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 at first, he is an ally of the babies at the end of Diaper Duty DS. However, in Yoshi's Story 3, Baby Waluigi becomes a Star Child when he completes his own minigame. When Waluigi was born his first word was "Bob-omb." Then he would say things like "Wario," "bad," "Mario," and "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. Whenever Baby Waluigi was in danger, Baby Wario would rescue him, and is protected by Baby Wario, though they have no family ties.
He is also a boss with his partner Baby Wario.
