Trivia

 * This is heavily considered to have some "ghoulish" features.
 * Just Dance always has a Halloween themed dance because the game comes out in October. This is most likely the song for Just Dance 2015.
 * It is the second Lady Gaga song to have this Halloween theme, after Applause.
 * The words "stick" and "b***h" is censored, the former referring to a man's reproductive organs and the latter simply being too explicit. This is the first Lady Gaga song with censored words.
 * This is the third Lady Gaga song in the series, with the first two being Just Dance and Applause on Just Dance 2014
 * This dance resembles Black Widow.
 * This is the first time that the dancers are completely white, as well as hardly visible.
 * This is also the first time the coaches' skin color isn't tan/yellow like in Hot n Cold because they're wearing white clothes.
 * This is the second song after Hot N Cold in which its dancer(s) are wearing wedding gowns.
 * It is the first time a dancer changes her real-neon contrast to real. It always happens in Just Dance Kids but it has never happened in the original series.
 * If anyone would be able to see the lead dancer's face clearly, they would assume that she might be the same dancer as P4 from Tetris.
 * This routine (especially the extreme) uses some of the official choreography for the song with slight changes for the choreography when the chorus is sung. Both modes have similar moves due to them following the original choreography.
 * The lead dancer does not keep in rhythm with the background dancers during the twists.
 * This is the oldest 21st century song in the game.
 * The backup dancers highly resemble Maddie Ziegler in the music video for Chandelier by Sia when the verses are sung.
 * Since Oh No! has non playable backup dancers, this is the official first ever all female Trio dance mode in the whole series, not counting the On-Stage version of Just Dance, which might be the same dancers.
 * It's the only classic all female trio in Just Dance 2015.
 * The game uses the longer version, which is 4:54, rather than the shorter version like Ubisoft usually would use. This is one of the longest songs in the main series.
