Princess Peach has been Mario's central princess since Super Mario Bros. in 1985, and her voiced giggles became familiar as the series moved into full voice acting with games like Super Mario 64 in 1996. Short laugh clips of the character spread through gaming forums, YouTube edits and soundboards in the 2000s and 2010s, often paired with screenshots of Peach smiling or teasing Mario. The giggle remains popular because it is instantly recognisable, family friendly and flexible enough for reactions, memes and lighthearted gaming content.
