The dancer is a woman wearing a birthday/sweets-schemed costume. She is wearing a pink and sky blue top with sprinkles, a yellow and pink layered skirt, yellow polka-dot stockings with pink cupcake prints, and blue high heeled boots. She has long marigold hair tied in a ponytail braid and is wearing a floral wreath made of teddy bears and button flowers. She is wearing very heavy makeup consisting of blusher and eyeliner.
World Dance Floor VIP
The dancer is the performer of the Classic routine, Aurélie Sériné. She is wearing a white bralette with a sweatshirt tied around her waist. She is also wearing waist high black pants with white sneakers.
Background
The background has a pastel scheme. There are also pictures of cake and confectionery appearing. The cake reads "Birthday". Many macaroons can be seen. They are also seen with candles lit.

There are 5 Gold Moves in the Classic routine:

Mashup
There are 2 Gold Moves in the Mashup, both of which are the same:
Both Gold Moves: Open your arms. (Part Of Me) (Note)
The coach lip syncs "Happy Birthday" every time the line is sung.
The dancer was used in promotional content for E3 2014, in spite of the routine being revealed later.
In the preview video, the arrows for the pictograms were dark pink, despite the glove being red.
In some Beta gameplay snapshots, the coach appears to have a blue glow instead of a solid border like in the final version.
In others, the coach’s outline is orange instead of blue.
When unlocking the avatar for Birthday in Just Dance 2015, the lipstick is absent. However, when the avatar is viewed in the Avatar Shop, the lipstick appears.
The routine is affected by a bug in Just Dance 2015: sometimes, a black screen covers everything but the GUI. [3]
There was a VIP on the World Dance Floor named Aurélie during most of November 2014. Players could dance with her while this song was played on the World Dance Floor. As of January 2016, it came back.
Birthday won in the Favorite Choreo category on the second Just Dance Awards. [4]
The background was used in a promotion for Ubisoft’s new logo.[8]
On Just Dance Now and Just Dance Unlimited, the B for "birthday" in the line "Happy birthday" has been capitalized as of an unknown date.
The routine is used in the June 2018 version of the Just Dance Now tutorial screen.
In the event held on Just Dance’s Twitter account to choose the Just Dance coaches for the new music video for Nails, Hair, Hips, Heels, the coach is referred to as "Chiffon".[9]
Mashup
The dancers for all the songs by Katy Perry, except Roar, are featured in the Mashup. It is the only Mashup whose theme is based on an artist who appears in the Just Dance series.
Birthday (Mashup) is the first Mashup to feature a coach from any non-Solo routine (in this case, the lead coach from Dark Horse, which is a Trio).
This happens because P2 was recorded separately from P1 and P3.
Birthday (Mashup) is the only Just Dance 2015 Mashup that features at least one coach from every game of the main series.
Birthday and Love Is All’s Mashups are the only ones in Just Dance 2015 to feature the Classic dancers in the middle of the Mashup, as opposed to only at the start and end.
Birthday’s Mashup does not have the Gold Moves from Part Of Me on the PS4.
