- The scene discussing everyone's reaction to Elphaba post-melt down doesn't give much detail, only that it was horrifying, vomit inducing, and that they aren't going back into that room to clean it up any time soon.
- The bizarre inter species orgy in the philosophy club turns from crude to eerie as the host narrates cryptic prophecies along this.
- One of Elphaba's first words was after being found outside in the darkness, "horrors."
- Ilianora/Nor being "stitched into a finalizing virginity" so that she would never have children who would suffer as she did.
- The Wizard's mechanical head contraption. It was deliberately meant to be creepy and loud.
The Wizard's head contraption: I am OZ!!! THE GREAT AND TERRIBLE!!!!!
- The score calls for tone clusters in the low octaves of the piano, traditionally played with a flat palm or even a fist slammed down at random in the indicated area. The effect, especially at the immense volumes indicated, is deeply unsettling.
- The Reveal that Elphaba turned Boq into the Tin Man (so he could live despite lacking a heart) looks like something out of a horror movie. The music, along with Boq going mad from the revelation, really cements the mood.
- "March of the Witch Hunters". The chorus part is a frenetic Dark Reprise of "No Good Deed", turning Elphaba's own music against her. Tin Man!Boq briefly teeters on the edge of psychotic, then leaps straight into it just before they start to sing. Madame Morrible is in full flight, certain of victory, and genuinely terrifying in a way we haven't seen before. Completing the picture, the ensemble have loud, high-register harmonies under the melody line, creating a 'wailing', 'howling', very primal and aggressive effect.
- An example of Fridge Horror: After "As Long As You're Mine," that screaming sound Elphaba hears before she sees the house... Is that supposed to be Nessarose as she's dying? Either way, it's chilling.
- The scene in which Elphaba is tricked into giving Chistery wings. The transformation is played for all the horror it's worth, and then it gets ramped Up to Eleven when a set of curtains open to reveal an entire cage full of monkeys that Elphaba has just forcibly, accidentally and irreversibly transformed.
- Dr. Dillamond losing his voice. We never get any details as to what actually happened, and just the idea that the goat equivalent of a successful, middle-aged man could give up something so important is really quite chilling. When you stop to consider the implications of whether or not he can actually REMEMBER being a sentient creature…things get even worse.
- Nessa taking away the Munchkin's rights just so that she can keep Boq with her. That's one horrific ruler to live under.
