Watch: Girls' Generation's Sunny And Kim Heechul Have A Dance Off To HyunA's "Change"

The cast members of “Ask Us Anything” challenged the members of Girls’ Generation on their knowledge of popular K-pop dance songs.

After the production staff plays the first second of a song, each team must guess which song it is and dance to it. Seohyun correctly guessed the first song as KARA’s “Mister,” which was followed by a Girls’ Generation cover of the famous butt dance.

Kim Heechul then correctly guessed the next song as HyunA’s “Change”.

Watch the dance off between Sunny and Kim Heechul below! Who do you think nailed the “Change” dance?
