Pingu first appeared in the Swiss-British stop-motion series created by Otmar Gutmann, which began in 1990 and became known worldwide for its clay animation and invented Penguin language. Clips of Pingu reacting and laughing were later shared widely on YouTube and in meme edits. Like the baby laughing meme and the cat laugh meme, his giggle survived as a standalone reaction because it needs no context or translation. It remains popular for family friendly edits, nostalgic posts and short form videos built around innocent humour.
