I don't really have a favorite group of characters so I really have nothing to answer about that.
I do classify my favorite characters by overall group. SO, here goes.
Stitch is my favorite animated character. He is so funny, goofy, and mischievous, yet sweet and loving. I find him to be so darling and I LOVE his little voice!
Mary Poppins has been my all-time favorite character since I was a little girl and saw the movie the first time. I adore Julie Andrews and she brought the magic of Mary Poppins alive for me. I still find the character to be just as magical today as she was the first time I saw her slide UP the bannister.
Ariel is my favorite princess. This was the first new Disney movie to come out in the theatre when I was a child. I was 12 and I LOVED it. I saw it three times in the theatre and then wore out my VHS tape of it. When I was 14, I was a youth player at our local city theatre and Jodi Benson (the voice of Ariel) came through on a touring version of "Chess". I had the opportunity to meet her, talk with her about the movie and act with her in the play. It was incredible.
Great idea, MLP!
