Synopsis
Rarity takes a summer job as a costume designer for a new amusement park. Meanwhile, the chief costume designer, Vignette Valencia, is once seen trying to have a salad, and when she tries to post a picture on social media, her phone sucks the salad into it. Vignette wonders how it is possible, and likes the new feature. Rarity meets Vignette and designs costumes for a special parade at the amusement park. On the day of the parade, she invites her friends, Applejack, Rainbow Dash, Pinkie Pie, Fluttershy, Sunset Shimmer and Twilight Sparkle. Vignette then decides to put up the Rainbooms on the parade.

When Fluttershy meets with Vignette, Vignette puts up her suggestion on Fluttershy's look for the parade. But Fluttershy disapproves of it and is zapped into the phone unexpectedly by Vignette. Applejack looks for Fluttershy, but cannot find her. Soon, Vignette puts up her suggestion on Rainbow Dash's parade look, but she disapproves it and is also zapped up into the phone. The two end up in a white place with the salad that Vignette zapped up in the beginning. Applejack then sees footage that exposes Vignette's true colours to her. She now looks for Rarity to warn her about Vignette but she does not believe her, which turns into a confrontation after Vignette denies any sort of such zapping, upsetting them both. In the mean time, she zaps up Pinkie Pie, Sunset and Twilight when they disapprove of some over-the-top looks. They are all locked in the white place and meet Rainbow Dash and Fluttershy, sharing each other's stories and trying to get out. Vignette prepares for the parade by projecting fake versions of the Rainbooms and designing them the way she wants. She then reveals her plan to Rarity and tries to zap her, but got away

Rarity finds Applejack and tells her that they cannot let Vignette perform at the cost of losing their friends. They phone call their friends, and when Applejack opens a door, they find her friends trapped in a room in the park. Believing Vignette will teleport anything she does not like into the room, they head to the parade to stop her. All the Rainbooms use Equestrian Magic and release a Rainbow Laser to free Vignette's phone from the Zapping Magic. Vignette feels devastated, and tells that she did this because she had the philosophy of "BYBB" (Be Yourself But Better). Rarity then explains that we must not be better at the cost of harming our friends. Vignette then reveals that despite having so many fans, she does not have any friends. Rarity and Applejack offer friendship, and things end on a happy note with the Rainbooms performing the song "Photo Booth" at the parade, led by Rarity and Applejack, and having loads of fun at the amusement park.
