The original aliens debuted in Pixar's Toy Story in 1995 as the little green men inside the Pizza Planet claw machine, who treat the claw as a mystical leader choosing who will go to a better place. Their unified ooh became one of the film's most quoted sounds and returned across sequels, shorts, and merchandise. Online, fans began recording impressions of the chorus and using the clip as shorthand for group awe, which kept the joke alive in reaction videos and memes long after the first film.
