FNaF 2 Hardcore Mod

This would be a mod that makes FNaF 2 harder and the enemies more dangerous. This mod does not add any custom content or OCs, it makes use of existing characters and mechanics within the canon.

JJ
Balloon Girl AKA JJ is an animatronic with alarming similarities to Golden Freddy, she can shapeshift and cause hallucinations. On nights 1-3, JJ is not a threat if she appears under your desk, just a hallucination. The paper plate doll associated with her won't move either. But on nights 4-5, JJ can attack.

Movement
JJ appears as the paper plate doll in Party Room 4, and acts a lot like balloon boy: She laughs or says "Hi" or "Hello" when she moves, and she even evades the flashlight when she is in the central hall. Her movement pattern is as follows:

Party Room 4 -> Central Hall

Then, she appears in the office when you put the monitor down as a paper plate in the usual location. If you fail to put the mask on, she appears as JJ under the desk, causing power to contantly drain (explained later). She will not leave once under the desk.

Endoskeleton
This strange endoskeleton seems to have moved before midnight, or someone moves him. On Night 3, that bare endoskeleton becomes active. He acts similar to Freddy from FNaF 1, in that he starts moving on Night 3, but is not likely to attack until Night 4.

Movement
He acts kind of like Bonnie from FNaF 1, as they share the ability to skip rooms in a teleportation-like manner, and they move away from key locations as often as they progress to them. He also acts like Mangle, because he's always on the ceiling or wall. The endoskeleton starts in Prize Corner, for unknown reasons. His starting position is off camera. He then stands up, and then onto the wall. After that, his movement pattern is:

Prize Corner -> Game Area -> Main Hall

After that, he has two attack methods. He sometimes goes to the Parts and Services room and puts a Foxy head on.
