I don’t remember exactly when I saw it but it was probably some time in the 90’s when I was a little kid. It was an animated short (I think in color) and I don’t remember it having any dialog but instead just had sound effects and music.
I don’t remember the plot but I do remember it had to do with a guy being stranded on a desert island and about him dancing to music. Somewhere a long the way a skeleton shows up and they dance together. That’s all I remember unfortunately. For some reason it stuck with me all these years and I’d love to find it again just for curiosity’s sake.
