The FNAF Survival Logbook is meant to look like an activity and/or guidebook for Fazbear Entertainment security guards to fill out during their first week on the job. However, the book already has red pen entries from a security guard named Mike, who appears to be the same Michael Afton from Sister Location based on his notes and sketches. As such, some fans believe the Logbook could prove that Mike Schmidt and Michael Afton are the same person.
