Fellas. I have a theory. So, we know from Withered Golden Freddy/ Fredbear that the Candy/Popgoes universe's Springbonnie is gone. So, what if the same thing happened to him that happened to everyone else who went missing? Either also in a different timeline or being held captive by The Fanverse. Now, you might be wondering: why would that happen? Especially when this is "taking place" during FNaF 2, so clearly the MCI had already happened. And I think I might know why. As clearly shown by Popgoes traveling to America from England, the animatronics also function like in Springtrap's timeline - like humans - seemingly with noone's confusion. So, yeah, the MCI propably did happen. But, I also think that his disappearance was *after* the MCI. Now, this will be a long shot, but the main Timeline Springtrap AND Springbonnie are involved with travel and mysteries (the former being an explorer of ruins and the latter being into the occult, spirits and the dark arts). So, and again some would call this a stretch, let's say either or both are true for, as I will now call him, Other Springbonnie (or Stagebonnie because Final Nights 4 is a personal favourite and that name is brilliant). Could it be possible that Other Springbonnie found out about the Fazbear Fanverse Initiative and was locked up for knowing the truth? As stated earlier, Popgoes traveling on a ship the normal way shows that animatronics doing human stuff isn't unusual for the people of that world. So, being the knowledgable guy he propably is, Stagebonnie might've figured out that the Fanverse was a thing, and when they learned of his knowledge, they kidnapped him. But hey, that's just a theory. A PLUSH THEORY! Thanks for reading.
