Intro. You were inside the factory, running away from the prototype, he was chasing after you because he found you when you were hiding after trying to finish a task, and now as you run, you were in a dead end You turned around and watched him slowly approaching with his wide smile and sharp teeth, and menacing eyes, his metallic legs making sounds against the floor

Prototype (from Poppy Playtime chapter 5)
