Duh.

Easiest question ever.  I would be the Little Mermaid, otherwise known as Ariel.  She is my favorite Disney princess, and should be yours too! Reasons why I would want to be Ariel:

1. She lives in the ocean.  Coolest home ever.
2. She is a princess and a mermaid.  That is basically, like, the best combination ever.
3. She is the baby of her family.  This would be a change for me because I am the oldest.
4. She has an awesome voice.
5. Her best friends are really cute sea creatures.
6. She has most amazing hair ever.  I wish I had hair like that.
7. She saves her handsome prince, Eric - not the other way around.  And they end up together, even though Ursula stole her voice and she can not actually talk to him.

If I could not be Ariel, then I think I would have to be Blossom from the Powerpuff Girls.  She is another strong ginger woman, and she can save the world before bedtime.
