Baby Waluigi is Waluigi as a baby. He has appeared as a minor character in a few games. He is very sneaky and plays tricks on Baby Wario and Baby Luigi. Though he is not a Star Child, he is an ally of the babies at the end of Diaper Duty DS (However, in Yoshi's Story 3, when Baby Waluigi completes his own minigame he becomes a Star Child). When Waluigi was born his first word was "Bob-omb." Then he would say things like "Wario" "bad" "Mario" "Luigi." His parents were so shocked, and wondered how a 1 day old baby could talk. Of all the babies, Waluigi could speak the clearest. Like Baby Luigi, Baby Waluigi is 3 years old. He is Baby Wario's younger twin brother. Whenever Baby Waluigi was in danger, Baby Wario would rescue him, and is protected by Baby Wario.
He is also a boss with his brother Baby Wario.
Baby Waluigi is a player on the Baby Brigade team on the multiplayer wii sports game Mario Rugby League. He is the fastest character on his team however he is the least skillfull and the weakest. His special skill is to unleash some vines for an extended tackle.
Baby waluigi is a main character and boss in Mario and Luigi: The Eight Orbs.
