Barney, Baby Bop and the Backyard Gang have fun in a movie studio.

Sally gets a surprise when her three stuffed animals, Hum Bear, Melody Mouse and Barney the dinosaur, come to life and they take her and her brother Jonathan, along with Baby Bop and the Backyard Gang, and even their dog, Bingo, to a magical park to meet a marching band and celebrate her birthday party with her friends. They sing and dance and learn how to conquer their fears when a storm hits.

Barney and the Backyard Gang take the stage to delight and entertain everyone at Universal Studios in Orlando, Florida with Barney's new best friend, Baby Bop, who is a green dinosaur. They all work together to make a special surprise for the audience using items from "Shimbaree Shimbarah!".

On a Saturday, a little girl named Tina wishes that she could go to school with Barney and the Backyard Gang to do their musical routine. They even have their school pet, a hamster named Zippity. This episode marks the return of Adam from his illness.

After a long week of school, The Backyard Gang decide to have a sleepover at cousin Jimmy's house, they start talking about imagination and all of the fun they can have with it at the party. Just then, Barney comes to life, appearing to the kids. However, the kids are so busy that they don't recognize him. Barney taps them on the shoulders, when all of them get scared of each other. Barney asks the children what are they doing with all the sleeping bags. Which Tina replies to that they're having a slumber party. Barney, not knowing what a sleepover is, asks about what things they do at a slumber party. The children then reply all at once saying many different things. Barney calms them down. Barney asks them again, and the gang talks about playing games, singing, et cetera. The kids define a slumber party even more by showing Barney what they do at a slumber party, all through the evening and night, they play games, sing songs, and have so much fun!

Amy and Michael want to surprise their dad for his birthday. With the Backyard Gang in doubt, there's no way the show can be produced quickly (or, so they think). Fortunately, Barney the Dinosaur comes to life, and encourages the kids to use their imaginations to help make the show a reality. Along the way, they sing songs and recite rhymes that are later sung in the birthday show. The show ends up to be a success with Dad doing the "Hokey Pokey".

It's Christmas Eve and Santa's given Barney and his friends a special job -- to take Derek (the new boy in their neighborhood) to the North Pole to see if Santa knows his address. After arriving in Barney's special sleigh, the kids frolic on the ice, pretend to be elves in Santa's workshop and learn from Mrs. Claus that "doing things for others is what Christmas is all about."

On a hot summer day, the Backyard Gang is so excited to go to the beach tomorrow, but they could not go there because their dad has to go to work. Disappointed, no one knows what to do until Barney comes to life. By using their imaginations, Barney transports the kids to the beach in a flying swimming pool where they build sandcastles, collect seashells, eat peanut butter and jelly sandwiches for a picnic lunch, explore an old pirate ship, go under the sea and meet Barney’s friend, Molly the Mermaid.

On a boring Saturday afternoon, Barney and the Backyard Gang jump into Tina’s coloring book to grant three wishes for everywhere they want to go in their imagination.

Barney the dinosaur introduces the Backyard Gang to the fun of camping out. The children meet all sorts of woodland creatures, study the stars, learn valuable forest safety lessons, and best of all, discover the delights of their imagination.
