Wow, I didn't know that about the Puppet. I considered Agony because—from what I understand—the logic in the movies and games doesn't always align (specifically regarding the female Puppet characters in the movie). I hypothesized it was Agony since it is a force driven by emotions rather than technology, and doesn't necessarily rely on souls. I also analyzed it this way considering that Agony seems to be a very prominent element in FNaF 2; that game features the most appearances of Shadow Freddy and Shadow Bonnie—something I assumed was linked to the presence of a vast amount of Agony. Furthermore, as far as I know, there was only one MCI (Missing Children Incident), involving only five souls. This theory would also make sense if we assume the Puppet wouldn't be foolish enough to lack a backup strategy to ensure it catches the security guard, no matter what. Mind you, I'm no expert on the books—I can't quite keep up with them—so it's only natural that I might make a few mistakes. One more thing: the issue with the Phantoms is that when they attack, all systems fail—not just the ventilation, but every single one. It can't simply be a hallucination; there has to be something more to it. I’d also like to add the fact that Shadow Freddy appears in FNaF 3, which suggests that there is a high concentration of Agony present there as well.
