Game Reason (Reason Your For Mike)
Freddy Fazbears Pizzeria was once a popular restaurant for adults and children alike. However, due to a number of incidents - including the kidnapping and implied murder of  children by a worker wearing an empty animatronic suit, sanctions by the Health Department over the  reports of the mascots having a "rotting smell" ( mucus and blood around their eyes and mouths), and "The Bite of '87" (where a child was bitten in the head by an animatronic and loosing partial brain matter) - the pizzeria has fallen onto being shut down. Freddy Fazbear's Pizza is set to close by the end of the year, as potential buyers do not want to be associated with the restaurant's  reputation.  The four mascots - Freddy the Bear, Bonnie the Bunny, Chica the Duck, and Foxy the Pirate Fox - have a particularly foul stench and what appeared to be "blood and mucus" around their mouths, which concerned parents have interpreted as "reanimated carcasses". The Phone Guy remarks in the 1st Night phone message that the animatronics have not had a bath in their over 20 years of service. The stench could also be the missing children were stuffed into the animatronic suits after they were killed, and that the bodies are causeing the repulsive smell.

Due to the risk of their servos locking up from disuse, the animatronics have been left in a "free roaming mode" at night over the years. They used to be able to roam freely during the day as well but has been comprimised. It is now where you come in, you are to watch and make sure none of which happen again. At night during their "free raoming mode" you must protect the resturant and yourself. Once you have done so you will be paid, if you get through alive.
