- Dr. Two-Brains' appearance: personally, this troper isn't afraid of him, but imagine being a little kid seeing a mad scientist with red eyes and a tiny brain sticking out from his head!
- In the episode Victoria Best, when Victoria lost a trophy to Becky Botsford for vocabulary, her parents are disappointed and tell her to keep her eyes on the prize. Their eyes start to grow red, and so does Victoria's. Becky herself is visibly scared when Victoria was staring at her with red glowing eyes, and was remaining silent.
- Miss Power is a terrifyingly realistic embodiment of bullying of the verbal variety, the kind that everyone claims is harmless but isn't. And to make matters worse, she got WordGirl doing it too. *shudder* She also attempts to fry Dr. Two-Brains with her heat vision.
- In Lunch Lady Chuck, Chuck puts on a hairnet that is too tight and it compresses the entire top of his head. Where is his brain? He goes to the dentist in one episode—what are his teeth attached to? Are they floating around inside the bread? Word of God says Chuck's head is a sandwich and the rest of his body is a human's body, so one has to wonder how he's able to blush, cry, get a cold, etc.
- Additionally, if he is a sandwich, is him eating sandwiches some sort of cannibalism? He makes a sandwich shaped like WordGirl and asks it how brave she'll be in his belly— just creepy overall.
Nightmare Fuel / WordGirl
Surprisingly enough, not even a kid's show like WordGirl is immune to Nightmare Fuel.
