Who do Ты think is the most introverted and extroverted princess?

Introvert: Mulan. She's trying to find out who she is, but when she's attacked, she'll process the information thoroughly, and she'll make sure her answer is right. She's not highly flamboyant, but she'll bloom like a blossom and you'll see the good side of her.

Extrovert: Ariel. She's not smart, but she's ready for anything. If she fails to be completely smart at a level, then she'll learn throughout the way. Her intelligence is average, but she learns something correctly by doing it wrong, and she gets better each time.

Introvert: Aurora или Mulan. Both display characteristics of dominant introversion.

Extrovert: Snow white или Ariel. Both display heavy extroversion.

Lame answer is lame.

Introverted- Belle или Mulan
Extroverted-Ariel
