Berry Bitty City is abuzz as Berrykin Bloom introduces the biggest, juiciest, strangest fruit anyone has ever seen! It's the size of a house, shaped like a strawberry, colored like a watermelon and has a spiky pineapple top. "I call it the sparklestrawwaterpineberry!" says Berrykin Bloom. Princess Berrykin declares it the greatest achievement in Berryculture she's ever witnessed.
To convince the dance-averse Huckleberry to attend the big masquerade ball at the dog park, Blueberry promises she'll stay by his side the whole evening and make sure he doesn't have to dance. But as the day of the ball dawns, Blueberry awakens with a bad cold. She doesn't know how to tell Huck that she can't go to the ball. Lemon and Raspberry misinterpret her sniffles, thinking she's so heartbroken to be disappointing Huck that she's crying!
The girls plan a formal afternoon lawn party tea to inaugurate their new dog park. Plum is in charge of decorations, Cherry music, and Strawberry snacks. There's even a giant, dog-shaped ice sculpture. As the girls get dressed, Raspberry puts the finishing touches on the high-fashion hats that will accompany their beautiful gowns. At last everything is ready. But when the gate opens... the puppies back away!
With the power completely out in Berry Bitty City, the girls go on a camping trip to be out of the way of the Berrykin work crews. Lemon is nervous because she believes there is a creepy creature in the forest (that she read about in a book Blueberry loaned her), and the girls get the nervous bug, but Strawberry turns their apprehension into fun by daring her friends to stay out in the woods the longest!
Raspberry is discovered by a talent scout who wants her to move to Berry Big City and design a new line of Glitter fashions! She will be provided with her own studio, staff, publicity, commitments from big department stores-everything she needs to be a big fashion designing star! All her friends are thrilled for her. Only Cherry is a bit less enthusiastic about Raspberry's stardom, which Raspberry mistakenly interprets as jealousy.
Berry Bitty City is holding its first city-wide talent show! Hearing that it's the music students of superstar Cherry Jam, a talent scout from Big Bitty City plans to show up. Strawberry and her friends excitedly anticipate her arrival.
Cherry Jam is so enjoying staying in Berry Bitty City, that she calls her managers in Big Bitty City and informs them that she is going to stay for a much needed vacation! Strawberry and the girls are thrilled that she will be with them for a little longer, and they do all they can to make their guest comfortable. But Cherry doesn't want to be treated like a guest she wants to fit in and contribute to the community.
With time running out before the Grand Opening celebration for the new Marketplace, Strawberry's friends get the idea to invite her favorite singer, superstar CHERRY JAM, to be the guest singer. The girls are blown away when their berryjuice cell phone gets a text message that Cherry accepts their invitation! Strawberry is touched by their surprise, but reminds them that now the town and Marketplace really have to shine!
Strawberry is really touched when her girlfriends and the Berrykins volunteer to help her with the construction of her new marketplace, so when the girls suggest they take charge of designing Strawberry's dream-bedroom to go on the second story, of course Strawberry agrees. While construction is going on, the girls each show Strawberry their individual ideas for the bedroom.
After returning to the café after a walk with her pets, Strawberry is met by Mr. Longface. He's been waiting for her so that they can get started making treats and decorating for Sadiebug's and Kadiebug's party that afternoon. But Custard and Pupcake have enjoyed their time outside so much that they want to continue playing.
With all the Baby Berrykins running around Berry Bitty City, Princess Berrykin decides to build a Day Care Center and playground. But she's worried because it's dull-looking - all grey metal and brown wood. She asks Strawberry whom might be good to help her out. And two names immediately come to her mind - Lemon and Raspberry! The Princess confesses she's always admired their sense of design and style.
While working in her store, Orange overhears the Berrykins laughing and shouting outside. When she goes to the door to investigate, a clump of dandelion fluff gets blown inside chased by three Berrykins. She watches as they head butt the clump around until it floats back toward Orange. Just as it floats close, she gives it a bat sending it outside and the Berrykins happily chasing after it. Wanting in on the fun, she joins them.
While sipping cider in Strawberry's café, the girls muse about how they cannot wait for winter to arrive. They list the various traditions they love about the season but the one they all agree on is the Glimmerberry Ball. Strawberry mentions that she doesn't think the café can hold the party this year because of how the town has grown. The girls decide to split up and search for a new location.
Raspberry is distraught when she suspects her friends have copied her design on her lantern for the "Glimmerberry Gathering".
It's time again for the Dance-Off between the Big Bitty City Dance Team and the Berry Bitty City Dancers. Plum is stressed out and frazzled because she desperately wants to win. And the Big Bitty City Dancers are a force to be reckoned with. They are elegant and beautifully synchronized. Plum shows the girls a maze of dance steps that she's choreographed in the hopes of creating a winning piece. The problem is, the contest is only 1 week away!
While in the midst of a cake decorating demonstration at the café, the girls are uncharacteristically interrupted by an excited Princess Berrykin. She announces the Berrykins have decided to revive the old tradition of the Berry Bitty Buggy Derby. While the girls enthusiastically recount the stories they've heard about it and ask the Princess questions, Blueberry, carrying enough books to block her view, comes through the door and unknowingly interrupts the Princess.
