- Animated Adaptation: Numerous, including two feature films.
- Anvilicious: Seuss's aesops are not delivered gently.
- Interestingly, he usually didn’t write his books with morals in mind. He preferred to let it grow out from the story, saying “A kid can see a moral coming a mile away.”
- Covered Up: The Red Hot Chili Peppers did an adaptation of "Yertle the Turtle".
- Crazy Awesome: The circus and zoo featured in If I Ran The Circus and If I Ran The Zoo.
- 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.
- Fair for Its Day: Seuss's attitude towards the Japanese would not go over well today, but it was nowhere near as extreme as many people's at the time.
- Heartwarming Moments: The Lorax originally had the fish, chased out of their lake by pollution, say that "I hear things are just as bad up in Lake Erie". But "People indeed cared a whole awful lot,/ And worked very hard, and better it got." (to paraphrase the book's ending) - and so Dr. Seuss removed the line.
- Misaimed Fandom: Horton Hears a Who has been co-opted as support by many pro-life groups, who use the famous line: "A person's a person, no matter how small" as their rallying cry. In truth, Seuss was commenting on how America was basically ignoring the rebuilding needs of post-WWII Japan, and that line in particular was intended to send the message that regardless of the fact that we had just fought a war against them, treating them that way was simply not right, and would probably engender further resentment against the United States.
- The man himself wasn't pro-life and sued a pro-life organization for using the phrase on their stationary.
- Some Anvils Need to Be Dropped: If the book has An Aesop, it comes with absolutely no subtlety and is better for it.
- Tear Jerker: The Lorax is a good contender for the saddest Dr. Seuss book of all time. It proves that, indeed, Some Anvils Need to Be Dropped.
- What Do You Mean It's for Kids?: The nudity in The Seven Lady Godivas, some other books involve guns and killing.
- The Woobie: Horton and Thidwick, Oh so very much.
- The Lorax, poor soul.
