Early 1960's TV Short-Ever Seen It?

I remember seeing this thing-it seems to have been played a lot.
But I cannot remember what it was called…it was probably no more than 10 minutes long. As best I remember, it was about a little boy, home alone. It starts to rain, and he looks out the window. He sees a floating seed from a milkweed, and imagines the seed turning into a dancer. Sort of like a similar scene in “Fantasia”
That is all I remember-never seen anything like it on YouTube.
