I don’t know that much details about this movie because I can BARELY remember it. It was a cartoon, there was a old woman that was evil i think she was in red.. she had huge saggy boobs with cleavage and there was a scene where she sang and dramatically wiped her nose with her index finger, which my sister and myself found hilarious when we were younger, I’d LOVE to find this movie, all i know it that it’s quite old..
Sounds like The Rescuers (1977).
