This is how The Witch Doctor tries to hypnotize Starlight and Trixie goes in The Witch Doctor's Revenge.
[Starlight and Trixie are walking when the Witch Doctor appears and aims his staff at them]
Witch Doctor: Watch my Skull Staff and you both shall do as you are told.
Starlight Glimmer: Now, Trixie!
Trixie Lulamoon: Okay.
[Starlight and Trixie use mirrors to reflect the staff's affects]
Witch Doctor: You both are strong. You both are powerful. You will have to do as I say. Watch my Skull Staff. Be my slaves and do as you are told.
[But they ignore him]
