Cowntess, just back from a world cruise, is showing some of her home movies from the trip. Globey teaches Pee-wee how to say "hello, my name is Pee-wee" in French and Chinese! When a lost puppy appears at the Playhouse door, no one can figure out who the owner is. Pee-wee develops a strong case of puppy love and decides to keep him and name him Aloysius. However, Reba comes "over," and it's obvious just whose dog it is.

Pee-wee and Cowboy Curtis take a leap into Magic Screen where they enjoy some mighty fine handcart ridin' until a train chases them back into the waiting arms of Chairry! Then, Cowboy Curtis sings a song with "more" of the secret word in it than you could scream at. Finally, Cowboy Curtis and Miss Yvonne go shopping at Pee-wee's "department store" where they decide to buy Chairry!

Nothing bugs Pee-wee's flowers more than having a caterpillar in their flower box until Magic Screen shows how a caterpillar can turn itself into a beautiful butterfly. The caterpillar's not the only uninvited creature around when Cowntess has a birthday party and invites practically "all" of Puppetland except Pee-wee! Is she mad at him or just being moody?

Today, Pee-wee gives everybody "That Certain Feeling" by lip-synching to one of his old records. Later, while Pee-wee is out with the Playhouse Gang, Cowboy Curtis comes over and sings to the flowers, and Miss Yvonne does a wild clog dance. Tensions mount when the gang ends up with two "cool" ice cream desserts, and they have to choose which to eat. Of course, they could just eat them both!

Learning is "easy" when your teacher makes it fun. No one can make it more fun than Pee-wee, especially when he turns the Playhouse into a schoolhouse! The Playhouse Gang are his students, Magic Screen is his blackboard, and Globey is, well, his globe. Pee-wee makes history exciting when he teaches about Christopher Columbus and the Declaration of Independence. Sit back, laugh, and learn!

As the Spring season comes to "begin," Pee-wee plants a seed, and it grows quickly (courtesy of Clockey). Also, the King of Cartoons presents his wife, "The Queen of Cartoons," and his son, "The Prince of Cartoons." Also, when Pee-wee doesn't make the baseball team, Ricardo shows him that there are other sports he can try.

Aaaaugh! The secret word is "zyzzybalubah," and that can only mean one thing! The entire Playhouse, including Reba, is sucked into space, transported to a strange planet, and taken over by an odd, lonely alien! Yvona, an alien from the planet, is trying to escape the unfriendly Zyzzybalubah, but Pee-wee teaches him how to be polite and make friends. Reba teaches Pee-wee how to whistle, and she sings a song.

Guess who's having a pajama-party sleepover? That's right, it's Pee-wee along with his co-hostess, "the most beautiful woman in Puppetland," Miss Yvonne! Jambi's got a head for pajama fashion when he gives Cowboy Curtis a Wild-West pair of P.J.s! Wacky Roger, the Monster, keeps an eye on things as Pee-wee decides that, since he loves his fruit salad so much, he's going to marry it! "Watch" for the secret word!

Pee-wee wants a letter mailed, so he asks Jambi to make Reba appear at the Playhouse. This makes Reba mad because it's her day off. Pee-wee convinces her to stay for an imaginary breakfast of oatmeal and potatoes. Meanwhile, Pterri disappears when Pee-wee sends him to his nest for being naughty. The Playhouse gang blames themselves for Pterri's punishment until Pterri comes back - from hiding underneath the bed! Watch, "now," and you'll have a "Pterri-fic" time!

Pee-wee has to eat his words when he tells the gang how important dental hygiene is and, then, develops an ow-some toothache! Since Jambi is taking a head-turning vacation at Mount Rushmore, Pee-Wee is forced to face his greatest fear - the dentist! He's so afraid, it'll take Miss Yvonne's coaxing just to get him to go. When he finally does make "it," Pee-wee learns that visiting the dentist is nothing to grit his teeth over and can actually be fun.
