Pink Lady's Motion Picture (1978)

The Japanese pop music duo Pink Lady are circus performers who show kindness toward a captured "monster," a sad, furry being (played by a man in a bulky, over-sized pink acrylic costume) who suffers acts of unusual cruelty by the keeper and ringmaster before the girls escape with the creature in a circus trailer.

Unfortunately the movie Pink Lady's Motion Picture is not yet available on HBO Max.
