Toad, Toadette, and Gender

[Sengir]

And no, she doesn't just have a "gendered appearance", she has a gender identity within the context of the game. Characters, in dialogue, refer to her as female. She does not correct them, and instead chooses to wear that gender.

see this is the "grasping for straws" i mentioned
the producer (he's the guy making the game) for captain toad (that's the game) said that toadette has a "gendered appearance" but no sex
we dont have the original japanese, but you could check what word he used for "sex" (since sex and gender can be seen as synonymous to translators)
