The game takes place after the second ONAF game. The Beaver awakes from inside of the toilet as a zombie/mummy and wants to take revenge on his past friends. After Flumpty kidnaps another person for his hide n' seek game The Beaver kills him and his other friends turning them into phantoms. After killing them, The Beaver goes after the person to kill him/her too.
Basically the same as FNAF 3 but with Flumpty characters and the fact you only have one night. At first only The Beaver goes after you, but phantoms of the other characters will appear as the night goes on.

Are secret things in the game. You can play different minigames by clicking in some drawings or objects in the office or in the camera feeds. In every minigame you play as a different character, their goal is to run away from The Beaver, but they will always get killed in the end.
