The Dual Scream (which, at first, E. Gadd called it the Nintendo DS) is an item that is seen in Luigi's Mansion: Dark Moon. It is invented by Professor E. Gadd and used by Luigi for the rest of the game. It replaces the Game Boy Horror from the first game. Luigi gets it before E. Gadd sends him to the first mansion: Gloomy Manor. The Dual Scream is always activated and the player can use the Touch Screen to check on certain areas. Its ringtone is also a speed-up, remixed version of the original Luigi's Mansion theme.
