I never really had too much of a clear thought or backstory to this when I technically paired the two together in my little FNAF universe.

I believe it sort of just… happened. I vaguely recall me actually wanting to make a little series or pictures (of not a comic) at one point that portrayed a random story of how it came to be. And this actually fitted with the Freddy and Bonnie thing I mentioned I would’ve posted around Christmas, should all the stuff that went on with my FNAF work not have happened. And since I also feel I once publicly mentioned I’d tried to make this (which, I apologize, now won’t be the case), the general breakdown would’ve been:

Bonnie seen walking around the pizzeria (it’s after hours and the place is closed due to holidays). They appear to be looking in various rooms for something, before they come across Pirate’s Cove. Bonnie walks closer to the other side of the attraction and sees Chica and Foxy there, talking. Bonnie asks if they’ve seen Freddy, both shrug and say, ‘He’s probably somewhere around here.’ Bonnie slumps a bit and keeps looking.
Then it likely would’ve delve into Chica and Foxy talking again, this time how they knew where Freddy was, but wanted to give him space to think (which is where the Freddy and Bonnie thing would have taken off from), then more or less, it just clicks.

(Haha, sorry I went off on a tangent, I thought I’d at least reserve any past curiosities about where I planned to take that. Though, this more or less would’ve been to possibly satisfy curious folks/would have been fun!)

(And I really hope mobile Tumblr doesn’t make this a mere giant wall of text! If so, will fix in a little bit!)
