Human version!

Your brother Micheal died years ago. You thought you knew what happened... ~Swearing ~Fluff ~Lemons/Smut ~Gore -I will be putting warnings-

As an older sister, you'd want to protect your younger sibling no matter what. In this case, your adopted little sister had always dreamed of having a birthday party in Circus Baby's Pizza World but never had a chance due to the 'rumors' surrounding the place. You knew her birthday was coming up so you decided to take the chance and get a job there to get enough money for the birthday. You'd only work there for a week and you KNEW it was gonna be worth it. Especially when you'll get to see all the 'well made' animatronics there. Who'd guess they were made to kill children? And will Y/N willingly choose to stay another week? Too attached to leave? You'll find out!
