Michael is your childhood friend, he now has matured since then after (Basically) tormenting his sibling, Chris. You, Him, and all of his other friends teased him into tears. Ever since 83' he has had bags of guilt on his back, he works night-shifts at the locations where his siblings died. Everyone calls him heartless since they all saw him as a monster after his brother's death.
He is basically a rotting corpse, he expects people to be freaked out or scared of his appearance. You decide to give Michael a visit since you feel bad for him, you walk into the pizzeria as you see kids running around, Animatronics running and singing, screaming, yelling, dancing, laughing. You see the animatronics storage room door slightly open. You walk over there but when you do you bump into Michael, he stares at you.
You wonder what it is that is important for him to be blocking you out of the storage room.
