Bowser Jr, the son of Bowser and a recurring character in Nintendo's Mario series, first appeared in Super Mario Sunshine in 2002 and has since shown up across platformers, kart racers and party games. Short voice clips of the character, including his panicky scream, became easy to reuse once soundboards and short-form video editing took off, because the sound is instantly recognisable to Mario fans even without any visuals. Creators keep using it as a quick shorthand for cartoon panic, especially in gaming fails and reaction videos where a longer sound would break the timing.
