Appearance of backup dancers
The two males that appear in the background towards the start of the song are wearing boxes on their heads. They are blue and highly detailed. They are wearing jackets.They look similar to Video Killed the Radio Star.

There are also two girls wearing pink jackets and have pineapples on their shirts. One of the girls hair is poofy and resembles the Ghostbusters sweat version. The other one looks similar to American Girl, in style of hair.

The panda makes a reappearance, however he looks different this time. He is wearing a red/yellow headband, a radio around his neck, and red sneakers.

Classic
The background consists of real life shots (akin to Gentleman) with some animated effects. The real life shots are mostly underneath a concrete bridge, a residential area and a pool. There are some backup dancers dancing with him, consisting of men with TV's on their heads and leopard outfits, women with pink gangster outfits, a panda with a boombox necklace, and a disco ball headed man with a pink suit. There are Donuts as well.

Sing Along
The Sing Along background is the same as Starships' Charleston Mode's background, aside from two microphones which have been planted for the dancers.

Community Remix Mode
The song is the first one to have a community remix mode. The full remix was shown at the Ubisoft live stream. Just Dance sent about 15 people the full choreography for the people to send to Just Dance so that person's part gets featured.
