Neville

Neville, the Bookish Father is the first Portrait Ghost that Luigi encounters in Luigi's Mansion. He is tall, lean, with orange hair and an orange moustache and dons a purple robe.

Neville is found in the Study on the second floor's west wing of the Mansion, the husband of Lydia and the father of Chauncey, Henry and Orville. Luigi found Neville reading on a rocking chair, previously warned by Professor E. Gadd that Portrait Ghosts were harder to catch. Soon books began to fly out of the shelves towards Luigi, damaging him five HP if they hit, and would disappear if sucked by his trusty vacuum. After the books launched, Neville would yawn, making him vulnerable, then, once some weak pulls came through, Luigi captured the portait ghost, earning the key to the Master Bedroom.
