Dual Scream

The Dual Scream is a machine designed by Professor Elvin Gadd in Luigi's Mansion: Dark Moon. Dual Scream is a pun on "dual screen" - the abbreviation "DS" in Nintendo DS, which is what the Dual Scream is modeled after. It functions like the Game Boy Horror and displays a map of the mansion and the pause menu on the 3DS's bottom screen. Its ringtone is a remix of the original game's theme.

Trivia

 * The speakers of the Dual Scream are now shaped like E. Gadd's head instead of their usual rectangular shape.
 * While the Game Boy Horror had its full name from the start of Luigi's Mansion, the Dual Scream got its name midway through Luigi's trek through Gloomy Manor, when E. Gadd thinks up the idea after noticing Luigi scream so much.
