Spineticklers

Spineticklers is a series of books that appear in Diary of a Wimpy Kid: Double Down. It has been read by Greg Heffley and other kids at his school. The author of the book is I.M. Spooky, and there has been at least 97 known books in the franchise, despite the fact I.M. Spooky has written almost 200 books. There is a "Junior" series, which is less scary and is intended for little kids, but those books are read by Rowley Jefferson because he is too scared to read the regular/original series. Although, he is still very scared of the "Junior" books, he wrote a letter to I.M. Spooky about how he wanted the latter to make the books way less scary.

It is based on Spine Tinglers by M.T. Coffin.
