Odd subject - SPOILER ALERT SPOILER ALERT
It occurs to me after watching this movie that the subject matter is very adult.
You have a naive girl who longs for romance and adventure in Paris. She runs away from her stable home and in the process is swept up by a smooth talking thug who convinces her to let his "sister", another criminal who looks an awful lot like the madam of a brothel, spruce her up to look like a french tart and then attempts to sell her to an American for "marriage".
Where I come from we call that sex trafficking.
Despite the fact that everything turns out in fairy tale fashion with a heroic rescue, the poor naive girl is still in terrific danger and nearly ends up in a foreign country, the property of another and without resources.
Despite the Warner Brothers technicolor animation - still an odd subject for a kids movie I think, lol.
