The dancers are four girls who appear to be high-school cheerleaders, just like in the music video. Their dresses have the same design but different colors (all of them have been inverted except P1 in the remake) and different hairstyles, but they're all blondes (they all have black hair in Just Dance Now).
P1 is wearing a red cheerleader outfit. Her hair is short. She also wears a green hair clip. In the remake, her cheerleader outfit is now sky blue, and her hair clip is now pink and her hair is now black.
P2 is wearing a purple cheerleader outfit. Her hair is long, falling down her collarbones. In the remake, her cheerleader outfit is now lime green and her hair is now black.
P3 is wearing a blue cheerleader outfit. Her hair is tied in two pigtails. In the remake, her cheerleader outfit is now orange and her hair is now black
P4 is wearing a green cheerleader outfit. Her hair is long too, but unlike P2, she has bangs. Her hair is orange. In the remake, her cheerleader outfit is now dark pink and her hair is now black.
The girls are dancing in a locker room or a school corridor. The floor is checkered and the brick wall is pink. A school bell can be seen too. The lockers will occasionally light up and their doors will open or close. The same goes for the floor. At some points, the lockers act like a piano tiles.
In Just Dance 3, during the first Gold Move, P1 looks like she is about to fall, but she scoots her leg over and regains her composure. Also, at the beginning of the routine, she does a completely different leg motion than the other dancers. And after she does the second move, she accidentally does the moves after she hit the Gold Move the first time, then follows the rest.
This also seems to happen in the remake for P1 as well.
In Just Dance 3, the Gold Move pictogram for P1 instructs you to lift up your right leg, but you are meant to lift up your left leg instead. This doesn't happen in the Xbox 360 version.
There is a dancer with magenta pigtails that appears in the Mashup. It is a beta coach of the song, it was officially known because of the Soundless Quiz. She is seen again in the Mashups for Hit ’Em Up Style (Oops!) and Oops!...I Did It Again.
P4 has the same real-life choreographer as Boom. Both dancers also have the same hairstyle.
The Just Dance Now remake inverted the coaches' outfits colors. However, their original outfit colors appear in the same game via the You’re On My Mind Mashup.
In Just Dance Now, a few lines disappear too quickly and they are replaced by the following one; surprisingly, they aren't highlighted until they're sung.
This routine's Just Dance Now remake is seen in a number of Chrome Cast advertisements.
In Just Dance Now, the Gold Move effect does not appear in the preview.
It also glitches on Just Dance Unlimited sometimes.
In the line That somethin’ wasn't right here, the word here is absent.
Also, in the remake, in the line I must confess I still believe (still believe), still believe (the part in the brackets) is included in the lyrics with the line.
In the Just Dance Now remake, both of P3's socks glitch and turn white when she and P4 circle each other. This also happens throughout the routine.
The Just Dance Now bundle archives show four scoring detection files named babyonemorequat_goldceline, babyonemorequat_goldmanue, babyonemorequat_goldnatsuko and babyonemorequat_goldsandrine, which are references to the name of the performers.
Baby One More Time is the first song covered by The Girly Team.
If you look closely, P2 had a creepy smile during the entire dance.
