I thought of another idea for this fanfic. Some of the characters will have certain personality traits for their specific songs, or they will act like some of the previous Idol contestants.
For example, Cera would fit the persona of Kelly Clarkson, Chomper would act as Chris Daughtry, and just for kicks, Petrie would be Sanjaya Malakar
These are not final, but this is just to give you an idea of what I might do.
