Class 1-A gets teleported into Fnaf, the pizzeria: Freddy Fazbear's Pizza. You were the soul that possessed the Mangle animatronic. Which you were murdered by William Afton (Dave Miller). It was a brutal murder as well, and currently you were out the Mangles body, when 1-A was teleported.

They saw the Show Stage which had Toy Chica, Toy Bonnie, and Toy Freddy. While the mangles room was in another room in a cove set up stage. With just the Mangle using it. The backroom having the withered animatronics: Withered Foxy, Withered Freddy, Withered Chica, Withered Bonnie. And the Prize room having the Puppet.
