The revenge of purple guy

Prologue

It was 1987. My kid's birthday was today. Since I work at FredBear and friends, I get free parties. Usually an employee would only get half off, but I'm the guy who trains the new workers and also help out with the actors, I get it free. I'm always at work during the day so I get my oldest brother to watch him. My youngest son is superstitious about everything. He's scared of the animatronics, and that gives his brother a chance to scare him till he cries. He is also scared of his brother's friends. Says that they will lock him in his room or pick on him about his irrational fear of the animatronics. He had a stuffed FredBear, but he kept taking it everywhere so I gave it back to the pizzeria. A few days ago I saw him running from one of the employees in the FredBear suit, they can be in either suit mode or animatronic mode, who was only trying to give him back his stupid toy. I was in the back helping someone into a suit. He called to me for help but I was too busy. As I was looking for my son a young intern named of mine who always sounded laid back ran up to me eagerly. "Sir, sir. Your son, some kids, FredBear, blood everywhere." I ran to the stage to only see my oldest and him friends with masks of Freddy, Bonnie, Chica, and Foxy, the new animatronics before springtrap, panicking. I ask them what's going on and they point to the crowded stage. I move around the people only to see my youngest, on his birthday, almost dead without his frontal lobe. I burst in anger. "Who did this?! Who did this to my son?!" A concerned parent said, "Your oldest son and his friends". I looked at him in disbelief but his face said it all. "I have only one son!" I screamed as I left. The ambulance showed up and I waited to board it with my son. Later the doctor said that he would live but he would be in a coma for a long time. He said something else about nightmares but I didn't listen. I was too angry at those kids. I promised my son that I would avenge him if it's the last thing I do.
