Noot Noot comes from Pingu, the Swiss stop-motion animated series about a young penguin and his family, first broadcast in 1986. Pingu rarely speaks in words, instead communicating through expressive honks and gestures, and his cheerful Noot Noot became his signature call. Clips of the penguin circulated online as short reaction and comedy edits, where the honk worked without needing any dialogue or context. Its simplicity, silliness and instantly recognisable sound have kept it popular in memes, remixes and short-form videos long after the original show ended.
