Desperately seeking to be popular again, Mary Cherry fails in an audition to a teen talent show. But that didn't stop her, and she decides to put a team of students together to be in ""The Big Head Challenge"". Everybody is studying for the SATs and they all think it would be a nice way to test their knowledge at this competition. Cherry Cherry, who has become a student at KH (trying to beat her 50 points score in her SAT), also tries to get in, but loses the very last spot to Josh, who surprisingly know a lot more about chicken than we thought. Meanwhile, Carmen decides to take salsa lessons, and has her heart broken by the instructor, whom she had a crush for. But after he realizes how bad he made Carmen feel, he goes to KH to ask her out. At the competition, the gang is first relieved to be against the John Ashcroft Private School for Special Needs Children, but then surprised when they see that Cherry Cherry has bought the entire team and replaced the students by the teen talent show
