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 acronym "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.
