Luigi's Mansion launched for the Nintendo GameCube in 2001, with Luigi exploring a haunted mansion to rescue Mario and collecting keys to open new areas as he cleared each section. The key jingle became familiar to players who spent hours backtracking through its rooms, and later clips of it circulated in gameplay videos, streams and edits as shorthand for progress. It endures because the short melody is instantly recognisable to Nintendo fans and neatly marks a moment of achievement without needing any explanation.
