Just like the zodiac signs, each of the monsters in Poppy Playtime have unique personalities, behaviors, and motivations that set them apart – thus, it's possible for players to use their birth time and place to find out which of the iconic villains is most closely aligned with their own nature. It can be entertaining to theorize one's role in any fictional universe, but the question becomes especially relevant when referencing Playtime Co., wherein it's rumored (and quite probable) that each of the murderous toys actually contain a former human employee, who has been trapped inside due to a cruel corporate experiment.
