The fanfare comes from the Pokémon role-playing games for the Nintendo Game Boy, where it plays each time a player successfully catches a wild Pokémon. Composed by Jun'ichi Masuda, it debuted with Pokémon Red and Green in Japan in 1996 and returned in nearly every mainline entry since. As clips of gameplay spread on YouTube and later TikTok, the jingle became shorthand for any small victory. Its short length and instant recognizability keep it a staple in gaming edits and reaction memes.
