves, they don't remember who had stars to begin with and who didn't, and thus abandon their prejudices as worthless.
- The Film of the Book: How the Grinch Stole Christmas (twice), The Cat In The Hat, Horton Hears A Who!, The Lorax
- Four-Temperament Ensemble: The (arguably) four best-known of his characters: the Cat in the Hat (sanguine), the Grinch (choleric), Horton (phlegmatic), and the Lorax (melancholic).
- Get Out!:
"But it's MINE!" screamed the bird, when she heard the egg crack.
- This is shouted by Mayzie in "Horton Hatches the Egg" when, after allowing Horton to sit on her egg because she's too lazy for that responsibility, the egg of his starts hatching:
(The work was all done. Now she wanted it back.)
"It's MY egg!" she sputtered. "You stole it from me!
Get off of my nest and get out of my tree!"
- Marvin K. Mooney, Will You Please Go Now! is an entire story telling the main character this.
- Grand Finale: Oh, the Place You'll Go!. When Dr. Seuss submitted the manuscript, everyone involved realized it would be his last book.
- Happy Birthday to You!: The Mandolin plays this briefly at the end of The Hoober-Bloob Highway.
- Hard Work Hardly Works: The old man in Did I Ever Tell You how Lucky You Are tells the kid about a lot of folks who work hard at crummy jobs. Ali Sard has to mow "quick-growing grass" in his stingy uncle's backyard, and paint flagpoles on Sundays to get by. Mr. Potter is an t-crosser-i-dotter who dots i's and crosses t's at an I and T factory. Then there's Professor DeBreeze who has spent 32 years trying to teach Irish ducks how to speak Jivanese. The worst example is probably the Hauch-Hauchers in Hauch-Hauch. One was told to watch a bee, but didn't do well, so another was told to watch him. Then he didn't do so well, so another Haucher had to watch him, and so on, until all of them were watching each other.
- History Repeats: Very subtly done in the title tale of Yertle the Turtle and Other Stories. After Yertle is dethroned and sent tumbling down into the swamp mud, the turtles that had previously made up his throne are swimming happily in the pond, with their eyes closed... Except for Mack (whom the other turtles are swimming towards), who is sitting on Yertle's old "throne" and looking upwards towards the sky. Considering Seuss's background as a political cartoonist (and that he admitted the story is an allegory for Hitler), the implication isn't difficult to spot...
- Honorable Elephant: Horton is always faithful, one hundred percent.
- Hotter and Sexier: The Seven Lady Godivas, which is pretty much a Dr. Seuss Ecchi book.
- Human Mail: One of the suggested methods of departure made to Marvin K. Mooney.
- Humans Are Cthulhu: The protagonist of "What was I Scared of?" from The Sneetches and Other Stories doesn't look human, but it's the same idea. He keeps running into a ghostly pair of Pale Green Pants which he is terrified of... Until the end, when he discovers that the pants are even more terrified of him. (Unlike most examples of this Trope, the story has a happy ending, with the two of them coming to terms with the fears and becoming friends.)
- I Gave My Word: See Honorable Elephant above.
- Ignored Epiphany: The Once-ler does this twice in the 1972 Animated Adaptation of The Lorax. Once when the Bar-ba-Loots were sent away, and again when the Swomee Swans and Humming Fish leave. The latter instance segues into his rant from the climax of the book.
- "Just So" Story: The bulk of The Seven Lady Godivas is taken up with the sisters learning "horse truths." These consist of humorous, overly literal origin stories for common horse-related idioms.
- Karma Houdini: The makers of the Horton Hears A Who film note in the commentary that he "wasn't in the comeuppance business." In fact, with the exception of Yertle the Turtle, the unwelcome guests in Thidwick the Big-Hearted Moose and the Kwuggerbug in Horton and the Kwuggerbug, it's rare that any villain in any book gets what's coming to him or her. (Sylvester McMonkey McBean gets no comeuppance for conning the Sneetches. Of course, doing so would likely distract readers from the overall message.) His exception seemed to be characters responsible for their own undoing, such as Mayzie in Horton Hatches The Egg and Yertle The Turtle. Heel Face Turns where characters repent and amend their actions also occur, most iconically the Grinch. You can also make a case for the Once-ler, who too late saw that his actions ruined a perfectly good forest.
- Keep Circulating the Tapes: In 2021, the estate of Dr. Seuss opted to discontinue publishing new copies of And to Think That I Saw It on Mulberry Street, If I Ran The Zoo, McElligot's Pool, On Beyond Zebra!, Scrambled Eggs Super!, and The Cat's Quizzer due to racist imagery, which naturally led to an increase in demand for existing copies of those books.
- Kneel, Push, Trip: In One Fish, Two Fish, Red Fish, Blue Fish, a pair of fish do this to another fish while all three of them are underwater. The two doing the pushing are described as "very, very bad".
- Modest Royalty: In The Seven Lady Godivas, this is given as the reason why the sisters go naked. Apparently, they're taking this trope to its illogical extreme.
- Missing Episode:
- His very first attempt at a children's book was a simple alphabet primer with animals shaping themselves into letters. It was rejected by every publisher he sent it to and eventually disappeared en route to yet another and has never been found. He did eventually write an alphabet book— simply titled "Dr. Seuss's ABC"— but it had nothing to do with this one.
- Another book, with the working title The Pet Shop, was prepared for publication but for some reason never made it to press. It was posthumously discovered in a file folder and finally published in 2015 as What Pet Should I Get?
- And To Think That I Saw It On Mulberry Street, Scrambled Eggs Super!, McElligot's Pool, On Beyond Zebra! If I Ran the Zoo, and The Cat's Quizzer were discontinued in March 2021 and pulled from future publication and sales due to containing racist caricatures.
- A Nazi by Any Other Name: Well, Yertle the Turtle clearly wasn't one (and he wasn't truly evil, he was just greedy), but as Seuss himself said in an interview, he was meant to be an allegorical stand-in for Adolf Hitler and those of similar philosophical bent. (Though some of his original drawings had Yertle sporting a toothbrush mustache and wearing a Nazi uniform much like der Führer.)
- Non-Indicative Name: There's a Wocket in My Pocket! does not contain any Wockets in the book proper. There is one right on the cover, though.
- No Pronunciation Guide: Averted in a poem one of Seuss's friends wrote about it (This is from Dr. Seuss & Mr. Geisel: A Biography)I think that you are a duce
And you certainly shouldn't rejoice
If you're pronouncing it "soose"
The doctor pronounces it "soice".
- Nothing Is Scarier: The vug under the rug from There's a Wocket in My Pocket!. It is never shown, appearing only as a lump under a rug in a dark room, and the only detail the reader knows about it is that it's the only creature the narrator is afraid of.
- Old Shame: As mentioned previously, he felt pretty bad about his political cartoons demonizing the Japanese in the years after the fact. This regret likely extended to several of his other cartoons and ads mocking Jews and people of color years before he drew World War II propaganda. With the advent of World War II, many of the cartoons that he produced around that time decrying antisemitism, racism against African Americans, and bigotry in general — anti-Japanese sentiments aside — and he likely recognized that his old work perpetuated the problems that he would later take a stance against. Analysts would later credit this as a factor behind his estate's decision to pull six of his books from circulation for containing racist imagery.
- Only Six Faces: Even though the good Doctor is very good at defining characters, some of his male protagonists look remarkably similar to each other and to other characters, such as Herman "Butch" Stroodel of Daisy-Head Mayzie to the protagonist of There's a Wocket in My Pocket!.
- Mayzie herself looks similar to Sally from The Cat in the Hat.
- Parental Bonus: The entirety of You're Only Old Once! Geisel labeled it as a book for "obsolete children", because after his first adult book, The Seven Lady Godivas, flopped, he stated in an interview that "Adults are obsolete children, and the hell with them!"
- Perfectly Cromulent Word: Don't have a rhyming word? Just make one up!
- Posthumous Collaboration: Hooray for Diffendoofer Day!, fleshed out by poet Jack Prelutsky and illustrator Lane Smith following Seuss's death.
- Production Posse: When watching the television specials, expect to hear Thurl Ravenscroft, Hans Conried, and Bob Holt multiple times.
- Rain of Something Unusual: In Bartholomew and the Oobleck, the king tires of only rain, sun, fog, and snow coming from the sky, so he orders his wizards to come up with something new. Unfortunately what they create is basically a rain of glue, which nearly destroys the kingdom. This was inspired by a conversation he overheard during the Battle of the Bulge, with soldiers sick of the constant rain and desperate for any kind of different weather.
- Rhymes on a Dime: This guy does it every time, and in no way that is a crime! Most lengthened adaptations break it since it's hard to maintain, but will still stick it in every now and again.
- Rhyming Title: Inevitable. Given that most of his books are written almost entirely in rhymes, it'd be weirder if his extensive bibliography don't contain at least a few works with rhyming titles. Some examples include: Fox in Socks, The Cat in the Hat and Hop on Pop.
- Rhyming with Itself: In Dr. Seuss' ABC:Painting pink pajamas.
Policeman in a pail.
Peter Pepper's puppy.
And now Papa's in the pail.
- Sdrawkcab Alias: One of Seuss's pen names is LeSieg, which is his real surname (Geisel) backwards. More than one child grew up grumbling about these other beginner books that didn't have cool Dr. Seuss artwork and to be shocked when they learned this when they were older.
- Serendipity Writes the Plot: Horton Hatches the Egg came about when he was doodling out random things on transparent paper, and happened to overlay a drawing of an elephant over a tree so that it looked like the elephant was sitting in the tree, which started him thinking how it might have come about.
- Snake Oil Salesman: Zigzagged with Sylvester McMonkey McBean in the Sneeches story. What he sells truly works and does exactly what he claims, but he cleverly uses his Star-On Machine and Star-Off Machine to milk the Sneeches for everything they have got, playing on their attitude towards those dumb stars.
- Sneeze of Doom: Because A Little Bug Went Ka-Choo!. The whole thing escalates up to an entire town in absolute chaos because of that bug.
- Spiritual Successor: Oh Say Can You Say is one to Fox In Socks, as it consists of another batch of tounge twisters. The only difference is, Fox In Socks had a plot, and Oh Say Can You Say has no plot and the tongue twisters never connect to each other. Both books also start with the same warning.
- Supreme Chef: Assuming Peter T. Hooper, the protagonist of Scrambled Eggs Super, was telling his sister the truth, he was willing to go to the ends of the earth to get the eggs to make the best scrambled egg dish ever.
- Surprise Creepy: Thidwick ends in the unwanted guests being made into taxidermy.
- Thematic Series: His Dr. Seuss books are all linked thematically but aren't typically in any sort of continuity.
- Trampoline Tummy: Hop on Pop features two anthropomorphic bear cubs jumping on their father's belly, only for him to tell them "STOP You must not hop on Pop."
- Tulpa: The Glunk, in "The Glunk that got Thunk", a short story in I Can Lick 30 Tigers Today! And Other Stories. The Cat in the Hat's daughter uses her "Thinker-Upper" to bring a variety of usually cute and harmless thoughtforms into being temporarily. But one night ends up with a Glunk which promptly causes many problems such as racking up very large phone bills. She discovers that the Glunk cannot be UN-thunk by her alone and she and her brother have to cooperate to get rid of it.
- Unbroken Vigil: Horton Hatches the Egg. "I meant what I said, and I said what I meant. An elephant's faithful, one hundred percent."
- Uninvited to the Party: In Hooper Humperdink? Not Him!, a boy invites heaps of people to his party except for Hooper Humperdink, except later he changes his mind and invites Hooper anyway.
- The Unreveal: What Pet Should I Get? concludes with the two children deciding which pet to buy, but we never see what pet it is.
- Utopia: The protagonist's destination in I Had Trouble in Getting to Solla Sollew is a paradise.
- Weird Weather: Bartholomew and the Oobleck centres around a king who demands a new kind of weather of a group of wizards loosely attached to his court. He gets a rain of big balls of viscous goop called "oobleck" that rapidly floods the kingdom, trapping citizens and wildlife in its stickiness, as his long-suffering page boy Bartholomew Cubbins attempts to convince him to admit it was a mistake.
