Baby Luigi first appeared as the baby rescued in Super Mario World 2: Yoshi's Island in 1995 and later became a playable lightweight racer in Mario Kart games including Double Dash and Mario Kart Wii. As Mario clips spread on soundboards and short video platforms, his high pitched cries and giggles were cut into standalone reaction sounds. Fans use them to reference Nintendo nostalgia without needing gameplay footage, which is why the clip still circulates among gaming editors and meme creators.
