The Phantom Puppet is a boss in Slender Fortress.
The Phantom Puppet appears much like its Five Nights at Freddy's 2incarnation, though its body is charred and its eyes have small white irises, much like the other phantoms. Its charred and burnt appearance possibly foreshadows the torching of the attraction. Its three buttons are very dark in color. The Phantom Puppet appears very briefly in CAM 08 and then appears in The Office depending on whether or not the player changes the Monitor's view before lowering it.
In Slender Fortress Edit
The Phantom Puppet cannot instakill you but it makes your screen flashing red and makes you blink faster, a few Phantom Animatronics has the only helper that CAN instakill you called, Springtrap.
