since you know about rock and rule maybe you can help me find the name of another animated movie around this time.

this movie was in black and white, had still photos for backgrounds and the villain had a bunch of buzzards and he was always farting. It was hilarious at the time and we loved to watch it because they cussed a few times and that wasn't normal for animated films in the mid 80's.

Found it.

Twice Upon a Time. http://www.imdb.com/title/tt0086489/

I thought it was in black and white but I think it was only certain parts of the movie.
