Minah made a dolphine sound.

Girl's Day Minah showed off her dolphine-like vocals on December 18ths episode of SBS 'Challenge 1000songs'

On this day during the preliminaries Minah chose the song 'Oppa' by Wax. MC Whee Jae worried "This song is difficult" but Minah succeded with her solid vocals.

Especially during the part "You can have me now" where Waxs' technique is used, Minah purposely went off pitch during the 'have' part.

To which MCs commented "it was a purposeful off pitch. Dolphine sound came out", complimenting. To Girl's Day's performance Byun Woo Min showed off a dad-like smile.

On the other hand, on this day's 'challenge 1000 songs' Lee Young Ha, Yoon Jung Soo, Girl's Day(Minah Sojin), Whee Il Chung, Jo Gap Kyung, and other appeared to compete for the golden key.
