Misty Marina has more youthful ears. So, some could tease her, or say to her that she is still ‘fluffy’ behind her ears, telling her she is a youngling. She wants to be seen as mature, so it would definitely be something she didn’t like to hear.
At least that was a possible character trait for her. ^^ She is more adventurous in any case. Kinda like the parrot pirates and she could end up on the wrong side of the law.
