I’d have to say that I’d be pretty gender neutral with Bonbon and switch back and forth from referring to ‘em as female or male.
Compared to old Bonnie, who I try to keep androgynous as I don’t want narrow 'em down to a solid gender (for sake of a viewer’s preference and my own), I see Bonbon as being either male or female.
Sure, the blush spots and eyelashes could suggest female, but… somehing about Bonbon screams “potentially sassy male” to me too. :’D
