How can I audition for My Babysitter's A Vampire on Disney Channel?

I know the main characters are casted, but how can I audition to be an extra or something. I swear I am NOT doing it for the money or fame. I don't have an agent and don't intend on getting one anytime soon. I have these fangs in my mouth (they're really weird) and thought i might be useful. This is a way to be helpful and lie my lifelong dream
