FIRST OF ALL I KNOW! I KNOW ALREADY! FREDBEAR DID THE BITE OF 87! (For the people who believe this theory for I believe it was the Bite of 83).
The Diary of Mangle
Chapter 1: 2 Days Before the bite
Dear Diary... I had another terrible day... Im tired of being taken apart and put back together again and again and im being driven to insanity...
now instead of being Funtime Foxy I have to put up with "Mangle". At least Foxy isn't like the others... I don't want my boyfriend to joke
about me... that would be devastating... but the others do... and now another vixen might have to share my fate... they have a Funtime Foxy at
our Sister Location now... and a Funtime Freddy... but here, HERE, I'm going insane... I can't take it anymore... its only an amount of time before I snap...
Dear Diary... I can't take it anymore... even Foxy calls me Mangle... I feel betrayed... and sick... you are now the only best friend I have... my servos are twitching and my eyes are flickering... I'm going insane, I'm sad and angry... I wanna scrap myself and finish this... I'm done...I'm done... I want this to end... I look like Withered Bonnie's new face... I now keep to myself in Kid's Cove... I don't even visit that Nightguard anymore... and I never missed out... IM SICK OF MY LIFE AND I CAN'T HANDLE THIS *This part is covered by her tears of oil, good thing too... Mangle's got a quite vulgar vocabulary at night*
