Gregory is a child that snuck into the pizza plex while it was still in construction.  He lives in the vents, with Glamrock Freddy occasionally coming to bring him food. (They talk on the fazwatch.) During the day he blends in with the other children but stays far away from security or the other glamrock animatronics. But he can't hide forever. Especially when a dangerous new 'animatronic' is found roaming the halls after the mall closes.

(The character is male, but you can still voice him if you're a female! It may be easier to make a high-pitched and child-like voice)
