Mind Manuals

The Mind Manuals are a series of books that are kept on shelves behind the main console in Headquarters. They contain information about how Riley's mind operates including a map of Long Term Memory. Joy offered them as a way to distract Sadness and make her stay in the Circle of Sadness on Riley's first day of school. The information Sadness gleans from them later proves to be beneficial when she and Joy are trying to get back to Headquarters.
