The sound comes from I Am a Gummy Bear, the English version of the dance song by the animated green bear character Gummibär. The character and song first went viral on YouTube in the late 2000s, with viewers sharing the bright cartoon video and its catchy chorus around the world. It later became a staple of meme edits, dance challenges and short-form video, where the short hook works on its own even for people who have never seen the full video. Its simple melody and instantly recognisable voice keep it popular with children and nostalgic adults alike.
