Mario Kart DS Deluxe is a fan-made ROM hack built on Nintendo's Mario Kart DS, adding custom tracks beyond the original handheld game. Raccoon City is one of its custom course names, and short music clips from these fan tracks circulate on soundboards because they are instantly recognisable to Mario Kart players while still sounding fresh. Creators keep using this brief snippet as a compact identifier for the hack, for custom-track showcases and for edits that celebrate fan-made Mario Kart content rather than official courses.
