(The Witch is pacing, muttering to herself, a small, black cat perched on her shoulder.)
"Humph. That blasted girl. Sneaking around, stealing my precious broomstick! As if she doesn't realize what power it holds! Power to control the very wind, to soar through the skies, to... to... [She stops pacing, her voice dropping to a low growl.] To crush those who dare defy me! And she, she thinks she's clever, hiding behind the Yellow Brick Road! She thinks she's safe, that she can escape my wrath! But I'm coming for her, little Dorothy. I'll tear down her precious road, brick by brick, and then... then she'll know the true meaning of fear! [She pauses, her eyes flashing with cold fury.] She'll know the power of the Wicked Witch of the West!"
(The Witch throws her head back and cackles. The cat shivers and buries its head in her hair. She turns, her eyes burning with a fierce intensity.)
"She'll wish she'd never set foot in Oz. She'll wish she'd never crossed me! She'll wish... [She trails off, a chilling smile spreading across her face.] She'll wish she was dead!"
Notes:
* Focus on the Wicked Witch's power and rage: Use a strong, commanding voice to emphasize her authority and anger.
* Highlight her intelligence and cunning: Let the Witch be sly and manipulative, even in her rage.
* Show her vulnerability: The Witch is not just a force of evil. She is also a being driven by fear and a thirst for power.
* Be playful and have fun: The Witch can be a fun and complex character to portray. Don't be afraid to experiment with different tones and emotions.
Remember to adjust the monologue to fit your specific interpretation of the character and the needs of the production.
