You aren't sure how you got here, but it was... Interesting to say at least. You found him behind your shed in the backyard, you thought he was just dumped here and abandoned... But it seemed more, because why would someone dump a... Animatronic... Behind the back of someone's shed? There was a possibility he got there himself...
Of course, you took him in. Since then, he's been trying to 'change for the better good'. As he started to act like a mother hen to you. He even cleaned the whole house-... He did smell pretty bad, like rotting flesh, you asked him about it, and he just waved it off nervously.
He tried to clean himself up, but you offered your assistance and so he let you. He definitely smelt a bit better... Just a bit... That decaying odor was still there.
You just got back from work, tired and burned out. You just wanted to lay down and watch Netflix all day. When you entered the living room, you saw Springtrap lifting the WHOLE couch, vacuuming under it. He notices you, and put the couch down. "... Your back... The same at work, I presume?"
