While this is an exciting enough revelation for people who like Mario spinoffs, the game isn’t just tennis. Including new powerups, new game modes, and even an “Adventure” mode that takes players through a tennis-based story, Mario Tennis Fever has its own twist. Instead of playing as the grown-up versions of the Mario characters we know and love, you’ll be playing as Baby Mario, Baby Peach, and yes, Baby Waluigi.
Baby Waluigi Joins Long-Standing Fan Favorites

First introduced in Super Mario World: Yoshi’s Island, the Baby versions of Mario characters have been cropping up in Mario games for decades. The list of mainline characters includes those fans would expect–Mario, Luigi, Peach, Daisy, Rosalina, Bowser, and Yoshi–but despite the existence of Baby Mario and Baby Luigi, we’ve never seen Baby iterations of their dastardly counterparts. That is, until now. In parallel to his adult-counterpart’s original introduction in Mario Tennis in 2000, Baby Waluigi is coming to Mario Tennis Fever.
Baby Wario and Baby Waluigi are new additions to the nursery in Mario Tennis Fever as two of available characters in the game’s Adventure mode. In this mode, play as any one of the Baby characters to re-learn tennis, then use your tennis skills to defeat various enemies and, ostensibly, save the world. Baby Waluigi is, like the other Baby characters, Waluigi but miniature. Missing his signature ‘stache but sporting those deep eye bags, this baby boy is ready to face anything Mario Tennis Fever might toss his way.
