Gruntilda is the main villain of Banjo-Kazooie, the 1998 platform game for Nintendo 64 developed by Rare, where she kidnaps Banjo's sister Tooty and challenges the heroes throughout her lair. Her cackling laugh became one of her most recognisable traits, heard whenever she taunts the player or celebrates a scheme. As clips from the game spread on soundboards, video edits and streaming communities, the laugh took on a second life outside the game itself. It remains popular because it instantly signals a scheming, cartoon villain without needing any dialogue or context.
