However if I recalled the Princess in the Princess and the Frog Grimm version did not want a prince however simply wanted her beloved prize golden ball which she she made pact with the Frog to obtain it for her.
Yup, she made a deal with a frog to fetch her golden ball out of a pond on the condition that she let him eat off her plate and sleep on her pillow. After she got the ball back, she blew him off. Eventually she let him eat off her plate and sleep on her pillow for 3 nights, and that broke his curse and turned him back into a Prince.
So they took the thing of her being a Princess, and the association with a single golden valuable object, and used that as part of the show’s version.
