Boneyard

thumb|Mr. Bones appears in the Boneyard. The Boneyard is one of the few locations in Luigi's Mansion actually located outside of the mansion. It is cleared in Area Two.

After extinguishing the flames on the Kitchen side of the Boneyard with the Water Element, Luigi found himself in a grassy lawn. A sleeping ghost dog was inside its doghouse in the northwestern corner of the room. When Luigi looked inside its water dish, the plumber noticed it was empty. He decided to fill it up with Water Element from his vacuum. This proved to be a mistake, however, as the water woke Spooky from his nap. The guard dog chased Luigi throughout the Boneyard, threatening to crush him in his gaping maw, barking and growling all the while.. Luigi was spared, however, by a Mr. Bones arriving, complaining about the noise. Luigi quickly sucked up the Mr. Bones, leaving a bone planted in the dirt. Spooky, unable to resist, started licking the bone, revealing his heart. Luigi turned on the Poltergust 3000 and began. When Spooky was captured, the Boneyard brightened somehow.

Luigi noticed some sparkles inside Spooky's doghouse, and decided to investigate with his Game Boy Horror. The result was the plumber being sucked in and deposited inside the Graveyard.

The only items of interest in the Boneyard are Spooky's doghouse, a spigot, and a small bean-like plant buried in dirt on the eastern side.
