In the Night Garden is a British children's television series created by Andrew Davenport and first broadcast by the BBC in 2007. The Ninky Nonk is the train that carries Igglepiggle, Upsy Daisy and the other characters around the garden, stopping with a distinctive toot. Clips from the show later circulated as memes among viewers who grew up with it, much like Noot Noot moments from Pingu, and this panicked warning became a standalone reaction sound detached from its gentle original episode context.
