The Puppeteer is an all-new character introduced in FNaC 3. He is one of the actors at "The Rat and Cat Theater".
He can only be found on the Night 3 and Night 5 post-night cutscenes. In Mary's Dreamworld, he is represented by Monster Vinnie.
The Puppeteer has makeup and clothes in a similar style to that of Vinnie the Puppet.
He is said to be the one who controls Vinnie on-stage, either by string or by inner-hand movement.
The Puppeteer is revealed to be the killer of the entertainers wearing the Rat and The Cat's suits, depicted during the fifth night of FNaC 3. The Puppeteer inadvertently kills the Rat Actor after an altercation regarding the employee's drunkenness at work. Grappling, the employee manages to break free, only to hit his head on the table holding Vinnie the Puppet. Afterwards, the Cat's Actor enters the room, discovers the body, and threatens to call the police. The Puppeteer then kills the Cat Actor to ensure that his crime will go unnoticed. The Puppeteer lies to the police, puts his entertainer diploma away, and leaves. Unbeknownst to everyone else, the entire incident is overheard by Mary Schmidt.
- The incident that unfolds on Night 5, involving the Puppeteer and the other mascots, was alluded to in various newspaper articles found in the Deepscape of Night 5. These newspaper clippings, however, depict the incident as the Puppeteer told the police, not what actually happened.
