Okay but imagine the glamrock group practically adopting Gregory into their little family.
They take care of him, feed him of course, and since they can't leave the place, they have whatever nightguards they have at the time take Gregory to get clothes.
But sometimes, Greg does have his down moments. Thinking about his parents and such (assuming he's orphaned and not just a runaway kid). It upsets him sometimes and he just isolates himself at times like that.
At this point, each animatronic knows what's happening. It isn't the first time, he's explained it before. And they decide to give him some time alone, and once they're sure he'd be okay enough for them to be near they go and search for him.
His hiding spot always changes. It'll go from one of those strollers, to behind the arcade games, to the slides of the daycare (even Sun and Moon know when somethings off with him, they can sense it.)
But once they find him, they sit next to him and offer hugs. Reassure him that everything's okay, and that even if it isn't the same, they love him as much as he could ever imagine.
They sit in silence for a bit, til Freddy comes up with a dumb little dad joke that makes them crack up in the moment, Monty groaning and teasing how dumb Freddy's jokes are, to which Fredboy responds to by dramatically clutching his chest.
It's enough to get Gregory to chuckle and that's all they really care about. Chica comments on how she could've sworn she heard something aside from Freddy's bad joke and everyone agrees, meanwhile Gregory knows what's coming, so he wastes no time in running.
They have a little run-around game, sort of like hide and seek. But once one of them has got him, they take turns giving him tummy scratches and raspberries. Soon enough he's tired out enough to fall asleep, and well , they form a cuddle-pile.
Of course, Sunnyboy joins in at some point too, he loves cuddles
