Crygor is amazing. It's sad that his grandaughter started getting more attention than he did. He's a far superior character. I blame the cute-ification of the series. Where cuteness started being more important than wierd and silly.
Even Kat and Anna had this wierd vibe about them. Remember the first WarioWare and how overly serious the their story and music was, then you're playing these super cutesy microgames? The juxtaposition of the super serious setting and the super cute microgames ended up hilarious and strange in all the ways WarioWare needs to be.
Even in Mega Party Games, they played this serious sounding music while sitting on top of a bunch of turtles. But after that, Kat and Anna were sadly played straight, and just... cute.
Don't get me wrong, I like cute. But in a Wario game the only way I want to see something cute is if there is a splash of strangeness to it.
