Is moltenmcl Canon to your version or are they not in control here
First of all, I believe in MoltenMCI in the games but it also genuinely confuses me. Like, when the heck does William get the MCI remnants in the Funtime animatronics ? He kinda died right after dismantling them in the Fnaf 3 minigames, and plus the Funtime had already been around for some time, we know that because of Elizabeth's death.
Here, the Funtime animatronics have remnants but from the kids they have themselves killed. They aren’t linked to the MCI, and they aren’t controlled by any ghost or soul.
And aside from Circus Baby, none of the Funtimes are haunted either because there isn’t any actual ghost inside them.
