FNaF 2 is filled with subtle Easter eggs and rare occurrences that add to its mystique:
- Shadow Freddy: A rare chance for a dark, shadowy Freddy to appear in the Parts/Service room (CAM 08). He is harmless but a creepy sight.
- Shadow Bonnie (RWQFSFASXC): Can rarely appear in your office. He is also harmless and will disappear if you put on the mask or raise the monitor.
- JJ (Balloon Girl): A rare variant of Balloon Boy that can appear under your desk. She is harmless and will disappear if you raise the monitor.
- Paperpals: The paper cutouts of Freddy, Bonnie, and Chica on the wall can sometimes move or disappear.
- The 'It's Me' Message: This iconic phrase can randomly flash on screen or appear on posters, hinting at the presence of a vengeful spirit.
- Endoskeleton: A bare endoskeleton can rarely be seen in the Prize Corner (CAM 11) or the Left Air Vent (CAM 05). It is harmless.
- Mangle's Radio Static: The Mangle's static can sometimes be deciphered to reveal cryptic messages or even morse code.
