This is what you get when you combine Jim Henson puppetry with Dr. Seuss characters, along with some CGI animation for the settings.It aired from 1996 to 1997 and lasted for two seasons.
- Art Evolution: The first season used regular sets and props, while the second season used a "digital backlot" with the puppets performing in front of a green screen and a CGI set dropped in afterwards.
- Ascended Extra: Quite a few characters, including the Little Cats (who appeared in The Cat In The Hat Comes Back), and Morton the Elephant Bird (who appeared without a name at the end of Horton Hatches The Egg).
- Canon Foreigner: While many of the characters on the show are pre-existing Dr. Seuss characters, others were created specifically for the series. Two of the most notable are Sarah Hall-Small and Terrence McBird, both of whom debuted in the second season.
- Clear My Name: The episode "The Snoozer".
- The Complainer Is Always Wrong: This was the A-plot for many of the episodes of the second season. Usually, the Cat in the Hat and the Little Cats will engage in some kind of fun activity, but Terrence McBird will refuse to try it at first. When he does finally join in the fun activity towards the end of the episode, he finds out he actually had fun and it wasn't as bad as he thought it would be.
- Did You Die?: The episode, "Norval the Great" features Binky telling his friends about his adventures with his pet fish, Norval. In the middle of the story, one of his friends asks, "Did you and Norval die?". The others look at her and respond, "Duh...".
- Egg MacGuffin: The episode, "The Song of the Zubble-Wump" involves a girl named Megan and her friend Horton the Elephant trying to retrieve the priceless Zubble-Wump egg, which was stolen by The Grinch.
- Evil Chancellor: In "The King's Beard", Yertle the Turtle acts as the trusted advisor for two different kings.
- Massive Multiplayer Crossover: Many of the characters from many of Dr. Seuss' works combine to form the series' adventures. Notably, The Cat in the Hat is the show's host, and The Grinch and Yertle the Turtle are the series' recurring villains.
- Named by the Adaptation: The elephant bird who appears at the end of Horton Hatches The Egg is named "Morton" in the series.
- No Fourth Wall: Mostly used in season 2.
- Not on the List: In "Horton Has a Hit", Morton is trying to get into the theater where his father, Horton, is performing, to stop a World Tour that Yertle the Turtle is planning to take him on afterwards. The security guard refuses to let him in, telling him he's not on the guest list. Morton asks him who is, and he checks his list and tells him, "Everyone except Morton the Elephant Bird". Upon hearing this, Morton leaves, then comes back in a Coat Hat and Mask disguise so the Security Guard will let him in.
- The Other Darrin: Mostly for season 2, like Martin P. Robinson replacing Bruce Lanoil for the Cat in the Hat.
- Passing the Torch: In "Mrs. Zabarelli's Holiday Baton", after directing the Jingle Day pageant for 49 years, Mrs. Zabarelli retires and gives the job and her baton to her prize student, Annie DeLoo. The episode ends in the future, with an elderly Annie passing the job and the baton to her prize student, Arianna.
- Re Tool: The second season boasted a Two Shorts format, with a sub-plot involving The Cat in the Hat and the little cats from the second book serving as a Framing Device for each episode.
- Rhymes on a Dime
- Who's on First?: In "Horton Has a Hit", Fox in Socks and Mr. Knox do this kind of routine with Cindy Lou Who.
- You Mean Xmas: Jingle Day in "Mrs Zabarelli's Holiday Baton".
