They Call Me the Night Howler! is the eleventh book in the Goosebumps SlappyWorld series. It is currently slated for a release in 2020. [1]

The cover artwork depicts a pair of purple gloves reaching out from a dark area surrounded by purple curtains, as a pair of large orange eyes look on from the shadows.


During an interview, Stine revealed some details of this book's plot: "...a boy is at a superhero museum, and he runs into this superhero. And the superhero says "I'm sick of this. I don't want to do this anymore." And he gives his costume to the boy, and the boy becomes The Night Howler."[2]


  • The title of this book is a possible reference to They Call Me Creature and The Howler, two books from the The Nightmare Room series, which were also written by R. L. Stine.
    • Additionally, the concept of a kid unwillingly becoming a superhero is similar to Shadow Girl.
  • According to Stine's editor, Susan Lurie, Dr. Maniac makes an appearance in this book.[3]
