When the player first enters the minigame, they are greeted with a screen mimicking a computer desktop, with a background image of a tree and a single icon labelled "Foxy.EXE". The player must double-click on the icon, at which point the background will turn red with what is presumed blood for a moment before launching into the actual game.
The player controls Bonnie with WASD, namely A and D to move left and right respectively, while Withered Foxy's head scrolls through the background with various distortion effects. The player must dodge some simple obstacles to get through the game. If the player is hit by one of the obstacles, Withered Foxy's head will flash in the background, playing the jumpscare sound, signifying a hit. If the player is hit three times, Withered Foxy will say "All your base are belong to us," resulting in a game over.
The player progresses through three areas in the game. In the first area, the player only needs to walk right to the end. Part of the way through the first area, the image of Withered Foxy in the background will change so that he is looking at the player.
In the second area, the player must again walk right, but occasionally will be jumped by Withered Freddy. Once Withered Freddy appears, the player must immediately turn and walk the other direction until Withered Freddy fades away, at which point the player can proceed through the level. Alternatively, moving slowly will prevent Withered Freddy from appearing at all.
In the third and final area, as the player progresses through the level, a kitten will start moving toward them. The player must avoid the kitten by hiding behind dark building-like shapes, where the kitten will be unable to see the player. Usually the player will need to backtrack a bit to find one such hiding spot.
Finally, upon reaching the end of the third area, Withered Foxy's head will appear once again in the background, fading out to signify defeat. Upon beating the game, the player will unlock Nightmarionne.
As the player progresses through the game, Withered Foxy's voice will play in the background on loop, giving clues as to what should be done in each area.
