This is how The Witch Doctor hypnotizes Applejack goes in The Witch Doctor's Revenge.
[The Witch Doctor approaches Applejack]
Applejack: Who are you, partner?
[The Witch Doctor aims his staff at Applejack]
Witch Doctor: You will pay attention for a time. And soon your thoughts shall all be mine. Watch my Skull Staff and you will do as you are told. You are Applejack. And that's a fact.
Witch Doctor: So you will be my slave. Find what I need. And after then will you be freed.
[The Skull Staff glows and Applejack's eyes turn red]
Applejack: Yes. Master.
Witch Doctor: Now find me Quaza.
Applejack: Yes, sir.
[She walks off to do so]
