De acordo com Stine ele mesmo , ele não usou um ghostwriter para a maior parte dos romances de Goosebumps.
Stine has written 250 books, and he is contracted to write one Fear Street romance and one Goosebumps story a month, and a Ghost of Fear Street every other month for the next three years. Largely because of Stine’s popularity, Scholastic Incorporated experienced a 60 percent jump in sales from 1993 to 1994, making Scholastic the fifth largest children’s publisher. As Stine himself proudly admits, "I’m a machine. I’m cut out for this. I’m usually at the computer by nine in the morning. Generally I say that I’m going to write twenty pages. I don’t finish until I’ve done my twenty pages—and that’s how I get so many books done." Although Stine spends two to three days outlining his books, once that task is finished he claims, "It takes me ten days to write a Fear Street book, eight days for a Goosebumps." Stine works without an assistant or a "ghost writer," but his wife Jane Waldhom does act as editor.
Ele também confirmou isso em um Reddit AMA de 2013:
Q. I rather enjoyed Goosebumps as a kid. The Monster Blood books, specifically. Did you write all of the GooseBumps books yourself, or like K.A. Applegate, act as more of a supervisor to other ghost writers?
RL__Stine: I wrote all the GB books myself, believe it or not. Sometimes I had writers help me with the outlines. But all books were by me.
Claro, isso não leva em conta que ele pode estar mentindo.
