Agreed- I don't like when Mulan gets classified as a "princess." I love the movie and the character but her father was not a king and she didn't marry a prince...
This is so messed up. Leia is barely even Disney but since she is a princess I guess she can count. Minnie Mouse, Jessie, and Tinkerbell are technically not princesses and if you are going to put them in a quiz and consider them princesses then you must also consider Esmerelda, Alice, Little Bo Peep, Megara, Marie, Melody (who is a princess by birth) Daisy Duck, Claribelle Cow, and Vanellope Von Schweetz (also a princess by birth. I'm sure there's more I just can't think of them all off the top of my head. And why not consider all of them princesses when considering Mulan a princess (she married a general and was not born a princess)
