Henry and Orville

Henry and Orville, the Twin Brothers are two ghosts from Luigi's Mansion.

Henry and Orville are the sons of Lydia and Neville, they are also the brothers of Chauncey. Henry and Orville's favorite game to play is hide and seek and since they both like to hide the game usually lasts a long time.

When Luigi first entered the Twin's Room room, he found it empty. To lure the twins out of hiding, he used his trusty vacuum to spin an airplane mobile hanging from the ceiling. The twins decided to play hide and seek with Luigi. They told him to wait outside until they were ready. When Luigi re-entered, both were hiding in one of five boxes. Using his Poltergust, Luigi realized that a brother would shiver when his box was vacuumed or when an element was blown out. This helped Luigi easily win the game.

Unfortunately, the twins accused Luigi of cheating and sealed the door, then Henry got on a car and Orville got on an airplane and started attacking him. To make them vulnerable, Luigi sucked the car and the airplane, capturing each twin one by one. The easiest way was to first suck up the car and Henry while avoiding Orville as his plane dropped small bombs. Upon lighting the room, he retrieved Mario's Shoe.

Trivia

 * Neville writes in his diary in the Study that the twins are more afraid of the elements (fire, water, ice and wind) than the baby (Chauncey). Luigi can use this as a clue to find the brothers.
 * Only Orville gives up the pearls, so get him second.
 * Henry and Orville are named after Henry Ford and Orville Wright: Henry drives the toy car and Orville flies an airplane, which are vehicles the named-after's created.
