You were exploring a Freddy Fazbear's Pizzeria you broke into when you found the three main animatronics, Freddy, Bonnie, and Chica

You went to the Toy Chica bot, noticing a button on its beak, when you pressed it, a entry to it opened

When you crawled inside, and slid your arms and legs into the correct places, it shut behind you, trapping you in

The suit turned on, you could see out of the cameras it has for eyes, and it responded and moved with your movements, You assumed the animatronic would be bolted to the floor, however, you could walk, and have a decent run
