History Funny / LuigisMansionDarkMoon

-->'''King Boo''': Why, if it isn't my old pal Luigi! Or is it Baby Luigi? I can't tell the difference.

--> '''E. Gadd:''' I completely forgot about him! ...[[HeelRealization I must be really]] [[TookALevelInJerkass horrible to work for]].

-->'''Luigi''': No no no, bad doggie!

-->'''Paraboola''': "I'm Paraboola! [[GeniusBonus A symmetrical open-plane curve formed by the intersection of a cone with a plane parallel to its side!]] [[MoodWhiplash I mean...]] [[GivingUpOnLogic BOO]]!"

* The game's introduction to the Boo enemies. When you reach the Dining Room, a scene plays where a Boo makes the table disappear and disappears. When Luigi makes the table reappear with the Dark-Light device, the Boo returns with a confused look. The Boo then [[https://i.ytimg.com/vi/d-yM4NB5qOU/hq720.jpg?sqp=-oaymwEhCK4FEIIDSFryq4qpAxMIARUAAAAAGAElAADIQj0AgKJD&rs=AOn4CLBPXXTEYT2tszHtydzLCkcU-RwnTA scowls]] towards the screen and vanishes in anger.

* The Fuzzballs in the Secret Mine's Chalet are adorable little nuisances, being walking (and rolling) balls of fur with mouths who get in Luigi's way. If you use the Poltergust's exhaust on them, [[FluffyDryCat their fur poofs out into a fluffy mass]].

* A cutscene of Luigi being pixelated in front of the Old Clockworks and in Treacherous Mansion that you can get by chance has him being pixelated without his hat. He starts freaking out looking for it, then the hat simply pixelates on top of his head.

-->'''Paraboola''': "I'm Paraboola! [[GeniusBonus A symmetrical open-plane curve formed by the intersection of a cone with a plane parallel to its side!]] [[MoodWhiplash I mean...]] [[GivenUpOnLogic BOO]]!"

-->'''Paraboola''': "I'm Paraboola! A symmetrical open-plane curve formed by the intersection of a cone with a plane parallel to its side! [[MoodWhiplash I mean... BOO]]!"

* In the Haunted Towers' first mission, there's a hole, where if you peek through it, you'll see [[spoiler:a Slammer ghost banging wildly on a pipe organ. A Hider later takes up residence in said organ during the second mission, and occasionally pops out of the pipes as the Slammer keeps playing it!]]

* The boss of the second world is a Possessor ghost possessing [[spoiler:''[[MundaneMadeAwesome a wooden staircase]]'']].
** Also hilariously appropriate, considering the area immediately previous to that. One's reaction may be something among the lines of "[[spoiler:That staircase was even worse than the one in VideoGame/SuperMario64! [[TemptingFate I never want to see another staircase agai]]-[[YouHaveGotToBeKiddingMe OH COME ON!]]]]"

* At the end, [[spoiler:when the Dark Moon is restored, all the ghosts are shown changing back to normal. Among the ghosts shown is a Slammer chewing on a Greenie's head. When it realises what it was doing after changing back, he spits it out before [[Heartwarming/LuigisMansionDarkMoon giving it a hug]].]]
** Also, right before that, [[spoiler:a Greenie in an outdoor area of the Secret Mine turns back to normal... and then starts shivering from the cold]].

* In the final battle with King Boo, in certain stages, he'll slam himself into the ground to have steel spiked balls fall from the air. As much as the fight is awesome (and slightly terrifying), [[spoiler:it's funny as hell to see one of the balls [[AnvilOnHead fall on him head-on]] if you're staring at him just as there's a [[ShadowOfImpendingDoom shadow]] growing larger, right over him]].

* In E-3, the windows in the Treacherous Mansion's east and west wings show ominous views of the mysterious curved object [[spoiler: which turns out to be the base for a portal]] on the Terrace. Peek into the window just outside the Terrace, however, and you see a Boo sliding up and down the curve like it's a skate ramp. A second Boo in the background flies over to investigate, only to fly into the path of the sliding first Boo and it gets accidentally smacked in the face. The second Boo gets upset and [[DisproportionateRetribution angrily rams into the playful one a few times]], and the poor playful Boo flies away, dejected.

* The scene where you extract [[spoiler:Mario]] from the painting. He just can't seem to catch a break when it comes to that kind of rescue. [[spoiler:To clarify, because there is no solid ground for Mario to stand on as he is extracted, he just ends up unceremoniously faceplanting on the ground below him, even though Luigi is standing literally right next to him and could have easily caught him.]]

* The Space Exhibit in the Treacherous Mansion has a telescope that reveals a cluster of asteroids and planets that the room is based on. Later in the mission, the Strong Poltergeist will flee into the West wing, and the Space Exhibit is where it ends up. Check the shaking telescope, and you see ''the Poltergeist sitting on the asteroid in space'', taunting you! The surreality of it has the ''WesternAnimation/LooneyTunes''- esque implication that the Poltergeist jumped through the telescope to get there. [[spoiler: To say nothing of the fact that you're sent there with him the second you exit the telescope view, and return to the exhibit once the fight ends!]]

* In one of the missions in Treacherous Mansion, Luigi can peek inside a hole near the balcony to find two Boos using the unfinished [[spoiler:portal]] as a skateboarding ramp.

* In A-3, once you enter the northern section of the Gloomy Manor, you come across some Greenies...and interrupt their game of rock-paper-scissors.

* Whenever you use a key, it just disintegrates, to explain the InterchangeableAntimatterKeys trope. However, prerelease materials showed a different justification: The locks were originally going to ''eat'' the keys.

* Just before sending Luigi into the Gloomy Mansion for the first time, Gadd tells Luigi to stop looking so scared because it's "just a few harmless ghosts." Then, Gadd thinks about what he just said and admits that it's actually several hundred dangerous ghosts.

* There's an EasterEgg where if Luigi stands under flowing water of some sort, he'll start scrubbing his pits with his hat and whistling.
