When a mysterious box shows up in the backyard of the Blue's Clues house, Steve is disappointed to find that it's empty, but Blue shows him that by using imagination, the box can be anything one pretends it to be. We use this idea to have a lot of fun, pretending that the box is anything from a car to a rocketship. Shovel and Pail manage to get three different uses out of it. We even use it to make it to the top of a high tower in the Blue Skidoo segment.

In this episode, we use our imaginations to go on a big adventure. We're in Queen Blue's kindgom and are trying to rescue King Horace, who has been captured by Periwinkle, the Kitten Castle Keeper. We have to think creatively to overcome his magic obstacles. Then, finding our path blocked by a lock, we skidoo into a storybook and must solve a series of riddles to obtain a magic key.

Steve and the Blue's Clues characters are all pretending to be superheroes. Steve is Stripe Man, Blue is Super Blue and there's also Clock Girl and Super Soap. Together, with us the viewer (The Incredibly Helpful Friend) we're The Thinking Squad. Together, we use our superpowers to solve a number of problems. We help Paprika find her missing Teddy Bear and help Mr. Salt at telling time. In the Blue Skidoo segment, we help a friend named Frank to find out just what his superpower is and help out two other friends in the process.

What's new? Blue and the Blue's Clues characters are trying out new things and so Blue and Steve decide to create ""Blue's News"" to document it. See Blue rollerskate, Pail try playing basketball, big news about Paprika, Mr. Salt and Mrs. Pepper and more. That's the news - now everyone knows.

Blue has a new place. Steve and the viewers gather what is new in her place. We also see Paprika's new place.

With Mr. Salt and Mrs. Peppers' new baby on the way, Blue and Steve have decided to create "Mr. Salt and Mrs. Pepper Day" to honor them for all of the things they do to help everyone. Throughout the day, we try to help them out, from helping them to clean the kitchen to learning about their favorite things. They're also presented with a number of gifts carefully crafted to show them the things the characters appreciate about them. All of this is a great help to them - not only to relax, but also to feel very appreciated for all their hard work.

We've been waiting and the moment everyone's been looking forward to has finally come: Mrs. Pepper is ready to have her new baby. While she's at the hospital and we wait for Mr. Salt's phone call, we do things like look at baby albums to pass the time. Later, we visit the baby hospital with Blue, Steve and Paprika and meet the new baby. Finally, the baby comes home and we give it a special welcome home.

Now that Cinnamon has come to the Blue's Clues house, it's necessary to make some changes to keep him comfortable. That means that things such as loud games are out when Cinnamon is trying to sleep - but we learn that by just thinking a little, we can come up with changes that will let us still do the things that we want to do, but in a different way. Sometimes the changes aren't easy at first, but they help others and aren't really that much of a problem. In the spirit of change in helping out, we also try to find ways to help Mr. Salt and Mrs. Pepper take care of Cinnamon.

Steve and Blue are going on a bug-watching expedition and we're invited to come along. We help them to spot many neat bugs and once we've found them, we learn more about them and also theorize about why they do the things that they do. We also skidoo into a big bug book. There, we meet up with Antoinette, a worker ant on the first day at the job.

Periwinkle missed his friend from the city, Plum, for a long time, but now he's finally come over to visit. Plum is a small purple bird who knows how to speak both Spanish and English. Throughout the episode, we learn how to speak Spanish words and also help out our friends. We learn Spanish as we help Periwinkle and Plum to create a marioneta. We also skiddoo into a puppet book, where we find Pedro, who needs our help in finding things to wear, so we use both Spanish and logic to figure out the right things that he needs.

The finding of a secret lost door gives us the opportunity to talk about things that are inside other things. For example, we play the "Grocery Game" with Mr. Salt and Mrs. Pepper. This involves placing various food items on shelves based on what's inside them. We also get to skidoo into a pull-tab book, where we find many interesting things inside the tabs.

Blue's friend Green Puppy is over visiting with Blue at the Blue's Clues house and we're all having fun with blocks - Steve and Blue constructing towers with our help and Green Puppy knocking over towers of her own. We learn about concepts such as balance, shapes and as we construct. A Blue Skidoo segment offers a look into architecture. We help an architect to select shapes to build various structures based on blueprints that he's created.

Steve is all dressed-up in t-shirt and sport pants as we head out for Blue's Backyard Ballgame Bonanza. It's a fun-filled event containing all sorts of different ballgames. We help out our friends with the games by acting as a coach and telling them how they can make the balls do the things they want. We also have fun with Steve's invisi-ball and later skidoo into a stadium where we assist Steve in making sense of an obstacle course filled with ball challenges.

Steve's brought out our old friend sock puppet and he encourages us to join in too by using our hand as a new puppet, "Handy." We tell stories together using both of our puppets. We also help out Tickety Tock and Slippery, who have puppets of their own and want to tell a story, but aren't sure how to express emotions using their voices. Later, we skiddoo into a poster of a castle and become puppeteers to help out a character named Storybook.

In this episode, we help the various characters to come up with words that rhyme with things they're saying. Rhymes are words that have the same ending sound as another word, such as "say" and "hay," or "head" and "bed." Lullabies usually rhyme and so we help Mr. Salt to create one to get Paprika and Cinnamon to sleep. We also skiddoo into a rhyming storybook. There we help out several characters whose stories aren't quite right because one of the things in them doesn't rhyme with the other two things.

In this episode, we use our imagination to see, feel and even taste things that we wouldn't be able to otherwise. We tell a story with Blue, Tickety and Slippery Soap using pictures and our imaginations. Unfortunately, Mr. Salt doesn't seem to understand the whole imagination thing and so he doesn't see what we're seeing. Together with Steve, Periwinkle and Blue we come up with a special song to help Mr. Salt find his imagination.

Blue has her own book nook where she's organized her books into sections. We read some of the books and also help out some of the characters to find books that they need to help them out with things. Later, we visit the library, where Marlee the librarian helps Steve to find a book about elephants. We learn about reading, categories, classification, the alphabet and more.

In this episode, we explore all sorts of dances. We learn that all sorts of movements can qualify as a dance. In the Blue Skidoo segment, we find out that a person who works to create dances is called a choreographer. We help Steve and Blue to aid the choreographer in performing a new dance of his.

Blue is the teacher at her pretend school.

Blue figures out something to do today.
