Ariel we saw in the prequel though. I would've liked to see Belle's mother because I just wonder what happened to her...How she met her father and how Belle was born despite her father being kind of a goofball. It would be interesting to have he mother be like her... judging from the heart not looks or popularity.

If only to see her comment on the events that occur during the movie. Also the film suggests Belle moved recently into town, but they never explained why...That could've been nice to know.

Also Pocahontas' mom. I don't mind not seeing the others since it works better for their stories for the mom to be out of the picture.

i'd like to see Belle's mom to know how Belle is like around a family and also Jasmine's mother.

Really, all of them but especially Cinderella and Pocahontas as well.

I chose Jasmine though because that line from the Sultan referencing Jasmine in relation to her mother has always intrigued me greatly:
"I don't know where she gets it from. Her mother wasn't nearly so difficult." (or something to that effect)

It would have been nice to see a scene of her and Belle reading or something during the beginning. Same with Snow White.
