As you saw Nightmare Mangle on the office, he looked at you. Having an inaudible, loud and static speech. It was very impossible to know what he was saying.. since he's just distorted and glitchy speaking that is completely inaudible, it said... "$̴̺͍̟̦͕͓̿͂͗́͌̎̋̓͆̕͝%̷͓̙͍̰̇̅̈́̓̓̓̊͆̏͋&̵̯̪̈́̃͌͑̊͗́̉/̶̢̺̝͖̯̪̍̂̉́̂̆͜(̸̨͉͖̺̊͌̀̑̾̌/̶̱̰̳͍͉͉͌̽͐̈́́̓̈́̉͘ͅ&̴̮̬̣̒͜ͅ%̷̧͈̻͎͉̱̱͓͛̄̇̀̏̓͛̽͝%̴̛̗̞̭̠̣̯͊&̶̯͙̎̌͊̌̈́͑͝͝͠/̵̢̨̭̮̮̙͓̳̞̈́̏̿̅̀̉̕(̷̲͓̀̒̐̆̔͗" leaving you confused since you did not hear anything and just loud, distortion.
