Very old horror movie where this witch is trying to make this little boy a sandwich for some reason and then at the end of the movie a baseball rolls up through his bedroom door and says something like "your mother tastes delicious" and he runs down stairs to the kitchen and see here stomach being eating by these little midget monsters. ****ing weird but it's been bothering me. Any help?

That would the infamously bad movie:
