You could write about:
1.Your ideal name
2.Where you would like to live- maybe Maldonia?
3.Your dream partner (as in boy/girlfriend or husband/wife)- whether they're a Disney prince/princess or a Disney hero/heroine.
4.Dream career
5.Who your Best Disney friend would be
6.Who your worst Disney enemy would be.
7. What you would look like
8. Any super powers or abilities
....etc.- If you want, you can write an explanation why you chose those specific people/things :)
You can add more if you want. You don't have to do this if you don't want to- it's just for fun :)
