"It's a Loud, Loud, Loud, Loud, House" is the twenty-sixth episode of The Loud House.
When Lincoln and his sisters find a letter from the original owner of the house that reveals that there's a large stash of money hidden in their own home, they go on a frantic search to find it.
In the Loud House, money is hard to come by, so any amount of money is seen as precious. When Lincoln finds a quarter between the sofa cushions, his sisters fight with him to get their hands on it. Mr. Loud calls a halt to the fight, and makes the kids clean the attic as punishment for their greed, and roughhousing for money.
While cleaning, Lincoln discovers a letter that claims to have been written by the previous owner of the house, Sharon DeMonet, who claimed that her family always fought over money, and that she has hidden a stash of money for the finder of the letter to locate. Lincoln tells his sisters of the letter, but they don't appear to believe his claims of the hidden money. It turns out they did believe it, and they begin searching the house to find it. When Lincoln finds out, they brawl once more, and Mr. Loud tells them to stop fighting, and finish cleaning the attic.
Back in the attic, Lincoln re-reads the letter and decides to follow a potential clue by looking in a mirror. Sure enough, he finds a second letter in the reflection, which reveals another letter from Sharon DeMonet. Lincoln reads the letter, and says that to find the next clue, they need to "get to the bottom of the matter". This causes him and his sisters to rampage through the house, searching every nook and cranny as a hopeful spot for the money (though when they notice Lily napping while searching her and Lisa's room, they take an extra precaution of keeping their fight/search as quiet as possible). Upset that they haven't found anything yet, the sisters attack Lincoln to get the letter, believing it contains another clue that Lincoln left out. However, their struggle to retrieve the letter only results in them ripping it into nine pieces.
As the kids begin to complain that their clue to finding the money is destroyed, Lincoln snaps some sense into his sisters by reminding them that if they keep on acting like this, they won't get any closer to finding the money. Realizing that he's right, the sisters decide to bury the hatchet, and promise to work together from now on. Lily walks in to the hallway, having woken up from her nap, and they find an envelope taped to her diaper. Inside is a map that tells them where the treasure is hidden. They follow the map and it leads them to a big, red "X" in the backyard. Lincoln and Lucy dig it up (with the extra help of Lana) and they find a suitcase containing $500, which they split evenly, for all eleven of them, meaning that they each get $45.45.
Back in the house, the Loud parents watch their kids celebrate their discovery outside. It is revealed that Mr. Loud invented the whole "Sharon DeMonet" charade to teach his kids to work together and share, and that the money they found was his work bonus. But since his plan ended up causing so much damage around the house, Mrs. Loud forces him to clean it all up. As he cleans the attic, Mr. Loud tells the viewers that he is glad his kids are sharing the money, and how in their house, there isn't a lot to go around. Afterwards, he ends up finding a dime, but when he goes to pick it up, he accidentally hits the loose floorboard that Lincoln hit earlier.
The character's positions on the title card resembles one of the show's promotional images. The only differences are, aside from the added money, Leni and Luan have switched places, as well as some of the characters having angrier expressions, and Luna's teeth not showing.
This, along with "Sleuth or Consequences", and "The Sweet Spot", are rare examples of Leni and Luna (as well as the other sisters) being mean towards Lincoln for absolutely no reason at all.
The name "Sharon DeMonet" is a portmanteau of "sharing the money".
This episode reveals that Lana is an excellent digger, and Lucy has experience digging holes, referencing to their respective personalities.
It is revealed that Leni has a hairpin in her hair, which she can use to pick locks.
Lincoln and Lisa were the only siblings who searched for the money on their own.
This is the fourth time (so far) that Luna has been asked to provide a theme song for an activity.
It is also the first time Luna has used an acoustic guitar to provide background music, and the second time she has done so for a sibling other than Lincoln.
This is the second time she has done something for her sisters, which she does for Lana and Lori.
Although the Loud kids each get $45.45, multiplying that by 11 actually equates to $499.95, resulting in five cents (a nickel) being left over. It's unknown what was done with the remaining nickel, either someone kept it or they threw it away.
It was also strange to see Lily getting money, since she is just a baby, and babies don't understand money.
Nor did she have to go through what the others went through.
This is the first time that Lisa's glasses crack.
This is, as of now, the episode with the longest title.
When Leni uses one of her hairpins to open the case, she remarks "there's more to my head than just air", which seems to imply that she is aware that she is not very bright and/or smart.
Leni suggests to split the quarter 40/40, like she said about the last pizza slice in the short "Slice of Life".
Lily is the only sibling not to get involved in the money search, most likely because she was napping (as well as the fact that she is still just a baby).
Ouija - When Lucy is trying to contact "Sharon DeMonet's spirit", she was using a talking board, or better known as an Ouija.
Morgan 88 - When the kids are in the attic for the second time, Leni is holding a box with a label which says "Morgan 88", a reference to a building in Jersey City, NJ. It also could be a reference to Jared Morgan, a prop designer of the show.
SpongeBob SquarePants - When Lori and Leni screamed at the fake skeleton, the music that plays is the same as the one in the episode All That Glitters, when Mr. Krabs told SpongeBob to get a new spatula when his old one broke.
Sherlock Holmes - Luan calls Lincoln "Sherlock", a fictional private detective.
After searching in Lisa and Lily's room, the former's glasses are cracked on the left side. Later, when they rip the letter, Lisa's glasses are cracked on the right side.
When Lynn Sr. mentions the dark corner in the attic, Leni doesn't have her sunglasses.
As the siblings attack Lincoln to get the letter, Lori's right foot is bare, and she still has her shoe on her left, but when they argue after ripping the letter, Lori's left foot is bare, and her right foot is not.
Before Lola said that she's practicing for the "Little Miss Chimney Sweep Pageant", her eyelashes are missing when she closes her eyes.
Before Lana digs down to find the briefcase, her eyelashes are gone.
They were also gone while she and the other siblings were cheering in excitement about finding money.
In the Latin American dub of the episode, Lincoln's line "Oh, Lola" was replaced by the line "Entregamelo, mortal" ("Give me that, mortal", said by Lucy).
When Lana says "it's mine", she sounds almost like Lola.
