The sound comes from Dubidubidu, a Spanish-language children's song by Chilean singer Christell, whose bright chorus was rediscovered years later on TikTok. There it was paired with clips of a cat dancing and spinning, and the chipi chipi chapa chapa hook became shorthand for cute, chaotic energy. The format spread through pet videos, fan edits and reaction clips, and creators still use it because the melody is instantly recognisable, easy to lip-sync and perfectly timed for short, looping videos.
