The phrase comes from Portuguese, where it translates as penguins do not eat dogs, and its appeal online comes from that simple, unexpected logic rather than from a known film, show or viral challenge. Portuguese voice clips like this often circulate as standalone soundboard sounds, shared between meme pages and chat groups where a random line becomes an inside joke. Without a story behind it, listeners focus on the delivery and the absurd statement, which keeps it flexible for different videos. Its staying power is in its brevity and strangeness, making it easy to reuse for a quick, deadpan interruption.
