So I feel like all the animatronics would have a nickname for Gregory, like how Freddy calls him superstar, therefore I have picked my favorites;
Roxy would be hotshot, I was thinking maybe punk but hotshot feels so much better than punk.
Monty would be little man, although not little dude. I feel like Monty would call himself a big man because he's shown to be the strongest of the animatronics (or at least the most willing to use his strength) so I feel like big man/little man would be perfect.
Sundrop is dewdrop and Moondrop is starbright, no context needed, its just fuckin cute.
Chica gave me the hardest time but definitely something like sweetpeach or sugarplum. She gives me fruit related nickname vibes, like Apple blossom or something.
Vanessa is included solely because I believe she'd call gregory lil shit or leash kid and want to share that
