Who is a literary "manic pixie dreamgirl"?

I'm planning an English lesson/unit. I just listened to a podcast by howstuffworks.com called Stuff Mom Never Told You. The hosts chatted about a type of female character called a "manic pixie dreamgirl," and they cited some articles that discuss this personality/style. I'd like to use the podcast and the articles in a lesson. The character examples that I'll begin with are Zooey Deschanel's character Jess in the TV show New Girl and Amelie from a 2001 French film of the same name since these are spot-on examples of the kind of female character the podscasters describe as "manic -pixie dreamgirl." The character is quirky, cute, loves doing nice things for others, isn't defined by the friends she has, is often not aware of how her quirkiness is seen by others, sometimes "lives in her own little world," can be a bit naive, etc.

My idea is to spark interest using clips from Amelie and New Girl, then move to literature. I can use Stargirl by Jerry Spinelli, but that's Adolescent Literature. What would be the next step? What character might I use for students who want a bigger challenge than Stargirl? Have any novel or short story ideas?
