Foxy

FNaF 1
Like the original game, Foxy hides in Pirate Cove throughout most of the game. The player has to constantly check on CAM 1C to see Foxy's current status. Foxy will often be seen peeking out his curtains as the shift goes on. The player also needs to balance the number of times they need to check on Foxy to prevent him from emerging. Failing to meet these requirements will result in Foxy moving out of Pirate Cove and running to the Office at full speed.

The player must quickly shut the left door to halt his attack. Despite this, Foxy will regardless drain the Office's power supply (depending on how the number of times he sprints). If the player doesn't stop Foxy in time, then the latter will proceed to jumpscare them and ending the night.

P.S. If you peak out of the office. Regardless of which night, he will sprint twards you even on night 1.
