I played through the game and got to where I met The Everyone as they are called. I noticed that the Candy's characters, Popgoes characters, the Jolly characters, and two others from fangames I don't think I've heard of were there. This is a lore question maybe so you have the right to not answer, but are Candy's, Popgoes, Jolly, and any other fangames connected to Mousy's?

If so, I think that is pretty cool and something you should keep in the lore, it's very rare for a Fnaf fangame to be connected to other fangames.
