She doesn't know the definition for "hypothetical."

She says she found it. But by "it," she means her floral pump that she lost (not the money).
Later, when Lori complains that they found nothing (meaning they haven't found any money yet), she retorts by saying her aforementioned floral pump is not "nothing."
She thinks Lori turned into Lincoln and Lily turned invisible and complains that nobody tells her anything.
Note: This is the second time she thought Lily turned invisible.
She agreed to cover for Luna, Luan, Lucy, Lola, Lana, and Lisa, and gave the task of covering for them to Lincoln.
When Rita asks "Leni" about her spring cleaning, Lincoln imitates her and says as soon as she "finds her springs, she'll clean them".
While disguised as Leni and talking to Pop-Pop, Lana claims that she got an outfit for half-off, which was weird because half of it wasn't missing.
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.

After the Loud siblings 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 Loud sisters 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.
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.

When everyone was shocked that the Dowl was fake, Leni still kept smiling instead of being shocked like everyone else.
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.

Loni (her male counterpart) runs into the wall, thinking someone moved the doorway.
When the Loud brothers dogpile on alternate Lynn Sr. 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.

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.
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 Loud 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.

However, since Lincoln was the only one communicating with Clyde, it is possible that she was unaware that Clyde was making a meal.
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.
Possible: When Lynn tells Lucy to not talk to Rocky about mortality, Leni follows with "Or death", even though death and mortality mean the same thing.
Possible: Leni explains that Lucy will be the "Future Mrs. Rocky" instead of "Future Mrs. Spokes", although this could be due to not knowing his surname.

Her "life's work" is a six-piece children's puzzle.

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.
Lincoln tells her 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.

Possible: She unknowingly spoiled the winner of the baking competition Lincoln was watching.
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.
She could, however, have written an incorrect detail about herself.
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.
Possible: Not mentioning the ad for the clown camp sooner, when the Loud siblings are thinking of ways to avoid Luan's pranks on April Fools Day.

She falls victim to an invention of Lisa's that hypnotizes mice, which are easily fooled because of their miniscule brains.
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.
When Lincoln tells his sisters his plan to get their parents into shape, Leni wonders what kind of shape he means, such as a triangle or a "circle thingy."
Possible: Her idea of working on triceps is folding T-shirts.
This is debatable, since Lynn Sr. claims it works.
When Lynn Sr. and Rita wanted her and Lori to take SAT prep classes, since it's the best way to get into a good college, she 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 Louds were 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.
After taking SAT prep classes, she and Lori announce that their verbal scores in their practice SATs went up 200 points. Leni adds that hers is 200 now, implying that it used to be 0 and she was thus completely illiterate beforehand.

Although, she might have done this intentionally due to being worn out from maintaining the deception, and realizing that being honest with Lynn was ultimately more worthwhile.
Possible: At the beginning of the episode, it was established that flushing the toilet would raise the water temperature in the shower. She, however, forgot about that, and unknowingly scalded Luna during the latter's shower.
However, she could have deliberately done so to show Lori how Luan isn't her usual jokey self.
Lincoln tells her sisters 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.
As established, she keeps spoiling surprise parties for whoever the surprise party is for.
This must because she doesn't know surprise parties are kept a secret and she doesn't know that secrets can't be told.

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.

In that same flashback, Lori had already explained golf scoring to Leni and proceeded to do so again.
Possible: She asked Lori for her phone back so she could like Carol's picture.
When Lori says that cute, lovable animals are her middle name, Leni misunderstands the turn of phrase and says that she thought Lori's middle name was Marie.

She could be referring to a headache weaker than Lori's.

Her idea of a vampire-themed snack is garlic bread, even though vampires hate garlic.

When Rita asks her to put a leaf in the table, she put an actual leaf on the table instead, most likely due to mishearing it as putting a leaf on the table.

When Ms. Carmichael gives Leni the clipboard, Leni asks if she wants her to read the name of who's in charge off of it, not picking up on the hint that Ms. Carmichael is leaving her in charge.
Possible: She takes the mannequin Tanya out for dim sum.
Possible: In order to distract him, Leni offers Lincoln to take him to Gus' Games 'n' Grub by claiming to have found money in her purse, which was actually just buttons, bottle caps, and washers. When Lincoln asks her if it is money, she nervously says "Yes".

According to Lincoln, Leni has mistaken objects for money before.
