PLEASE HELP! What is the name of this movie?

I used to watch it when i was like 5 or 4 and now im 14 so that was about 10 years ago. All i remember was it was cartoon and there was a girl with black long hair, and she wore a red dress. And she was in a castle. I dont remember much except that there were 2 baTs i think one was red and the other was purple. And all i know was she was asleep and her prince came at one point i think.. I was almost positive it was another version of snow white but i couldnt find it on the internet PLEASE HELP!
