Each mane six's costume consists of a combination of the costumes worn by their pony-selves in both Halloween episodes.
Sunset Shimmer makes the decision to dress up as Nightmare Moon, but no one in her school seems to comprehend her costume.
Prior to and during the concert, the girls perform a particular role:
Twilight and Sunset team up to perform their favorite Halloween song as a duet.
Rainbow Dash and Applejack compose and perform some eerie melodies on their electric and bass guitars.
The role of costume crafter was played by Rarity, who crafted everyone's costume with great precision and care, except for Sunset's, who made her own costume.
Pinkie Pie stepped in to provide the stage with a Halloween feel and unleashed her electronic party cannons, which were filled with Halloween decorations and CANDY.
Lots and lots of candy...
She was also in charge of the after-concert snacks, which were spooky, sweet, and so, so, adorable.
Fluttershy, who was selected by her friends, is given the task of judging the costume contest that takes place after the concert. Upon being revealed as the winner, she is both shocked and delighted.
