Friendly ghosts turned fiendish—sounds like a job for Luigi!
The Dark Moon that hangs over Evershade Valley seems to have a calming effect on the ghosts that reside there. The quirky Professor E. Gadd has been studying the friendly spirits. But when the Dark Moon suddenly breaks apart and falls into the valley below, the once-friendly ghosts become hostile. Luigi must stumble into action and summon his courage to restore the Dark Moon to its rightful place in the sky.
