The coach is a girl dressed in cute, childish attire. She has pink bobbed hair, a green T-shirt with a pastel yellow and blue collar and some dark blue stripes, a high-waisted belt with blue stripes held by two circles (a red and a light yellow one), a red skirt with pink polka dots, two circles (a light yellow one and a green one) with dark blue stripes and green and pastel blue rectangles on the bottom, green socks, and red heels with a blue highlight. She has a white thin outline over a thin periwinkle outline in full opacity.
Background
The background is full of pastel geometric shapes. Fruits, vegetables, and pairs of dancing/jumping legs appear throughout. A polar bear makes a few appearances; numbers and Chinese characters appear during the pre-chorus and between the second and third choruses.

Gold Move 3 (Gold Move on Just Dance Unlimited and Now): While bending over, stretch your arms out and bend your feet so that only your heels touch the ground. Gold Move 4 (removed on Just Dance Unlimited and Now): Transfer both arms from left to right with your palms facing the ground, while bending your left leg and then your right one.

Trivia
General
Leg Song is the first Chinese-language song in the series that features Japanese lyrics.
In 舞力全开2017, in the lyrics, "Lulu" is spelled as "L U L U"; in Just Dance Unlimited, instead, it is spelled as "LU LU".
In Just Dance Unlimited via Wii U, the song title appears as "??? (Leg Song)" due to the console not being able to detect Chinese characters.
Lyrics that are in Cantonese are replaced with Pinyin lyrics.
Romaji lyrics were removed in the Just Dance Unlimited version.
The routine was later removed from Wii U versions for unknown reasons.[citation needed]
Before fixing this mistake, however, when the player tagged for "2017" from the search tab, 腿之歌 (Leg Song) would still appear under the list of routines from Just Dance 2017.
Much like Qia La Yong Yuan OK - Future Underworld Mix, the lyrics used to[4] be absent on Just Dance Unlimited and Just Dance Now[5].
In an update of the former, romanized lyrics were added to both routines; however, every capital letter is in uppercase.
In Just Dance Now, Leg Song was erroneously placed at the end of the "All Songs K-R" playlist.
On May 15, 2019, it was properly placed in the playlist.
In Just Dance 2019 and Just Dance Now, the song title is displayed as "腿之歌 (Leg Song)"[6]; in Just Dance 2020, instead, "腿之歌" and "Leg Song" are placed the other way around.[7]
Three pictograms from 舞力全开2017 have been slightly edited in the Just Dance Unlimited version.
This makes Leg Song, along with Qia La Yong Yuan OK - Future Underworld Mix the seventh and eighth post-Just Dance 3 to receive changes in their pictograms.
The routine uses moves from the official music video.
Although the pictogram for Gold Move 3 instructs players to clumsily walk backwards and rigidly shake their arms, one must simply stretch their arms out to earn points, as the backwards walk is not counted.
The coach’s avatar was first found in the files of the Just Dance World Cup website.
The square and coach selection images can be found in the files of the Nintendo Switch version of Just Dance 2017.[8]
Leg Song, along with Qia La Yong Yuan OK - Future Underworld Mix, was added to Just Dance Unlimited to celebrate the Chinese New Year.
They were the last two songs to be added outside of a Just Dance Unlimited season event until Drum Go Dum.
