The dancer is a female with pink hair. She wears some cube and oval headbands, a yellow shirt with some chihuahua plush heads along with a square-pattern skirt that is shaped similar to a Rubik’s cube, some yellow and red spotted legging socks, and some black high heels with leg straps. At some points of the routine, the coach turns black and white. The dancer appears to be a paper cutout, as she seemingly peels off of the background revealing her to be flat, and completely white at the back.
The coach is a female that resembles Barbie. She has blond hair tied in a long ponytail with a pink headless cap, a pink crop top with the word Barbie written on it in several places, a golden necklace, a violet fingerless glove, purple tight pants, and a pair of pink sneakers.
The background switches between pink, blue, orange and green, with flowers, hearts, and sandwich ingredients in a monochromatic color scheme in the background. The word "Chiwawa" appears sometimes when it is said. Multiple Chihuahuas appear in most of the backgrounds. At the beginning, there are red, yellow, pink and purple flowers and the dancer appears to be walking a Chihuahua. It changes to a background with Chihuahuas and dog bowls in the background. The Chihuahuas sit down and touch their noses with their tongues at certain points. Near the beginning of the verses the background switches between a background with pipes with the dancer in a monochromatic color scheme coming out of them and cups with Chihuahuas coming out of them. Very random and usually animal-related objects appear during the chorus, such as hot dogs, carrots, rabbits and a gumball machine with dog toys dropping out of it. There is also a cropped Chihuahua head with the mouth cut from the rest of it, which has cucumbers slices on its eyes and sings into a microphone held by a hand. At the beginning of the second verse and the bridge, there are cats coming out of a photocopier; the second time they are coming out in sandwiches. There are also bowls of noodles flying around; at one point, the dancer in a monochromatic color scheme is riding on them. The last time she rides on them, her head is replaced by I Gotta Feeling’s. Near the end the background also contains dog bones as well as hearts and stars, also in a monochromatic color scheme. The entire environment appears to be made of paper. At the beginning and end there is also a Chihuahua wearing glasses that have the coach from Built For This on one of the lenses.

On the PAL cover, the Classic coach’s glove is purple, her hair is shorter, her shirt is pink, and her buns are missing.
The Classic dancer is featured on the PAL and NTSC box art.
The translation of "Wanko Ni Mero Mero" from Japanese to English is "Madly in Love With the Doggy".
Besides the sentence "The dog accidentally [gibberish]..." in Japanese, "I want a chiwawa" being spelled out in English, the word "Sorry!", "Let's go one more time!" and "Achoo!" at the end of the bridge, the song consists entirely of gibberish and Japanese onomatopoeia.
The audio was first released on the German Amazon website.
Chiwawa’s official release date was on September 29, 2015, which makes it the latest released song to be featured in Just Dance 2016.
They both appeared in the Beta version of the Dance Quest icon earlier.
At BGS (Brasil Game Show) 2015, a Community Remix for this song was seen in the menu. However, when the game was released, Uptown Funk’s Community Remix was included instead.
From March 23, 2016 to March 25, 2016, Chiwawa was free on Just Dance Now to celebrate "National Puppy Day".
In the Behind the Scenes video of the routine, Mehdi and Aurélie can be seen performing a move that is not present in the actual routine.
On the album coach for I Gotta Feeling’s Showtime, the animals that appear in the Classic background are detailed differently.
Also, the coach can be seen in the Showtime video itself. 
As seen on the PAL boxart, on the Just Dance website, and on the Youtube thumbnails the coach initially had different outlines. On the PAL boxart, it is yellow; on the website, it is purple and, on the thumbnails, it is a white outline without the paper effect.
The Wii U/PC version and the Xbox One/PS4 version of the alternate routine used to have the following differences:
In the Wii U/PC version, the dollhouse is seen as a plain purple silhouette, while the Xbox One/PS4 version applies some shading effects on it.
The Wii U/PC background is plain blue and its pattern has many B’s for Barbie, while the Xbox One/PS4 background has a gradient and has a pattern with chihuahua heads and the Barbie logo.
The chihuahua dog that sometimes pops up in the Xbox One/PS4 version is totally absent in the Wii U/PC version.
The background in the chorus is entirely recycled from the Classic routine on Wii U/PC, but it has some additional elements on PS4/Xbox One.
The Xbox One/PS4 version has some additional animations.
The cutscene where the coach rides a pink coupé with a chiwawa sitting on her left is not featured in the Wii U/PC version, although the car and the barking chihuahua can still be heard.
As of January 30, 2017, the video file on Just Dance 2016, Wii U and PC has been replaced with the one being used on the Xbox One and PS4.
A dance battle of Chiwawa, which Barbie needs to play to defeat the virus, is featured as the final level of Barbie Video Game Hero.
When the Remastered Version was first added to Just Dance Unlimited along with Don’t Worry, the routines did not have the "NEW" indicators, and they were only accessible through the Recommended section.
These errors have been fixed as of an unknown date.
It is the second Just Dance Unlimited exclusive to be free in the service, after Taste The Feeling (Aerobics Version).
The alternate routine is the fourth alternate routine in the series whose code name is not "(SongName)ALT". It is preceeded by the three Contest Winners for When I Grow Up, which are named "contest1", "contest2", and "contest3" in the files.
A different preview for the Alternate routine is featured on the official Barbie YouTube channel. It features the end of the song and has a different interface than other previews. The lyrics are visible and there are only four players instead of six.
In addition, instead of the "players" scoring randomly, they score only "GOOD" and "YEAH", and they all score the exact same amount of points, although only "Happy" has the crown.
In the dash.justdancenow.com video file, the pictograms have completely changed assets: the end of the slide has a different beat effect, and the pictograms pulse to the beat of the song and flash white before fading off; plus, the Gold Move pictograms (except for the last one) have an animated glow behind their torso.
