i was digging through the sister location game files and found what looks like a funtime chica jumpscare, but the weird thing is it uses the minireenas’ jumpscare sound. so my theory is that funtime chica was originally supposed to be in sister location but got scrapped. the sound that we now know as the minireenas’ might’ve actually been hers at first, but they reused it to save time or something. it kinda makes sense since funtime chica didn’t show up until later in the series, even though most of the other funtimes were already there. it’s not confirmed or anything, but it’s a pretty interesting find and makes you wonder what else was cut from the game.
