What are the spawning conditions for the nude/shadow versions? (Aside from nude Night 4 Fexa and Fredina.)
I've encountered nude Bonnie at the entrance after the power outage and have seen a shadowy Chica wandering the halls.
I think Shadow Bonfies show up when your sanity is low. Haven't played a whole lot yet, but the two times I've seen it happen, my Sanity happened to be low.
