Hallucinations

Hallucinations are weird images that happen ingamee.

SatanBob
See article

SatanBob is like Golden Freddy in FNaF1, he stands there, makes a creepy face, and crashes your game. SatanBob is the same model as Normal Spongebob but retextured.

Again, the model of SatanBob is the same as Spongebob's (from Plankton's Robotic Revenge) but retextured.

Plankton

He won't kill you. He appears super-rarely. He sits on your desk, making no noise. He only dissapears when you use your Monitor.

The model is ripped from the PSP version of Yellow Avenger

If you play this audio clip found in the game files, then it revels a picture of a face from the old Klasky Csupo Robot Logo and a picture from the bootleg copy of a Spongebob Episode.

It was orignally a sound that would appear anytime at the Kitchen around 2 AM to 5 AM, but got cancelled

It now appears on the 5th night call, when your roomate dies on the Night 4 call.
