    Petscop is the biggest mystery in gaming that you can't play. We've talked a lot about this non-game. Throughout our other theories we've uncovered who our cast of characters are, what this game actually is, and more. Yet there are still so many unanswered questions. Today, Theorists, we are going to tackle not one but TWO of these mysteries. Hold on to your screens, this is going to get DARK!

    I think I figured out the door riddle,
    When a door is open and you look at from behind, it looks closed but when you go to the other side of the door it looks open, the door was never closed at all

    The wind opened the door because if you look at it, it looks like the door is shown through a window that has no glass. But hey that`s just a theory, a RIDDLE theory.

    I have a theory! What if Paul, if that’s his real name is like daisy brown yea her that girl with the weird alien thing. Paul made this entire thing up and none of these people are real. Paul made petscop and is acting and replaying the game he made. Also, like Daisy Brown he posts on TVclip videos and everything is messed up. BUT THATS JUST A THEROY A GA- Oh wait... THATS JUST A THEROY AN AVA THEROY!

  • Gacha Koi
    Gacha Koi 8 days ago

    My answer is a bit long...

    So if NO ONE opened the door, that means NO PERSON opened the door.
    And, he did say the answer is what it’s all about, think of the title. “The Music and the Madman.” The madman is a man, so he nor anyone else could open it. But music. The music can send a musical tune that
    Triggered the door to open. If not, NO ONE is a person. Petscop already has a eerie backstory, and if you think bat to Petscop, the theory video, then you know this is probably a reference, actually, a game about a child’s death, but a distressed child, who, died. Now it’s really “Products” of distressed children. The top is a cheery, (Yet still suspiciously eerie.) world, of a child! Now the bottom is a depressing view from Candances, 2nd, life. When Paul, (The discover of Petscop.) deposits her, (Candance.) that is her death. So, back to topic, Candance opened the door. She isn’t alive, therefore, you wouldn’t classify her as a ONE, because the ONE states, “of living matter; alive.” So you can’t call her much anything but, a ghoul.

    I find a lot of similarities between Marvin doing terrible, abusive crimes involving children, sometimes including murder, then getting trapped into something (Springbonnie/ Springtrap) as a consequence, and Purple Guy (William Afton I think) doing terrible and abusive crimes involving children, again, often being related with murder, then getting trapped into something (Petscop) as a consequence. Also, just think about something... Michael Hammod is Michael A, in a happy status. Unless... Michael A.... and.... Michael Afton! You thought you were done with FNAF, MatPat.... but, you have barely just scratched the surface.
    But hey, that’s a ~~theory~~ joke... an ~~GAME THEORY~~ UNFUNNY JOKE!

    So care isn’t dead, right? What if it was passed nit from, Rainer, Marvin, Paul, but, Rainer, Marvin, care, Paul. Paul said his mom had it, what if his mom is care, but that’s a nickname. And remember the cadence newmaker theory? I think it’s still connected, and that there are more connections to other major Child deaths. Just a thought, and I’m only like 8 minutes in so idk if you thought care could be Paul’s mom or not sooooo
