Left in the Dark

 * Possible: Lincoln tries to get to the T.V. and shouts to Leni. She thinks there's a spider on her, and frantically rubs her head trying to get it off. Then Lincoln says there's actually a zit on the end of her nose. She runs off thinking she's a hideous monster.
 * When the lights go out, Leni thinks she has gone blind.
 * She thinks someone is touching her hand when she is actually touching her own hand.

 * When Lincoln says it's not a boy, she asks if the bully is a dog.
 * She believes Lincoln's lie about trash can lids being "all the rage right now" and wears one as a hat.

Making the Case

 * She continuously walks into walls: one time when Lincoln's filming her, and the other time when she tells him she refuses to speak to him ever for his video.

Driving Miss Hazy

 * When Lori tells her to make her bed because she needs a ride to the mall, she thought Lori meant it literally, and constructs a bed.
 * She failed her driving test 12 times, one of her failures included crashing Vanzilla into a tree, and setting a fire hydrant to spring a leak, with a nun screaming at the top of her lungs in a panic, and a paper boy hanging by a branch.
 * When she goes to the DMV to take her driving test, she goes the wrong way.

 * She does not know how to drive a lawnmower, and drives through the hedges.
 * She has no knowledge about car parts or their location.

 * While listing off all the places Leni could have driven her siblings to, she mentions the mall twice.

 * She reminds her teammates that they are trying to coax Lincoln to vote for Aloha Beach when they were pretending they aren't.
 * When Lori says the sodium hydrochlorite plan "has Lisa written all over it", Leni thinks that the label is how Lisa's name is spelled.

Sound of Silence

 * Possible: When she comes to get Lincoln to help her with her "Manotard" design, she reminds him that they talked about it "tomorrow" and immediately corrects herself by saying "yesterday."
 * This could be a natural slur of speech as evidenced by her immediate correction.
 * She doesn't know the definition for "hypothetical."
 * She accidentally calls Lincoln "Landon."

Space Invader

Picture Perfect

 * When Lincoln tells Leni to move to the left, she moves to her right, thinking she meant his left.
 * She thinks a solar eclipse is happening when her shades drop over her eyes, and when Lincoln removes the shades, she says he's like a wizard, or a weatherman.
 * When Lincoln threw the ice packs and bandage, she and Lisa told him to throw them, even though he threw it already.
 * She says "And this glasses isn't I, either." which is grammatically incorrect.

Linc or Swim

 * She later says that there's ten of them and when Lucy corrects her, she tells her that she forgot Marco.

Changing the Baby

 * Whenever Clyde faints upon seeing Lori, Leni thinks there are peanuts in what she gave him.

Butterfly Effect

 * She thinks the hole in the wall caused by the chemical explosion is an extension to her and Lori's closet.

The Green House

 * She wastes water by running it and not even using it.
 * When Lincoln tells her to use a moist towelette to clean herself, she tells him she's showering and closes the curtain on herself even though she's fully dressed. Lincoln does this at the end of the episode as well.
 * When Lincoln takes the TV away, Leni picks up the remote and thinks their neighborhood is on TV.

Along Came a Sister

 * In a flashback, Leni thinks Clyde in his spider costume is a real spider.
 * This was presumably shown to show her extreme.
 * When the others try to hide Frank from her, Leni thinks they're planning a surprise party for her and even says she won't tell herself about it.

 * Leni tells the gang that they should split the quarter Lincoln found 40/40.
 * When she and Lori are looking for the money together, she mistakes a Halloween skeleton prop for the remains of Sharon DeMonet.
 * When Lincoln wonders what they are doing, Lori lies and says they're just cleaning below, but Leni blurts out that they're looking for the money.
 * Leni says she found it. But by "it", she means her floral pump that she lost (not the money).
 * When Lori complains that they found nothing (meaning they haven't found any money yet), Leni retorts by saying her aforementioned floral pump is not "nothing."

Cover Girls

 * When Rita asks "Leni" about her spring cleaning, Lincoln imitates her and says as soon as she "finds her springs, she'll clean them".
 * Leni runs into Luan dressed like her and does a mirror routine with her.
 * Leni says it was a pinky swear that they would get right back to their spring cleaning after they were done with their things, but holds out her thumb instead.
 * Possible: Leni (dressed as Lana) thought she was a victim of mistaken identity when Mall Cop Captain stopped her from trailing mud at the mall.

Attention Deficit

 * When Lincoln asks for help after Lana hogtied him, Leni comes back for him, apologizes, and carries him like a handbag instead of untying him.
 * Luna tells Leni to sing backup, and she sings the actual word "backup" as opposed to the actual lyrics. Then Luna tells her she has to sing what's on the page, to which she responds by literally singing "what's on the page."
 * During the family's performance, Leni walks backwards, claiming she is a "backup" dancer and falls off the stage.

A Novel Idea

 * During the girls' popgun fight, Leni has her gun aimed at her own face; Lisa changes its direction before she fires.

April Fools Rules

 * After Lincoln and the girls trap Luan in a crate, they make fun of her with crate-related puns. Leni made a joke saying, "You're in a crate!" and laughs at that, while the others just stare at her confused. Lincoln says that they should all go to bed.
 * When the other girls are hiding from Luan's pranks and run out of food thanks to Lana eating it all, they suggest to draw straws. Leni just concedes to going and sacrificing herself because she claims to be a terrible artist, meaning she would make a terrible drawing of a straw.
 * While Lincoln avoided Luan's kitchen direction arrows, Leni follows them to an undisclosed location, and thanks each and every one of them.

Cereal Offender

 * She tries to release all the lobsters from their tank, and the grilled chickens (even though they're already dead and cooked) from the rotisserie, because she does not want anyone to eat them.
 * While freeing the lobsters, she points to the direction to the ocean, then points the other way which is leading to more of the store.

Come Sale Away

 * She says to Lana, she could neither sell a dress if it was 50% off, nor even if it was half off, which is the same thing.

 * She mistakes Lily's blanket for numerous other things like a doormat and a napkin.

Roughin' It

 * She says she can wear her poncho for all five seasons when there are only four.

​Raw Deal

 * She believes that they're going to meet Pop-Pop at the park, because the park has a "geezer." Lincoln corrects her by saying that the park has a "geyser", not a "geezer."
 * She casts her fishing line in a bush.
 * When everyone was shocked that the Dowl was fake, Leni still kept smiling instead of being shocked like everyone else.

A Fair to Remember

 * When Lori needs a plan to get Bobby back from Lincoln, Leni suggests that she hang out with Ronnie Anne because she thinks Ronnie Anne would be like the sister Lori never had. Lori already has nine sisters by the way Leni meant it. It wouldn't be so dumb if she meant it the other way around though by saying that Lori would be like the sister Ronnie Anne never had.

One of the Boys

 * Her male counterpart, Loni, runs into the wall, thinking someone moved the doorway.
 * When the boys dogpile on the alternate universe's version of their dad and tell him to say "uncle," Loni says it's their dad.
 * Both Leni and Loni are easily fooled by Lincoln's lie that he is referring to nuns when he mentions sisters.
 * Possible: In the dimension where the brothers have a sister named Linka, when "Lincoln" is confused that the brothers are suddenly nice despite being bullies earlier in the episodes, Loni assumes that Linka wants him and the rest of the brothers to stay in her room until she falls asleep.

A Tattler's Tale

 * When everybody is complaining that Lola knows their secrets, Lynn thinks there's a rat (slang term for a snitch) in the group. Leni thinks Lynn was referring to a real rat, as she jumps in fear and asks where it is before Lisa corrects her by giving her the correct meaning.
 * When Lincoln realizes Lola was the true rat, he tells his sisters that her name rhymes with "granola." Leni presumes that Lisa was the rat.

Funny Business

 * She didn't throw the pie at Luan at a party because she was in the audience, making Luan throw the pie at herself.
 * She wrote her last name on the position.

Snow Bored

 * She misspells the words "fun" and "school" as "f-o-n" and "s-k-o-o-l" respectively.
 * When Lisa tells everyone that she can't stand to hear them spell erroneously, Leni thought they were still spelling "fun".

The Price of Admission

 * She believes Lincoln is talking about savings on shopping, when he says it's Daylight Saving Time; she then leaves for school.

One Flu Over the Loud House

 * When Leni checks Lincoln's temperature to make sure he isn't sick, she wrongly says that Lincoln's temperature is 986°F. She meant to say 98.6°F (37°C), the normal human body temperature.
 * While firing chicken noodle soup at the sick siblings, Lincoln warns Leni that Lori is at 9:00 (behind her). Leni tells him to make up his mind, asking what time it is, not knowing the contagious Lori is behind her.
 * When Lincoln says that she's starting to act like Mother Teresa, her rebuttal is that their mother's name is Rita, not Teresa.
 * She gets picky about the protective masks she could wear, even though the sick siblings are behind her.
 * When Lincoln tells Leni to duck after Luna sneezes, she thinks there's a real duck and asks if it's sick.
 * Possible: When Lincoln asks for the table, Leni wonders if he plans on making his sick sisters a meal, even though Clyde is already doing that.
 * However, since Lincoln was the only one communicating with Clyde, it is possible that she was unaware that Clyde was making a meal.
 * It also might've been possible that she thinks that the only way to cure the zombie flu is to give them a loving thing while the others think that the only way to do so is to shoot chicken-noodle soup to them from a gun. In fact, she doesn't know what the zombie flu is.

11 Louds a Leapin'

 * She continuously makes Christmas outfits out of her mother's decorations, mistakenly thinking they're her fabrics.
 * She even made a vest for Mr. Grouse from his curtains.

​Brawl in the Family

 * When Leni came downstairs wearing her new dress, she thought Lori holding her dress (which was the same one Leni bought) was a brand new mirror that was installed.
 * When Lincoln asks Lori and Leni how they resolved their fight over the dress, Leni says that Lori gets to wear it on any day of the week that ended with "Y", and she gets to wear it the rest of the time. In other words, Lori gets to wear it every day of the week (since the days of the week all end with "Y"), while Leni will never have a day to wear it.

​Suite and Sour

 * Possible: Leni might of been the one that spelt business center as "BISNES CENTER" when setting up for the play.
 * Leni finds a name tag with the name Fritz on it, and mistakes it for a souvenir pin.

 * Leni does not realize she was talking with Lily and her dad through the phone.
 * Leni does not realize she was expelling her own family from the hotel.

Back in Black

 * Possible: Leni tells Lincoln about Lucy's makeover, saying that Lucy will be the "Future Mrs. Rocky", instead of Rocky's surname, although this could be due to not knowing his surname.

Vantastic Voyage

 * When Lincoln comes up with a plan to get Lynn Sr. to get a new van, he suggests they use the subliminal approach. All the sisters agree, "Mm-hmm...", except Leni, because she didn't understand.
 * When Lori tells Steve that she and Leni would like to go for a test drive, Leni thinks that they're taking a test and tells Lori that she didn't study.

Cheater by the Dozen

​Lock 'n' Loud

 * Leni says her life's work is a six-piece children's puzzle.
 * When Lynn teaches Leni and Lola to fight a dummy just in case if a burglar broke in, Leni flirted with the dummy instead of attacking, claiming it looked cute. When Lola attacked it; however, Leni chastised Lola for attacking it, thinking "he" liked her.
 * When the Loud kids were cheering when Lincoln informed them that the burglar was caught, Leni still had feelings towards the dummy (which she named Donnie), and says that she and "Donnie" should've ran away to Mexico while they had the chance.
 * Leni claims she has a deadly spray to use against the burglar called "Fatal Encounter." However, Lori points out she's just holding a perfume sample.

​The Whole Picture

 * While going through Lincoln's childhood memories, Leni mentions the time when Lincoln accidentally deleted all of his childhood photos, despite Lola telling her that just happened that morning.

​No Such Luck

 * Lincoln tells Leni that he doesn't want to go her charity fashion show out of fear that his "bad luck" could make her trip, jam a zipper, or break a heel. Later, when Lana offers Lincoln to come to her alligator wrestling match, Leni intervenes, and tells Lana to reconsider inviting Lincoln, giving the same exact reasons Lincoln told her earlier (trip, jam a zipper, or break a heel).
 * Possible: When Lincoln can't come to the movies with the family because of his "bad luck", Leni says she'll tell him how the movie ends, which is a spoiler.

Kick the Bucket List

 * When Leni asks Clyde if he wants a partner to play with on the seesaw, Clyde denies the offer, saying that he has Lincoln (which is actually a rock with Lincoln's face painted on it). Leni, not noticing that it's not the real Lincoln, says hi to "him". Later, when the twins attacked Clyde for ruining their sandcastle, Leni, needing to go to the bathroom, asked "Lincoln" to watch the twins while she's gone.

Party Down

 * Leni tells Lincoln (who's in disguise) that she cannot let him in the party due to him not being on this list and informs her it's a shopping list. She gets upset that "feta cheese" isn't coming.

​Fed Up

 * Possible: She gave Lynn Sr. a 10 just for using skates to cut up hot dogs as if he was actually in a figure skating competition.
 * She hides the ingredients for Lynn Sr.'s goulash in his slippers and robe, leading to the parents discovering the kids sabotaging the meal.
 * When deciding on what dish to make for their parents, Leni suggests they make goulash. When Lincoln tells her that goulash is one of the dishes their father cooks weekly, and want to avoid it, which is why they're doing this, Leni claims that she misses it.
 * She broke the microwave oven.

Pulp Friction

 * She mistakes Lincoln and Clyde's comic book as a coloring book.

 * Possible: While taking the compatibility test, Leni remarks how she got one of the questions wrong, despite the fact that there are no right or wrong answers in a compatibility test.

 * Leni laughs at every little thing Luan says, which is evident when she began laughing hard when Luan said she needed to use the bathroom.

Spell It Out

 * Due to not being able to speak, Leni apologizes to Lucy for walking all over her by playing a game of Tic-Tac-Toe on Lisa's board.

Fool's Paradise

 * Possible: Not mentioning the ad for the clown camp sooner, when the siblings are thinking of ways to avoid Luan's pranks on April Fools Day.
 * When the family is voting not to open the door, she touches her ear instead of her nose, causing her to say in frustration that she always does this wrong.
 * Ironically, she did it right in "Suite and Sour" and "Potty Mouth", and Lincoln lost those times.
 * Possible: She says she would rather be stuck to the sign than fall victim to Luan's pranks, despite the fact that she has already been pranked.
 * However, what she possibly means is that she would rather be stuck than fall victim to Luan's other pranks.

Job Insecurity

 * She thought that her father got plastic surgery after seeing another man in his desk.
 * She also has to rely on a photo to identify her own father.
 * She held a leaf in front of her while hiding behind the window, despite being completely out of Lynn Loud Sr.'s sight.
 * While looking for a new job for Lynn Sr., after Lincoln said that a company was looking for someone who is good with Internet startup, Leni thought that someone already started the Internet.
 * Leni thought the Russian word nyet meant "yes." (It actually means the opposite.)

​Garage Banned

 * Leni says that Lori's lucky that she gets her own room, despite having her own room now (because of Lori's absence).
 * When Lana came into her room to tell her that she had a bad dream, Leni asks Lana what the dream was about. When Lana said that blood-sucking aliens were approaching her, Leni panicked, and started barricading her door with her dresser, believing that the blood-sucking aliens were real.
 * When Lori faked the garage being infested with mice, Lisa used her latest invention to hypnotize the mice, saying that they're easily fooled because of their miniscule brains. Leni, however, falls victim to the machine, due to her low intelligence.

Change of Heart

 * She thinks there are only forty states in America, instead of fifty. (Mr. Grouse also doesn't know the correct number of states, as he said there are 48 states. He may just be counting the Contiguous United States, hence excluding Alaska and Hawaii.)
 * She has difficulty passing the letter P in the alphabet.

​Health Kicked

 * Leni doesn't seem to know what a fecal study is.
 * When Lincoln tells his sisters his plan to get their parents into shape, Leni asks, "What kind of shape? A triangle, or more like a circle thingy?"

 * This is debatable, since her father claims it works.

Future Tense

 * When Rita and Lynn Sr. wanted Lori and Leni to take SAT prep classes, since it's the best way to get into a good college, Leni remarks "What about just using the front door?"
 * Because of that remark, Rita suggests they book Leni up for the double session, which could mean she needs twice as much education than Lori, due to her lack of intelligence.
 * While taking photos of Lori, Luan, and Lucy, Leni took a photo of them while Lori wasn't ready yet, due to her telling Luan that she was doing her duck face wrong.
 * When the Loud family was picking up trash on the interstate, Leni is unaware that her garbage bag has a hole in it, causing whatever trash she puts in to fall out, prompting her to put it back in, with similar results.
 * When Lori and Leni arrived home after taking their SAT prep classes, Leni, along with Lori, stated that their verbal scores went up 200, and Leni says her verbal score is now 200, meaning that her verbal score was originally 0 (which means she was completely illiterate beforehand).
 * This could explain why Leni wasn't able to say her own surname in "Suite and Sour," since she was reading it in a card.
 * Just like "Along Came a Sister", she thinks Luan's fake spider is real.

Lynner Takes All

 * When Lynn was gloating "Lynn-er, Lynn-er, chicken dinner!", Leni responds with "I thought we were having salmon."

 * Leni ruins the Louds' plan to throw the game, so Lynn could win by literally throwing the game board out of the window.

 * ​Possible: During the song, she referred to her closet organizer as "a closet thing."

 * Lincoln tells the siblings that Luan heard everything they said and she's giving up comedy. Leni thinks that Luan's show at the Chortle Portal will be really bad.
 * Leni does a spit take whenever someone talks, even if it's not a joke.

No Spoilers

 * As established, Leni keeps spoiling surprise parties for whoever the surprise party is for.
 * She thought Cliff was communicating with her by a series of synchronized blinks, when it was actually just a distraction.
 * She thought her siblings screaming was a new salutation.
 * She thought she farted when it was actually air escaping from a deflating balloon.
 * When Lincoln fell down the stairs after tripping on one of Luna's drums, Leni suggested Lincoln use parachute pants so he can get down safely.
 * Before heading off to the Hazeltucky Party Outlet to get Rita a birthday card, Leni thought she forgot her shoes, until she realizes she's already wearing them.
 * She thought a birthday card with a music-like theme was a musical card, when actually, her cellphone rang every time she opens the card.
 * Also, she thinks about making the 'card jingle' her ring tone, apparently forgetting that it was already her ring tone.
 * She accidentally spoiled Lynn Sr.'s upcoming surprise party when the siblings decided to make her their official party planner.

Not a Loud

 * Possible: She believed Lincoln was carried to the house by an eagle, even though the blanket he was wrapped in just had the presidential seal on it.
 * Then again, she was only five years old when Lincoln was born, so it makes sense that she does not recall every detail.

Tricked!

 * Possible: She wonders why the severed head of Marie Antoinette is so pale, and when Lucy explains that she was decapitated, Leni comments that she still would have put on some blush.

​The Crying Dame

 * When Leni made hair extensions for Lori, she states that she needs a stapler to attach them to Lori.
 * When feeding Lily, she says "Open the airplane, here comes the tunnel." rather than vice versa. That said, it should be a train, not an airplane, and she makes a growling sound.

 * Possible: When Lincoln says that Lynn Sr. has become them when they were using their electronics nonstop, Leni screamed in horror, assuming that Lynn Sr. transformed into one of them.

Snow Way Out

 * Leni uses a hair dryer to reheat a pot of goulash, instead of the oven, saying that she didn't want the goulash to get split ends.
 * Leni doesn't recognize the winning Burpin' Burger wrapper when she gets it. She thinks that it was a dirty wrapper.
 * When Leni opened one of the entrances in Burpin' Burger, she thought the snow blocking the doorway was a closet the restaurant had to store snow.

Tripped!

 * On the title card, Leni is oblivious to the danger present, and is more focused on taking a selfie.
 * She misspells fashion and doctor as "fashun" and "doctir" respectively on her fashion advice booth.
 * When Rita told Leni to imagine the hot heat as if she were on the beach, Leni says she cannot do that, because of the dress she's wearing.
 * Leni prepared egg salad sandwiches weeks before the vacation, even though eggs begin spoiling the moment they're cooked, hence why she and her family got sick after eating them.
 * Possible: When the family are shooting her dirty looks during the song and mentioning the egg salad gone wrong, she obliviously smiles, probably meaning that as a compliment.
 * She thought the prisoner's handcuffs were bracelets and unlocks them.
 * When the top half of Vanzilla was knocked off, instead of being scared that the family lost all of their luggage, Leni cheered at the fact that the van is now a "convertible."

Insta-gran

 * When Lincoln said "bingo" after completing the fabricated photo of Seymour and Myrtle kissing, she told Lincoln that Bingo doesn't start until 4:00.

​A Fridge Too Far

 * Possible: She mispronounces minestrone as "mine-strone."
 * This is debatable, as she says this intentionally, claiming that the minestrone is hers, and no one else's.

Selfie Improvement

 * In Lori's flashback of Carol winning the golf tournament, she cheered for Lori for having the highest score, when lower scores are better in golf.
