P1 is a male cowboy with a mustache and a blue sombrero. He is wearing a blue jacket which covers a yellow top, a pair of red long pants with a pink pattern on the right leg, and a pair of cyan shoes.
P2 is female. She is dressed up as a green cactus suit with a blue flower on her head, near the top of the cactus. She also has short green hair.
The background seems to be that of a desert with mountains and cacti. There are also rocks and some desert chili peppers (which are also wearing sombreros) playing various instruments, such as a trumpet, a guitar, and rattles. Tumbleweeds also roll through the desert. During the night scene, a crescent moon can be seen up in the sky.
There are 2 Gold Moves for each coach in this routine, both of which are the same:
Both Gold Moves:
P1: Pose as if you are running with your right arm raised up near your head (almost covered), your left arm a bit far over your chest, and your left foot bent backward at the knee.
Speedy Gonzalez is the second routine that features a dancer dances with no legs, after Ghostbusters (P4).
However, contrary to Ghostbusters’ P4, P2’s legs are simply hidden in the costume rather than removed digitally.
In addition, P2’s pictograms still have legs (contrary to Ghostbusters’ P4’s, which are cropped from the waist down).
In the original snippet from the Gamescom trailer, P1’s legs were normal. However, in the final version, P1’s legs have been edited to make the coach shorter (even being shorter than P2).
This was probably due to Speedy Gonzales being a mouse, and since P1 was supposed to represent Speedy Gonzales, he was made smaller.
This makes Speedy Gonzalez the third routine in which a female dancer is taller than her male counterpart in a Duet, after Careless Whisper and Get Low.
On the World Dance Floor of Just Dance 2017, each chilly pepper from the background appears as a boss, under the names "Muchacharacas", "Muchachopeta" and "Muchachotarra".
P2 can be seen lip-syncing the female vocals ("Lalalala") of the song.
The song title is misspelled as "Speedy Gonzalez".
In the lyrics, however, the name is properly spelled as "Gonzales".
P1’s mustache and hair are brown-reddish instead of black in the menu assets.
This could be a Beta element.
P2’s upper outfit slips a lot, exposing her short green hair.
The Just Dance Now pictograms sprite contains many placeholder pictograms: these are images of the coaches without any in-game edits, and some drawn arrows to finalize the moves.
Speedy Gonzalez’ Zip folder does not contain any Classifiers folder, which generally appears in every other such folder.
There is a glitch when playing with two people: the score bar will glitch and a player will gain stars really fast. The score bar will skip the first two with no sign of them being gained except the names at the top.
The Gold Move pictogram has a red glow instead of a gold one, most likely to differentiate it from the color of the background.
