On the day of the Grand Galloping Gala, Pinkie Pie, Rarity, Fluttershy, Applejack, and Rainbow Dash gather outside the Carousel Boutique and watch as Twilight Sparkle performs a new magic spell to transform an apple into a fancy carriage.

Rarity spends time with Celestia's nephew, Prince Blueblood, hoping to fall in love with him, only to discover that he is self-absorbed and obnoxious.

As events mount, the friends' actions lead to a mass of chaos in the grand ballroom when Pinkie Pie causes a cake to fly towards Blueblood, who uses Rarity as a shield against the splatter, and the animals burst in while fleeing Fluttershy.

"The Best Night Ever" was directed by Jayson Thiessen (supervising) and James Wootton, and written by Amy Keating Rogers.

Prince Blueblood, Rarity's selfish love interest, was originally meant to be a duke, but a member of the approval process believed the target demographic would be unfamiliar with the term.

[4] "At the Gala", recorded at Bryan Adams's studio in Vancouver, includes a choir of twenty people with each main character singing a solo part.
