Withered foxy is immune to the Freddy mask because his sensors are broken and he can see right through the mask to attack you

It’s very hard when you first play it because of Withered Foxy and the dang music box winding plus that little butthead balloon boy who steals your flashlight batteries from you to defend the toy and withered animatronics. By like night 4 and 5 you get used to it. But 20/20/20/20/20/20/20/20/20/20/20 is way worse with toy Bonnie and Balloon boy plus withered golden Freddy.
