Uncle Grimmly

Uncle Grimmly, Hermit of the Darkness (or simply named Uncle Grimmly) (Japanese: ヤミノフ Yaminofu), is one of the Portrait Ghosts of Luigi's Mansion. He is only found during the blackout, in the Wardrobe Room.

Description
Uncle Grimmly has pale blue skin, just like most Portrait Ghosts, an oval-shaped head, small yellow eyes, and jowls. He has a brown coat with two opal buttons, a dark purple necktie and a boutonniere on the left side.

During the blackout in the Telephone Room, Professor E. Gadd calls Luigi on the furthermost rotatory phone, and he reveals more information about Uncle Grimmly: he only likes to hide in the darkest areas (which explains why Uncle Grimmly only appears in the blackout), and prefers to be in rooms with mirrors. E. Gadd also says that Uncle Grimmly is old for a ghost, even though Vincent Van Gore (age 59), Shivers (age 72) and Nana (age 76) are all older than Uncle Grimmly, who is 45 years old, by at least a decade.

Uncle Grimmly's only attack is wailing his arms, in an attempt to scare his victims, but this does no damage. Uncle Grimmly's heart quote states that others are afraid of him.

History
During the mansion blackout, Luigi goes into the Wardrobe Room and finds Uncle Grimmly there. This ghost guards the Key to the Breaker Room, which is locked during the blackout because it is where Luigi can restore the electricity to the mansion.

In the Wardrobe Room, Uncle Grimmly stands in front of the mirror but faces away from it. When Uncle Grimmly wails his arms, he becomes vulnerable to the Flashlight, and Luigi can vacuum him up with the Poltergust 3000.

After Uncle Grimmly is captured, the Treasure Chest with the Key to the Breaker Room appears.

Trivia

 * Uncle Grimmly might be Chauncey, Henry and Orville's uncle, and either Neville's or Lydia's brother. He is much closer in age to Neville (3 years older) than to Lydia (11 years older), so it's more likely Neville. This continues the tradition of a Portrait Ghost family that resides in rooms around the first area. His Game Boy Horror biography may further prove this fact: "[...]he tends to keep to himself, which suits the rest of the family just fine".
 * Uncle Grimmly is the only Area Four ghost that resides in a room from Area One.
 * He may be from Yorkshire as one of the things he says is "By gum."
