The cupboard is a small wooden space the player hides in during Night 3, it is a third room the player can hide in if they complete one of the achievements.

The mechanics of the cupboard can be devastating, if the player moves for a few seconds continously, they will cause a pot or a plate smash to the ground, but not breaking it. Due to it being a wooden space, it makes a lot of noise. This causes Mario's awareness to be higher depending on which room he is in. If he is at the kitchen, the player is killed immediately. The more away he is, the less the awareness will fill up. Mario goes to room to room and into the kitchen despite the player not being in the kitchen but the cupboard they are hiding in, is in the kitchen. Mario will keep going back and forth. Wario is a different matter. He knows exactly where the player is and if he fully enters the kitchen, he will kill you. The player must keep watching him on the cameras to slow him down but moving makes him stop moving. Yoshi is like mario but will only awaken if the player smash the plates/pots/idk first. He will then act like Mario. Finally, the player has a flashlight, they can use this flashlight to illuminate the darkness inside the cupboard. The flashlight doesn't have limited battery tho. Final thing is that if the player can cause the plates to shatter if they move too much (1/10 chance of happening)
