Daisy was in... no, wait, Pauline was in Donkey Kong '94 and the original Donkey Kong. So is Pauline another Waluigi?
As for Waluigi making as much sense as the WarioWare characters... yeah, I agree, these guys came out of nowhere. But at least they have enjoyable interjections when you win/lose games. I'd go crazy from Waluigi sounds. And I like Dribble and Spitz. That reminds me, one YouTuber comment said that the Fudgehog noises in the Fudgehog romance dance for "Viva Pinata" sounded like Waluigi.
They really do. If I had to hear that in WarioWare... ugh.
And I second bullykoopa. When I saw that a decent portion of the cast for the new Mario Kart game (or baseball game or whatever it was) was just baby versions of characters, I threw my hands up in defeat. Toadette was pretty ridiculous, but Baby Daisy... there better be an upcoming Yoshi's Island game with all these babies just to give them a reason for existing.
