The Game Boy Horror is a machine designed by Professor E. Gadd in Luigi's Mansion. It allows him to communicate with Luigi. It also has a map, Luigi's stats, the portrait ghost's descriptions, and a radar for Boos. The map and inventory are accessed by pressing Y Button and Z Button, respectively. Luigi can look in the Game Boy Horror's camera screen when the player presses X Button so they can see the mansion in the first-person perspective. The player can also select certain objects and have Luigi say something about it, much like the Tattle ability in the Paper Mario series. Additionally, if Luigi scans an object that sets off the Boo Radar, a square with a question mark and the text "What's This?" appears onscreen, even if the room is still dark. If Luigi checks a mirror with the Game Boy Horror, he is warped back to the Foyer automatically; however, this does not work with the mirror in the Mirror Room. In the Nintendo 3DS remake, the Game Boy Horror's search function is used by pressing Y Button, while the map and inventory are shown on the Touch Screen.

The Game Boy Horror was designed after the Game Boy Color, specifically the Japan-exclusive clear color variant, with the "HORROR" on it even resembling the Game Boy Color's "COLOR," even though the Game Boy Advance was already released. This was because throughout the early conceptual development of Luigi's Mansion, the then-unreleased Game Boy Advance's design was wavering throughout.[1][dead link] In Luigi's Mansion: Dark Moon, it was succeeded by the Dual Scream.

The Game Boy Horror was going to be an item in Mario & Luigi: Superstar Saga,[2] but it was replaced with the updated Game Boy Horror SP, modeled after the Game Boy Advance SP, which can be used to get rare items in every battle and is earned after the player mixes every Bean Juice blend in Starbeans Cafe. Also, E. Gadd twice contacts the cafe by using a giant two-way Game Boy Horror that is capable of warping items between the two locations, demonstrating this ability during the second time. A side effect of the Game Boy Horror's arrival is that it causes a blackout in the vicinity.
