Girls' Generation made a successful transformation into the Wonder Girls.

On a recent filming session of JTBC's 'Girls' Generation & Dangerous Teens', the girls headed over to karaoke along with their mentees.

The members took the boys out for night on the town, as they have been good about keeping the 'commandments' within their dormitory. The first stop was at karaoke. The girls showed the boys how to let loose and have a good time, they also performed the Wonder Girls' "Be My Baby" and perfectly emulated their dance.

Girls' Generation also performed their own song "The Boys", singing and dancing without stopping for a break. They relieved a lot of stress and enjoyed a fun night with their mentees.

However, something occurs on their second stop of the night, and some of the boys leave without enjoying the rest of the night with their mentors.

The episode is scheduled to air on January 15th at 7:30 PM.
