His M.O. was to give those music boxes to the women he was trying to seduce.
He gave them each a music box. He spent the night with each woman. I don’t think they could be more frank in a movie directed at children.
Both women appeared to be post coital euphoric and deeply in love with the guy.
That was my take-away. You and another person disagree, and you may be right.
He didnt give a “music Box “ to the older witch,she created it with her magic to fool her younger sister,,watch the movie again.
