After noticing that none of his sisters share his interests, Lincoln tries to mold Lily into his mini-me.
At the Loud House, Lincoln tries to ask his sisters if they would like to engage in some of his favorite activities. He asks Lynn if she wants to read comics, Luan if she wants to watch a sci-fi movie, Lola if she wants to collect coins, Lucy if she wants to go ghost hunting, Lana if she wants a peanut butter and sauerkraut sandwich and Leni if she would like to play video games. However, they all refuse, giving him specific reasons as to why they won't join him. This makes Lincoln explain to the viewers that none of his sisters share the same interests as him. However, when he sees Lily playing around with one of his video game controllers, Lincoln gets the idea to mold Lily into his liking. At that moment, Clyde arrives, asking Lincoln if they want to hang out together, but Lincoln denies, saying that he has other plans.
Throughout the day, Lincoln tries to mold Lily by making her like the things he likes, like coin collecting and building models. When that doesn't work, Lincoln resorts to hypnotizing Lily by attaching pictures of Ace Savvy on a mobile and spins it around, successfully making Lily like things Lincoln likes. Lincoln and Lily proceed to spend the day doing activities together, ending it with a game of chess at the park. As they leave, Lincoln tosses out Lily's blanket, believing she doesn't need it anymore. Unbeknownst to them, Clyde has been spying on them, coming to the conclusion that Lincoln is actively trying to replace him as his friend. Back at the house, as Lincoln and Lily (now donning one of Lincoln's polo shirts) play video games, the sisters arrive and ask what he's doing. Lincoln explains that because none of them want to do the things he likes, he taught Lily to like him, causing the sisters to look on with pure shock. Once night time comes, Lincoln reads an Ace Savvy comic to Lily as she sleeps, and he leaves, proclaiming that their friendship will last a long time.
The next day, Lincoln attempts to spend another day with Lily, but to his horror, she's not in her crib. He realizes that the sisters are attempting to copy what Lincoln did, having been inspired by his plan, ranging from:
Lynn using her to play baseball
Luan using her as a ventriloquist dummy named "Lil-Lil"
Lucy trying to get her to convert to goth
Lori trying to get her to watch her TV shows
Leni wanting to show her some fashion magazines (only to get "stuck" in Lily's crib)
Lisa using her as the subject of a dangerous invention
Luna making her a band mate (and nearly crushing her during a stage dive)
Lola using her a member of her tea party and Lana wanting to show her pets
Eventually, each one of the siblings attempts to run off with Lily, making all of them get into a giant fight. Suddenly, Lincoln tells them to stop, saying that they all have the same intentions, but that there's only one way to settle their argument: let Lily choose who she wants to hang out with herself.
In the living room, the siblings agree that whoever Lily crawls to, they get possession of her. They each pull out their respective belongings, and begin to bait Lily with them. However, as Lily becomes more and more stressed of her siblings' bribery, an angry Clyde barges in, still thinking that Lincoln is replacing him with Lily. Clyde tries to win back Lincoln by dressing up as a baby himself, much to everyone's shock. To everyone's astonishment, Lily crawls over to Clyde, where she grabs the blanket he's holding, revealing it's hers. Seeing Lily cuddle with her blanket, Clyde, unable to resist Lily's cuteness, hugs her. When Lincoln questions why Clyde's wearing a diaper, he explains that he thought he was trying to replace him, but Lincoln says that he would never replace Clyde. When Lincoln sees how happy Lily is with her blanket, he realizes that he and his sisters can't mold Lily, since she already has her very own interest, which is her blanket. When Lincoln asks Clyde if they want to hang out, Clyde declines, wanting to spend time with Lily more.

It is revealed that Lincoln's favorite sandwich is peanut butter and sauerkraut.
This episode shows that not only do none of Lincoln's sisters have anything in common with their brother, but they also have nothing in common with each other.
Tokusatsu - Ace Savvy’s spade motif is similar to Spade Ace from J.A.K.Q. Dengekitai and the titular character of Kamen Rider Blade.
Leni states that she doesn't like to play video games, despite the fact she didn't seem bothered playing one in "Driving Miss Hazy." She also plays video games with both Lincoln and Clyde in "Change of Heart."
Lucy refused to join Lincoln in ghost hunting, despite this she had no problem with this in "Suite and Sour."
The latter may be due to the fact that Lincoln asked her to hunt the ghosts in the house, whom she calls her "friends," while in "Suite and Sour" she is in an hotel she never has been before and, thus, she helps him because they would be hunting a ghost she never "met," meaning that she refused not due to not liking ghost hunting, but because she didn't wanted to hurt ghost she "befriended."
When Lincoln, Luan, and Lynn fought, from the smoke of their fight, body parts of other family members that did not participate in the fight were seen:
When the sisters fight for Lily in the hallway, Leni's sunglasses are seen falling off, but when Lincoln stops the fight, her shades are back on her head.
In that same scene, one of Lincoln's legs is seen in the fight cloud, even though he was not fighting with them.
Lynn and Lucy share the same room and have two separate beds, but when Lincoln visits them alone their beds are in the same place. The scene with Lucy was probably reversed.
When Lincoln breaks the sandwich in half for Lily, Lincoln's half has an bite on it, but, after Lincoln and Lily do a toast, and, when Lincoln bites the sandwich, the bite is gone.
Also, on the same scene, the crust is the same color as the bread.
Lori is not seen coming into Lincoln's room for Lily, when he looks for an orange shirt.
Lisa is not seen walking into her room, while Lincoln and Lori take Leni from Lily's crib.
When Lincoln was giving Lily a bedtime story, one of her feet is missing.
Luna couldn't walk into Lisa's lab unnoticed, as Lori, Leni, Luan, Lynn, and Lucy were guarding the door and window in this room was whole time closed.
Lisa pointed Lily is missing, despite not looking at her.
In the Latin American Spanish dub of the episode, Lana's line "Dang it!" is muted.
