In my opinion, they do not only reveal what will happen, but also manipulate events. When Macbeth approached the witches, they could have concealed the truth from him and just let the events unfold, but they didn't do it. They told him about the prophecy, thus initiating the events that soon followed. If they hadn't told him the truth, Macbeth might have never killed Banquo, Duncan, and the rest in order to become king. So yes, they manipulated events and caused a great tragedy.
Does this count? Lol sorry
This dosnt make any sence do you have More?
Answer:
I have one. "Barbie's Literal Dream House"
Explanation:
You said they turn into dolls so that explains the Barbie part. Also, Barbie is often associated with "Barbie's Dream House" but since it's a sleepover it's literally a dream house. Don't publish a real novel with that title though because you could get sued.
