Five Nights At Freddys 1, 2 and 3 Characters Guide!

Mangle

Mangle begins the night in a corner at Kid's Cove, in a contorted heap of machinery. Once activated, it will mainly travel the pizzeria via the ceiling. However, in some rooms, it may be seen traveling via either wall or floor, almost appearing to spectate the area. It travels through the Prize Corner, Game Area, Main Hall, the hallway outside The Office, then Party Room 1, and then Party Room 2, before finally crawling through the Right Air Vent to reach The Office.
Mangle does not try to enter The Office from the hallway. It may also frequently appear in the same room with other animatronics. When it moves in or out of a room that is monitored by the cameras, a static feed will occur. Mangle will generally only enter The Office when another animatronic is currently in there, thus making both the animatronic in The Office and Mangle easier to fend off.

Mangle is an incredibly active animatronic, as it can leave Kid's Cove at 12 AM on Night 2, and arrive at the hallway within the hour. It is not important to watch it, as its radio frequency sounds can be heard when it is in the vent. Once Mangle is spotted in the Right Air Vent's blind spot, the player must put on the Freddy Fazbear Head to ward it off. If the player brings up and then lowers the Monitor before putting the Head on, Mangle will be on the ceiling above the player.
At this point, Mangle may randomly attack, where its head swings down from the ceiling towards the player's face. It appears it cannot be made to leave once inside The Office, besides waiting until 6 AM, which makes surviving the night nearly impossible; bringing up the Monitor will trigger Mangle's attack once lowered again, but the player will need to use it to wind the Music Box, lest The Puppet come after them. On early nights, however, Mangle may not attack when the Monitor is raised.

Whenever the player sees Mangle, it will make a distorted, garbled sound, akin to radio static. The sound is actually possibly an amateur radio band, with a military-encoded RTTY-75W (Radio Teletype 75 baud WIDE) transmission. In the middle, there is what sounds like a demonic voice, but it is actually only mistuned SSB (Single Side Band) voice. Contrary to popular belief, RTTY is not morse code, the voices do not have a meaning, and RTTY is not SSTV either. The sound is only for aesthetic purposes - hard to decode, but only there for environmental purposes.
