The Graveyard is located north of the Boneyard; it is an enclosed rectangular area with eight tombstones that occupy most of the room. At the top-center of the location is a small slope with a few steps leading to the main headstone, which Bogmire rests under. Two torches appear on each side of the tombstone, and a Fire Elemental Ghost can spawn from either one.
A single Red Jewel is the only treasure in the Graveyard. Luigi can obtain it from the downspout at the bottom-right corner. Some tombstones may release a Heart if Luigi taps them, but the top-left one always releases a large Heart that restores up to 50HP.
After Luigi vacuums up Spooky in the Boneyard, he must scan Spooky's kennel for it to make a small gust of wind dragging him into the Graveyard (similar to entering the Hidden Room from a mouse hole in the Butler's Room).
After entering the Graveyard, Luigi must tap a gravestone directly below the main one to summon three Mr. Bones (or five in the PAL Hidden Mansion). After capturing each of them, a blue aura glows around the main headstone. Luigi must walk to it, causing lightning to strike on the tombstone, making Bogmire rise from it. Luigi then screams in terror and is transported into an arena to battle Bogmire.
