Birthday

"Birthday" by Katy Perry is featured on Just Dance Epic Hits.

Appearance of the Dancer
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.

Background
The background has a pastel scheme. There are also pictures of cake and confectionery appearing. The cake reads "Birthday". It is supposed to give the dance a birthday feel. You can see many macaroons around and you can also see them with candles lit.

Gold Moves 1, 3, 4, and 5: Throw both of your arms up in the air while you lift up your right leg.
