The coaches are dancing in front of a pink 2D city full of skyscrapers and cliffs. It almost looks like blueprints/drawings. A giant robot and a monster can be seen attacking the city. During the bridge, an iron spaceship comes from above and creates five lights, and the lights have the same colors as the coaches' suits, and follow their arm moves.

Both this song and Nitro Bot appear in a total of four games each.
Based off the name and the dance, this song is mainly referencing the Super Sentai series, which at the point of its release was in its 35th anniversary season, Kaizoku Sentai Gokaiger.
Additionally, the song sounds similar to the opening of Choudenshi Bioman, a Super Sentai season that was very popular in France in the 1980s. Therefore, it's very likely that the developers intended on referencing a show from their childhood.
Most of the footage from Super Sentai was used to form the Power Rangers series.
The song was shown in the tutorial booklet for Just Dance 4 on Wii.
