I'd be a cartoonist who makes a Flash animation series and puts it online. I don't know if I would get along with the main characters though. I could team up with them to do some online comedy collaboration, or I could end up as an antagonist/rival character trying to get more viewers than them or something.
But as a cartoonist, I would most likely have the "crazy artist" personality, and seeing as that position has already been filled by Spencer I think the writers would reject my character! XD
I would be a friend of Carly, Sam and Freddie. I would be popular with fashionable clothes and buy fashionable clothes for Carly, Sam and Freddie. We could be the popular gang of Ridgeway School.
