I don’t know. She can talk to animals. They do her bidding. You don’t want to be on the wrong side of that should things go south.
Really the question is which princess is the best to date? The Chinese one and the Scottish one from the other studio are both weapons trained. The Persian one has a tiger, the one with the apple has seven diminutive thugs, and the fish girl talks to fish and birds plus her father commands the sea. The one that slept has three magic wielding aunts. The island one knows a Demi-God. Don’t even consider the princess with the ice powers.
I guess your safest bets are the woman with the hair, the one who became a frog, and the one that loved books.
