Louie is a recurring character in Nintendo's Pikmin series of real-time strategy games, first appearing as Olimar's co-worker in Pikmin 2 in 2004. Instead of spoken dialogue, the series gives its tiny explorers short bursts of playful alien gibberish, and Louie's chirpy vocal tics have become fan favourites. Short clips of his voice circulate on soundboards and meme pages, where creators reach for them as quick reaction sounds. The series' gentle tone and Louie's hapless personality keep the clip in rotation years after the original games.
