Luigi is the younger brother of Mario in Nintendo's Mario franchise, first appearing in the 1983 arcade game Mario Bros and becoming known for his green outfit and nervous, good natured personality. Telephone themed clips using familiar game characters spread widely as mobile ringtones and soundboard uploads during the smartphone era, where a recognisable voice or melody could turn a normal call alert into a joke. This longer Luigi version remains popular with gaming fans who want a nostalgic, light hearted alert rather than a standard phone ring.
