The four MAMAMOO members covered Lee Moon Sae's "Flying, Deep into the Night", and as expected, they didn't disappoint with their powerful vocals, dance, and stage manners for their colorful rendition. Fellow competitor Davichi's Kang Min Kyung�commented, "It was so cute and powerful. They said they were 21 years old, but suddenly, adults came out. They're so cool," and Lee Hae Ri�also praised, "It's a feel that can't come out at that age."

Though MAMAMOO did manage to defeat their sunbaes�S�(Kangta, Lee Ji Hoon), it was Yoon Min Soo�who took the final win.
