Each of them ship themselves with a male character on Total Drama; Ash ships herself with Tyler, Lizzy ships herself with Duncan, Katie ships herself with Mike, and Yazzy ships herself with Trent.
This is interesting considering the following guys are in favorites for the individual girl the get shipped with.
They are considered to be the four main characters from Pretty Little Liars; Ash is Aria, Lizzy is Hanna, Katie is Spencer, and Yazzy is Emily. Coincidently, each Liar that they're compared to also happen to be their favorites on the show.
They are all fans of the Total Drama franchise.
They enjoy making TD edits.
They are all friends with Xavier.
Lizzy is the only one out of the 4 that doesn't show interest in One Tree Hill, Glee or other teen dramas and prefers Teenick.
