This exists because yes.

I have a headcanon that Foxy managed to get out of the Pizzaplex before it opened and was never recovered, hence why the Glamrocks now have the hourly recharge (so they can't get far, unlike Foxy who was running on Duracell). Freddy got really close to Foxy before he bolted so he still misses him.
So yeah, Foxy dodged a bullet and disconnected himself from the network years before Glitchtrap tried getting control of it.

Glamrock Bonnie was most likely ripped apart by Monty, or the S.T.A.F.F team so Vanny could use the parts to make Burntrap stronger. If you see Burntrap's hands, you'll see claws, much like Monty's. If Bonnie was the bass player before Monty, they'd most likely have the same type of hand.
