Luigi’s Mansion: Dark Moon, also known as Luigi’s Mansion 2 in some regions, was released for Nintendo 3DS in 2013. During the game, inventor Professor E. Gadd contacts Luigi remotely to provide guidance and advance the mission. The incoming-call ringtone became familiar to players through these recurring interruptions. It remains useful online because it functions both as a recognizable piece of game audio and as a practical notification sound for edits, messages, and custom phone alerts.
