Raspberry and Lemon want to join a fashion contest. They offer Strawberry to be their model, but she is too busy running both her café and the market. Raspberry and Lemon meet the twins Sweet and Sour Grapes, whose names fit their personalities and offer them to replace Strawberry in the café.

Apple Dumplin' comes to visit her cousin Strawberry. Soon she causes trouble: she installs a light/music display in Strawberry's bedroom, but cannot turn it off; later she causes a power failure. After Apple leaves, it is revealed that she fixed the power.

The twins' birthday is approaching. Sour says she does not wish to share the birthday with Sweet. Sweet is sad that her sister feels that way but respects her wish. Sour initially enjoys having a birthday of her own and the activities the Berry girls plan for her, but gradually feels lonely without her sister, and regrets what she said earlier.

The Berry girls go on their annual camp-out. Cherry, Plum and Orange become tired on the way to the camping site and stop to rest. When they catch up with the other girls, each of them has a different version of the adventure they had.

Sour implores Sweet to help her recount the Adventures they had in the Berry Deep Dark Forest, but her performance is so embellished that Sweet can't keep up.

At the camping site, Apple tells a story about the great race she participated and won, although the other competitors cheated and did their best to stop her by using dirty tricks.

Apple's rave review of Strawberry's dessert encourages the Queen of Berryvania to order her new cake for her ball.

Sour and Apple begin a prank war and they are sentenced in a Berry Bitty City-style trial to camp alone together for a whole weekend.

Berrykin Bloom's braggart cousin, Berrykin Bertram, has won the hot sauce competition at the local county fair year after year, but this year, Sour and Apple are determined to help the kindhearted Bloom win.

Apple joins Plum's ballet class. When she realizes she is not as good as the others, she decides to make a pair of dancing shoes which she calls "Groove Booties". But they escape and wreak havoc in the town. Apple must find a way to stop the Booties before they ruin the Berryball game.

Apple makes improved Groove Booties that can teach anyone to dance, including the puppies Pupcake and Pitterpatch. This gives Plum the idea to put on a show of dancing dogs. She asks Huckleberry if Tom Tom would like to participate, and he agrees.

Apple and Plum ask Cherry to compose music for the video of the dancing dog show so that it can be uploaded to Apple's website. Cherry is very busy writing a song for the queen of Berryvania but takes a break to do as they ask her.
