Well, I believe what Prima said mainly because Nintendo has never said ANYTHING about Toadette's character other than the fact that she's Toad's partner for the game. If they had, I'd have accepted it rather than what Prima said. Besides, if I wanted Toad to have a love interest, I'd prefer for her to have a more imaginative name than simply his own name with a feminine suffix. That's why, in my fanfics, Toadette is Toad's sister.
