King Boo's Illusion

King Boo's Illusion is the final place visited in Luigi's Mansion: Dark Moon, and here is fought King Boo, as the final boss.

Apon defeating the Tough Possessor, Professor E.Gadd tries to pixelate Luigi out, to meet him in the Bunker. However, the transmission is intercepted by King Boo, and Luigi lands in this place. King Boo then starts taunting Luigi and by making windows visible, where the player can see King Boo's silhouette outside. After the taunting, Luigi looks behind, only to see Mario trapped in a painting. He reaches out, but King Boo appears behind the painting, and swallows it. He then starts speaking to Luigi, about his incarceration in a painting and about his escape. He then announces that "he will repaint the town red". He then accumulates energy from his crown, and creates the arena for Luigi and King Boo to battle.
