Japanese Animated Flick From Long Ago

There is a scene from a Japanese animation movie I saw, years ago, that vividly sticks in my mind. It was 15 years ago, give or take a few years. I’ve wanted to find this movie for some time now but I have little to go on. Here is what I remember.

Two Armies. Great battle. Bad army alot of mutant type creatures. Setting was fantasy(i.e. swords and kung-fu)

The specific scene I remember goes as such:
Good army sends a messenger to the other side. This messenger was a half bird half man type creature. He gives his message. In the room (IIRC), there are people surrounding cauldron. They put a fish in the cauldron then pull it out. All that is left is bone, still flipping around like a live fish. The next scene shows the bad army throwing the bird man into the cauldron.

OK, I know it’s not much to go on. Being that the scene is so specific, I thought there would be some anime freaks on the boards who could help. Does this ring a bell with anyone? I believe I saw as a part of Kung Fu Theatre and it was a movie, not an animated series.So, If anyone remembers this, let me know. And give me an idea how to get this movie on VHS. Thanks!

This is appropriate for the new Cafe Society forum.

I posted a link to your question here. Maybe they can help figure it out.

Thanks,
I’m hoping it’s not all in my head. This isn’t the first time I’ve remembered a movie that no one else does.
