You know what makes me really sad? Her friend probably thought that Poppy locked him in the room so that she would get ‘adopted’ instead of him, instead of sacrificing herself.
@Srinija Nandi No, she saw that they were turning the adopted kids into toys and that the scientists were going to do one last experiment, it was between her and the other kid so she sacrificed herself to save him.
Is that animation actually canon to poppy playtime because I kinda hope it is, kinda shows that poppy isn't all bad, she sacrificed her life to save her friend
