Loonette has to teach Molly that there are certain times when the word ""no"" is used. Snicklefritz learns this the hard way after his wild ways cause Major Bedhead to hurt his knee. Near the end of the program, Loonette reads an extended version of Mary Had a Little Lamb.

Granny Garbanzo is holding a sleepover in her garden. Before Loonette can go over, she has to fix an alarm clock and give Molly a time-out. It turns out Granny has to give Snicklefritz a time-out of his own. But everyone shares in the sleepover, including Auntie Macassar, who brings an inflatable cot.

Molly wants to get Loonette's attention by playing a rock music cassette at an ear-splitting level. Loonette tries to tell her to wait her turn. But the tables turn on Loonette when she cuts off what Major Bedhead wants to say.

Molly keeps asking ""Why?"" (thought bubble with a question mark), leaving Loonette a tense little clown. Yet both discover that this tensing and relaxing is good for them.

After teaching Molly about echoes, Loonette decides to copy everyone. This spills out into Granny Garbanzo's garden. When Granny objects to Loonette's mocking, she dresses up to mock Loonette!

It's National Horseplay Day, an uproarious good time for every clown–but not for Snicklefritz. Who can get him to start laughing?

Loonette gets an interesting perspective of her couch and Granny Garbanzo's garden. When Major Bedhead crawls along, he helps Loonette tame Snicklefritz, who is intent on playing leapclown. Auntie Macassar's succession of picture postcards show Loonette how to view the various parts of the world from various unusual directions.

Loonette tells a few fibs to Molly and then Major Bedhead. Neither believe Loonette because she is squirming like a worm–a dead giveaway, for sure.

Loonette and Molly have fun with falling down safely. The unforgotten rule is: Don't keep your hands in your pockerts.

Loonette feels the need to travel. She and Molly set their zigzag compass to go to Clowntown, but Granny Garbanzo and Major Bedhead keep them at bay. While both Loonette and Molly are too young to go to Clowntown by themselves, they can travel in their imagination. It sets up a costume piece with Granny as the Tour Guide and Major Bedhead as the Captain on their Boat of Imagination.

First Loonette, then Molly, can't get rid of their hiccups. They set out to Granny Garbanzo's garden, where everyone suggests crazy cures–even Auntie Macassar, who drops in for a ladies' tea.

What happens when Loonette decides to take everything out of the couch? She learns about empty and full the hard way. And in Granny Garbanzo's garden, after befriending a caterpillar, Loonette understands the expression ""full of life.""
