first of all this does prove a side theory of manf=gle being female
ftf(funtimefoxy) is stated in the game as female
mangle looks a lot like ftf
the mangle toy in the girls room from fnaf 4 could be a reference to ftf being mangle or mangle being female or neither
both ftf and mangle r in the ladies night of there game
AND THE LAST BIT OF PROOF NEEDED ingame and there is proof in one of jacksepticeye's videos u will see mangle in ftf enclosure the one time ftf is not there so ftf is mangle
mangle is female cuz as stated ftf is female
