The exact source of this clip is not widely documented, so it is best known simply by what listeners hear: a seal apparently saying egg. That ambiguity has helped it travel online, where short, easily reused sounds spread through edits, reaction videos and animal compilations rather than through a single show or film. People search for it by the phrase they think they heard, which keeps the wording consistent across uploads. Its appeal is low effort and high surprise: one animal sound, one familiar word, and a joke that needs no context to land.
