Perfect gender = I like them having their confirmed genders as they are. Should have had the opposite gender = I don't like them as their confirmed genders; I don't really see them that way. Neutral on their gender = I don't mind them having their confirmed gender, even though I think they should have had the opposite gender.
All beans except Numskull and Calamity are female. Even if Ninny was female in the Valentines' Day video, as well as having a female-sounding voice in the song, Metro confirmed Ninny to be male.
