It would be like the Outfit/Hair Style countdown you guys are running now... I think it would be interesting, maybe even more than these because characters are easier to argue about than clothes and hair. I think these should be the candidates (total=49). If you think I forgot someone or that any of these shouldn't be in the list, tell me (I'll wait a day before I start it, if you guys are against, I won't do it)
SNOW WHITE --> Grumpy, Happy, Dopey, Sleepy, Sneezy, Doc, Bashful, Animals
CINDERELLA --> Jaq, Gus, Bruno, Fairy Godmother, Horse
AURORA --> Flora, Fauna, Merryweather, Animals (Sleeping Beauty), Samson
ARIEL --> Sebastian, Flounder, Scuttle, Animals, Max
BELLE --> Horloge, Lumiere, Madame Samovare, Chip, Philippe
JASMINE --> Abu, Carpet, Genie, Rajah
POCAHONTAS --> Meeko, Flit, Nakoma
MULAN --> Mushu, Gri-Li, Yao, Ling, Chien Po, Little Brother, Kahn
TIANA --> Ray, Louis, Charlotte, Mama Odie
RAPUNZEL --> Pascal, Maximus, Thugs

Perhaps you should add the horses - the one of the prince, Cinderella's, naturally Samson, Phillipe and Kahn.

Are you sure about Snow White's one? I mean, we really don't get to know him... The others I already included, thanks =D
