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