  6. My favorite animatronic is the puppet personally. Though why wasn't she an option????

  7. Imagine if we just picked Slender 😰

  8. But the pigtail girl is not c.b not Even Afton's child I think it is Elizabeth afton you can see from one of the mini games sry if I was sooooooooo late to post, this have a good day😁.

  9. ah yes, every time I watch one of his videos, I get a “rocket” ad with him in it

  10. my favorite is springtrap i kinda like blood


  12. Rewatching these videos is funny because you know he’s not aware of the amount of sanity he’ll lose in the future.

  13. The people that voted for the slenderman theory are probably glad they lost

  14. My theory is that we are not playing by henry and not William Afton but i am not saying it’s the good theory and my favorite animatronic is spring trap

  15. Who else thinks that Matt’s FNaF series is amazing and you watch it all the time and understand the lore even though your only 11 🤣 🤪

  16. My favorite animatronic is Lolbit

  17. I think Charlie is in the box, since in "The Fourth Closet" Aunt Jen hid a Charlie in there (There are like 4 Charlie's, idk if it is the real one).

  18. I love these series, this fandom is amazing!

  19. William Aften is killing all the kids is not Henry he killed his self

  20. Plot twist:scot just frogoten the color so it tried a random yellow

  21. Jesus is coming back so you guys need to repent from your sins and please spread the gospel and please give your life to Jesus and Jesus is the way the truth the life God so loved the world he gave his only begotten son so whoever should believe in him will not perish but have everlasting life
