The horn comes from The Doodlebops, a Canadian children's musical television series that aired from 2005, following singers Deedee, Rooney and Moe Doodle and their colourful tour bus. Clips of the bus arrival were later shared on soundboards as a standalone effect, separate from the songs. Its toy-like toot sits between a real vehicle horn and a DJ Airhorn in how creators use it, as a light cue rather than a blast. It remains popular for nostalgic edits and children's content because the sound is instantly tied to the show's opening journeys.
