The coach is a man with a mustache and beard. He is wearing a big red-and-yellow beanie over his head, that has hints of green also on it. He also wears a light green shirt, a red, green and white vest, a pair of red shorts as well as a pair of yellow sneakers. He also wears a golden necklace with a golden-yellow pendant.
The background is a city street with lighted buildings. Around the dancer are some speakers, lights, cameras, and wires, which may mean that the dancer is being filmed or perhaps basking.
There are 4 Gold Moves in this routine: All Gold Moves: Flip your arms up and down. Note that these moves are done consecutively at the start of the bridge (When the line Come on and shake it! Party girl! is sung.)
In the preceding Just Dance games, the pictogram color is orange. In Just Dance 4, the pictogram is red.
Also, when the dancer is swinging his arms, the pictograms depict the arrows as purple but in the downloadable version of the routine, they are yellow.
On Just Dance Greatest Hits, the song can be unlocked with a D-Pad code. The code is Up-Up-Right-Right-Down-Down-Left-Left.
This is one of two songs that can be unlocked with a code. The other is Katti Kalandal.
This is one of the few songs without an HD remake in Just Dance Now, along with Dagomba, Boom, Cosmic Girl, Professor Pumplestickle, and others. This could be attributed to the fact that they were HD remade for Just Dance 4 when they were released as DLCs (besides Cosmic Girl and all songs that were released in the game later those ones).
Along with Die Young and Primadonna, this song is one of the final DLCs to be released for Just Dance 4.
Also, along with the same two songs, this song was accidentally released for a brief amount of time on the PlayStation Network during late-March 2012 for Just Dance 4.
There is a photo showing the dancer from Let's Get It Started with a background and the background in the photo is highly similar to this song's background, but the cameras and everything else is missing, so it is possible that this song replaced Let's Get It Started.
In Just Dance 3 for Xbox 360, the Shake icon is identical to the Gold Move pictograms for this routine.
When the player completes 1 up to 4 Gold Moves on Just Dance Unlimited, they will gain five stars but the star bar doesn't reach the fifth one.
Two pictograms for the remake were changed after the release on Just Dance Now. The former versions had a spiral arrow, which is removed in all the later appearances.
Baby Girl is one of 13 songs in Just Dance Unlimited to be from a main series game earlier than Just Dance 4 to have differences between the square, cover, and half dancer poses. In Baby Girl‘s case, the pose on the cover is different to the square and half dancer poses.
