Goosebumps Holiday Collector's Caps Book with 16 Glow-in-the-Dark Cool Caps and a Heavy Duty Santa Curly Slammer

Goosebumps Collector's Caps were promotional books released to accompany Goosebumps "caps" which were POG-like milk-caps. Each cap features art from the covers of Goosebumps books. The books also contained various games and activities, such as cross word puzzles, word searches, fill-in-the-blanks, quizzes, matching, and pages letting you "write your own scary story." Both books provide new facts on several Goosebumps books, such as the backstory of the ghost in Jerry's house in Piano Lessons Can Be Murder and the backstory of the man who created The Haunted Mask. In the second book it was revealed The Horror at Camp Jellyjam was originally going to titled "Smelly Summer". Both books were also sold along with a Curly the Skeleton "Slammer." Although the books are credited to R.L. Stine on the cover, Stine is addressed in third-person throughout the books.
