Narwhals began as a short animated song by Weebl, released online in 2009 and built around a simple repeated chorus and a cartoon narwhal. It spread through early YouTube and animation sites as a shareable earworm, in the same era as other looping internet songs. Its appeal was the contrast between a real, little known Arctic animal and an overconfident, cheerful description of it. The clip is still reused because the tune is instantly recognisable, works without context, and signals lighthearted absurdity in just a few seconds.
