Sue Snue is sent on an important mission: to deliver a box filled with precious gifts to Regina, the Queen of Ka-Larry. With Fox in Socks and Mr. Knox as her escorts, she must do whatever it takes to get the box to the Queen...even if it means getting there with a slightly lighter box.

Yertle's Aunt Myrtle (a bona-fide queen!) has left Yertle temporarily in charge of her kingdom while she is away. Big mistake.

When Yertle hears Horton singing a lullaby to Morton, he knows that Horton has what it takes to make it to the top (and to take Yertle with him). Horton must leave the suddenly-popular Morton in the care of his Uncle Norton as he goes on tour. Is all of the fame and fortune worth it?

Thidwick is so excited... it's his birthday, and just like every other year, the Birthday Bird will take him (and all of the other birthday celebrants) to Katroo for a huge party. But when word comes that the Birthday Bird is unable to make it this year, Thidwick decides to take charge and lead everyone to Katroo himself... disguised as the Birthday Bird!

The Cat in the Hat has left Little Cats A, B, and C alone with a nifty storytelling machine, and when they insert a backscratcher, they hear the story of how the Grinch and his dog Max came to be friends. When they insert a half-eaten cake, they are told the story of Alvin, an alien from Malamaroo. Alvin is as sweet as can be, but he drives Jane, Junior, and Thidwick crazy when he never finishes what he starts -- including his trip home!

In the Cat’s Playhouse, Terrence McBird is cranky because he refuses to take a “cat nap.” Will the Cat, Sam-I-Am and the Little Cats be able to help? In the Wubbulous World, Sarah Hall-Small encounters the scary-looking Yapper-Nap, who frightens everyone in Seussville, but he’s actually just sleepy. We also see what our friends in the Wubbulous World dream about.

In the very messy Cat’s Playhouse, when the Cat in the Hat loses his bow tie, it’s cleaning time! That is, if he and the Little Cats ever get around to it… In the Wubbulous World, we meet Matthew Katroom, who battles his messy room. And Yertle the Turtle sells Jane Kangeroo a new kind of mess-free Turtle Tree.

In the Cat’s Playhouse, it’s Terrence’s birthday, and he thinks that everyone has forgotten. Actually, they’re all planning his surprise party… In the Wubbulous World, Felix Finkledooper celebrates an extra-special 8th birthday, while Princess Tizz is sad because all of her birthday presents are too rare and precious to play with.

In the Cat’s Playhouse, Terrence has a nasty case of the hiccups...what to do? In the Wubbulous World, Sarah Hall-Small has a hard time choosing what instrument she wants to play in the Seussville band. And when Horton and Morton go exploring in the jungle, Morton learns that scary sounds aren’t always scary things.

In the Cat’s Playhouse, Terrence thinks that the Cat’s house is boring. How to convince him otherwise? In the Wubbulous World, Morton, wanting to be more bird-like, searches for a nest with Junior kangaroo, and Sarah Hall-Small draws pictures of where she might like to live.

In the Cat’s Playhouse, Terrence is having trouble with his flower, a purple and pink Happiola. In the Wubbulous World, Milo plants a tree and imagines all the wonderful things it will grow to do, and the Grinch plots to put a stop to the joyous Blinky Blossom Festival.
