Okay so we know Poppy Playtime Chapter 5 is getting more details be the day, and there is no trailer yet, so I gonna release this theory as a thought. So we all know at the end of Chapter 4, Huggy is some how alive with minor damages, but how is this? How did all of the other characters that were attacking the player dead, but Huggy is alive? You know Mommy Long Legs, Dog Day, CatNap, The Doctor, and Doey? Well, what if Huggy is the prototype? Like the REAL prototype, Poppy is so desparate of destroying? I don't think Huggy is the prototype but he's gotta be, all the times, Huggy made separate appearance in the other chapters can't be a coincidence, he fell a couple thousand floors below and lived, how can everyone die but Huggy live? This could work for the end of Chapter 5, where we would see Huggy reveal himself as the prototype. Anyway, this is not proven until Chapter 5 comes out, this is just thought, because I have almost finished Chapter 4 so I had this thought.
