Differences from the book
- In the book, Mr. Mortman keeps pet turtles, but in the episode, he keeps pet spiders.
- Unlike the book which ended with Mr. Mortman being eaten by Mr. and Mrs. Dark's monster forms, the ending is extended where Mr. and Mrs. Dark explain that Mr. Mortman is the first monster to come into their town in 20 years besides them where they don't want their children to tell anybody else. When Aaron appears with a monster mask and later takes it off when Mr. and Mrs. Dark had brought out their fangs, he asks what is for dessert. Mr. Dark then answers with, "You....like Cherry Pie?" and the family laughs. Lucy and Randy are never seen as monsters.
"The Girl Who Cried Monster" was released on DVD on September 16, 2008, as the fourth episode on Monster Blood. It was included in a 3-Pack Thriller DVD on August 26, 2014.
