tbh if they all say wowie zowie when they become elephants then i'm glad wario isn't in the game, or would he be another character for filthy casuals and basically be perma-elephant (except for wonder flower effects obviously)
i should reiterate on my last post, he'd have the elephant moves, but in his own style (trunk attacks=wario attacks, water=drinking it and spitting it out, breaking blocks=shoulder bash), and no damage
