Okay this one is for a friend. So I can not provide any more details than what he gave me

Short cartoon in the 70s-early 80’s.   2 animated black kids (sisters) get scared of something (Maybe a storm) and hide in a closet, so all you see is their eye balls floating about in the dark. They talk about this and that.  The one part of the dialogue goes this way:

Little sister: I wanna piece of candy

Big sister: We don’t have any candy

Little sister: I wanna piece of candy

Big sister: We don’t have any candy

Little sister: I’ll sing….LALALALALA

Big sister: Here, Here is a piece of candy

Any idea what this short feature was?
