Five Nights At Freddy's - Killer Freak Show

"Right now, we have two specially designed suits that double as both animatronics and suits."
"Do not touch the spring locks at any time. Do not breathe on the spring locks, as moisture may loosen them, and cause them to break loose. In the case of the spring-locks come loose while you are wearing the suit, please try to maneuver away from populated areas before bleeding out, as to not ruin the customers' experience."
"Management has also been made aware that the Spring Bonnie animatronic has been noticeably moved."
"As always, remember to smile; you are the face of Freddy Fazbear's Pizza."
"Someone used one of the suits. We had a spare in the back, a yellow one, someone used it... now none of them are acting right."
"We found one. A REAL one."
"I always come back..."
It's always in the character of a killer to return to the scene of the crime. In the case of William Afton, however, his attempt to reanimate the power of remnant infused metal ends with disaster as his old murder suit crushes him to death.
Yet 30 years later, the killer known only as the Purple Guy returns, this time with a dirty, golden secret, and as the mascot of the horror themed Fazbear Fright.
