The hook comes from Dubidubidu, a 2003 children's song by Chilean singer Christell Rodriguez, built around nonsense syllables sung in Spanish. It faded for years before resurfacing on TikTok and YouTube in late 2023, when editors paired it with a bobbing cat and other pets moving in time. The contrast between the innocent melody and deadpan animals made it instantly shareable, spawning remixes and dance edits. It remains popular because the loop is short, recognisable in a second, and works without any context or dialogue.
