This is just for fun. I enjoy these characters and it's only a joke!
Ariel- You have to change species in order to find the man of your dreams, even if he loves an evil sea witch, then, when you get married (at age 16), get pregnant as soon as you can and surprise your whole family by coming back from your honeymoon with a baby (at age 17)!
Giselle- Trusting an old hag to grant you a wish won't do you any harm, then, ask a stranger to let you sleep in his house! Oh, and make sure to infest his house with squirrels.
Belle- Even if your boyfriend locks you in his house, then pushes you to the ground, it means he loves you!
Esmeralda- It won't hurt anyone's feelings if you decide to kiss an injured soldier right in front of the sweet guy who would die for you.
