Pikmin are the plant-creature helpers from Nintendo's Pikmin game series, which began on the GameCube in 2001, and their signature squeaks and sighs have become instantly recognizable to gamers. The relieved phew style sound spread as editors clipped these tiny vocalizations into reaction memes and short video edits, where a cartoonish sigh of relief works as a universal punchline. Its popularity endures because it is short, cute and emotionally readable at a glance, making it a staple of wholesome and funny compilation videos.
