The Cos Fam's audition was never shown. It is unknown whether or not it was buzzed, but at least two judges voted "Yes," sending it to the Vegas Round.
The Cos Fam was one of the Standby Acts in the Vegas Round. It was sorted into the "Kid Acts" category. Its performance in Episode 713 consisted of dancing as a trio to “Get Up Offa That Thing” and “Disco Inferno”. Its audition was not strong enough for the judges to send it to the Quarterfinals, eliminating it from the competition along with Alex Lund Lil Babywockee, Tevin McGuire, and The Williams Bruthuz.
