JYP Entertainment’s new boy group Stray Kids has released an entertaining new dance practice video for “Mirror“!

In the new video, the nine members of Stray Kids take on the random speed challenge while performing the choreography for their song “Mirror.” Although they initially attempt to maintain their composure, the members eventually can’t help cracking up as they struggle to keep up with the song’s changing speed.

Even as Stray Kids amusingly slow down and speed up their dancing, they still manage to showcase their impressive synchronization and the cool moves of their latest choreography.
