The Game Boy Horror SP is an item invented by Professor E. Gadd that appears as an equippable item in Mario & Luigi: Superstar Saga. This item can only be obtained by creating a different blend of espresso at Starbeans Café for the seventh and final time. The Game Boy Horror SP is the successor of the Game Boy Horror from Luigi's Mansion.
The Gameboy Horror SP resembles a real life Game Boy Advance SP .
With the Gameboy Horror SP, there is a chance that enemies (not bosses) will drop rare items at the end of battles. This is helpful when trying to get a good item along the quest.
