Poppy Playtime Chapter 4 picks up where the last chapter left off, after showing another VHS ad for one of Playtime Co.'s toys from when the company still operated. This time, Doey takes the spotlight in both the ad and the concerning home video clips that follow it. Taking place in a prison this time around, where Playtime Co. is no longer hiding the sinister experiments they conduct behind the guise of innovation and making children happy, how does Chapter 4 live up to expectations?
