The Rush Threat
Foxy is the starter enemy that turns neglect into instant pressure. That makes him feel bigger than he is.
Foxy is the starter threat most likely to hijack a player's whole mental loop. He is dangerous, but the real mistake is letting Pirate's Cove become the entire night. Foxy is built to teach controlled attention: check him often enough to keep the rush in check, but not so often that the rest of the office disappears from your map.
Foxy is the starter enemy that turns neglect into instant pressure. That makes him feel bigger than he is.
His job is to force you to reserve part of your loop for Pirate's Cove without letting that reservation become panic.
Most Foxy deaths happen because the player reorganized the entire run around him and forgot the rest of the office.
Players often think Foxy killed them. In reality, Foxy usually got them killed by making them ignore something else first.
Foxy is the first strong lesson that information itself has a cost. You cannot look everywhere all the time just because one threat scares you.
He also teaches when it is correct to act before the attack has fully arrived, as long as the state reading is solid.
This is the most common mistake. Foxy becomes the whole run when he was supposed to be one slot inside the run.
The opposite mistake also kills people: assuming one check bought infinite safety.
When Foxy actually commits, hesitation is expensive. The door decision has to be fast and calm.
Foxy punishes players who use cameras reactively instead of rhythmically.
