Well someone was bound to post it!
I just read the biological taxonomy discussion in the "Women of the Mushroom Kingdom" post and it got me thinking... What do you guys think Toad is? Male? Female? Hermaphrodite? Genderless freak of nature? And I am not talking about all the shrooms and Retainers walking around the Mushroom Kingdom. I am talking about Kinopio/Toad, the guy who was playable in SMB2, races in the Mario Kart games, etc. So?
(After we clear this matter up, we can get started on exactly what Birdo is.)
