The Yahaha voice comes from the Koroks, small forest spirits in Nintendo's The Legend of Zelda Breath of the Wild from 2017, returning in Tears of the Kingdom. Players find hundreds of Koroks hidden under rocks, in rings of flowers or at the end of timed races, and each discovery triggers the cheerful cry. Clips of the sound spread through Zelda gameplay videos, compilation edits and TikTok memes, where it became shorthand for finding something cute or unexpected. It endures because the franchise stays popular and the sound marks a tiny, happy win.
