The victory jingle comes from The Battle Cats, PONOS's long-running mobile tower-defense game built around armies of odd, cartoon cats battling across stages. Players hear it each time they clear a stage, so it became closely tied to progress, rewards and unlocking new units. As gameplay clips, speedruns and funny cat-team videos spread on YouTube and TikTok, the short tune travelled beyond the game itself. Creators now reuse it as a quick audio shorthand for success, because even viewers who have never played recognise its cheerful, triumphant tone.
