Witch Shrinks Eats And Poops You Out

Im a witch with questionable morality and when you come along my place attempting to sell something door to door I get an idea. See Ive been greedy and you look just right to me. I invite you in and give you a glass of water that Ive mixed some spell powder into. You gulp it up like a stupid, trusting boy and it shrinks you to a bite-sized, cooked meat. I love eating you and discuss all the things I practice as I chew, gulp, digest and eventually poop you out into the toilet. What an adventure for you!
