Sister Location is a new to be Five Nights at Freddy's game. The game will supposedly be arriving on October 7th, 2016(but it's Scott Cawthon, so the date may be a load of bullcrap.) with the new animatronics Baby, Ballora, Bidybab, Ennard, Funtime Foxy, Funtime Freddy, Minireena, Adventure Spring Bonnie, Springtrap, and Adventure Springtrap.
The date is supposedly 10/7/16, but it may release in late September. More likely to be released just before Halloween. DON'T GET TOO EXCITED, THIS IS SPECULATION, NOT OFFICIAL.
