Barbie is ready to spend Sisters' Fun Day!, the one day a year devoted to Barbie spending it with her sisters, when Barbie gets an emergency call from Fifth Harmony to be the director for their music director since their old director got plastic pox. Not only does Barbie have to be in two places at once, she also has to deal with the onset of flipquakes.
The title is grammatically incorrect; it should be Sisters' Fun Day.
As Raquelle drives her bumper cart out of the arena and crashes, the famous stock sound effect known as the Wilhelm scream can be heard.
This is the first, only, and last TV special where the characters don't have pop-up name slides.
This is the first, only and last TV special and least episode where Barbie wears the outfit she wore in the beginning of the TV special: a blue letter jacket or letterman's jacket with white sleeves that are mid-length sleeves with grey, extra-attachment at the bottoms of them and the jacket has a pink "B" on the left side or right-hand side, much like Nikki's Season 2 outfit, the necklace she's worn in the outfit in "Oh How Campy" and furthermore with that outfit in "Closet Princess 2.0", and the same bracelet she's worn with that outfit, a grey shirt with white polka dots, the same pink earrings she's worn with the grey jacket outfit she's worn in "Oh How Campy", and pink pants, and the same shoes she's worn with the latter outfit.
On Netflix, it is called "Sister's Fun Day" but on the Barbie.com/Dreamhouse weblink for "videos", it is called "Sisters' Fun Day!" with an exclamation mark.
