The coach is a woman dressed in cute, childlike 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.
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.

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.
