Hi everyone. I saw this movie when I was about 6 or 7 sometime around 1987 or ’86 ,it looked like anime. From what I vaguely remember it was about a kid not sure if it was a boy or girl traveling with a little horse that was either wood or robotic and it hovered or floated? The movie looked dark and somewhat bleak I believe black and white and they were followed by these big blocky robot like creatures who seemed like they were in a trance marching. There was also an old witch/lady who turns people into wood creatures and in the end she turns into a wooden doll. The world they lived in was idk I guess sort of post apocolyptic. It’s not Unico or The Last Unicorn. I have been searching everywhere for this movie and cannot find it if anyone can help I would greatly appreciate it!
