I'd imagine its gotten be tough sitting there all day in the shadows of a closed curtain stage. Think it would just drive you insane when the night comes around to just run around. yes I'm talking about Foxy XD It drives him crazy and maybe just getting the guard can redeem himself to the crew to join them someday. And not left out.
whats above is just to classified the difference. Originally I just call Bonnie in general BonBon as a pet nickname for him cause it sounds cute. Personality wise Bonnie being tsundere like and Bonbon sorta yandere like if involved with a characterxOC story.
