Episode Information

"Appetite for Destruction" is the forty-sixth (forty-seventh in production order) episode of the fifth season, and the two-hundred-forty-fifth episode of The Loud House.


When Lily starts misbehaving at home, Mom and Dad think her new preschool friends might be the cause.


Lily with a bad attitude.

The Loud family is having dinner at Lynn's Table. As everyone eats their plates of spaghetti, Lynn Sr. arrives asking his family if they want more parmesan cheese, to which they agree. When Luna asks her father why he's so pushy with the cheese lately, Lynn Sr. states that his pen pal in Italy has sent him countless wheels of cheese and couldn't get over how good they taste.

As a delivery truck delivers another shipment of cheese wheels, the family suddenly hears noises coming from the kitchen. They enter and discover it's Lily, playing on one of the wheels. Rita approaches her to tell her not to play on the cheese, when Lily suddenly reacts by furiously growling at her and nearly biting her. None of the kids state that they're responsible for Lily's bad behavior (though Lynn admits that she taught Lily how to burp the alphabet).

In the middle of the night, Rita and Lynn Sr. are woken up from noises in the kitchen. When the two enter, they discover Lily struggling to pull out a wheel of cheese from the fridge. Lily says she wants a snack, but when Rita and Lynn Sr. tell her it's not that time, she attacks them to stay away. Regardless, the parents proceed to put Lily back into her crib, and at that moment, they theorize that Lily's bad behavior might because of her preschool friends, who might be a bad influence on her. Lynn Sr. suggests spying on her to see for themselves, but Rita, fearing that Lily might know, decides on a second plan.

The next day, Rita and Lynn Sr. send Leni to Royal Woods Preschool to spy on Lily. During Leni's stay, she discovers that Lily's bad behavior seemingly stems from each one of her classmates. After presenting her findings to her parents (all while Lily makes a mess in the kitchen), Rita and Lynn Sr. fear that Lily's bad behavior will last as long as her teenage years and declare that they need to find a playmate for Lily who is a good role model.

Later, Rita and Lynn Sr. begin scouting around Royal Woods trying to find a playmate for Lily. After rejecting a biter at the store and a diaper thrower at the park, the two eventually spot a toddler named Aidan who has all the mannerisms of an upper-class gentleman. Thinking he's perfect, Rita and Lynn Sr. arrange for Aidan to spend a playdate with Lily. Sometime later, Rita and Lynn Sr. introduce Aidan to Lily and leave the two alone so they can spend time together. However, after only a few minutes, the two are alarmed by loud noises from upstairs and upon checking up on the two, they discover that Lily has completely trashed the room and has started fighting with Aidan. Eventually, an injured Aidan is picked up by his parents and they quickly drive away, as well as refusing Lynn Sr.'s wheel of parmesan cheese as an apology.

As the parents pick out the sticks and dirt in the parmesan wheel, the two eventually declare that they themselves are the reason why Lily's behavior is so bad lately. Suddenly, they hear noises in the living room, and when they check it out, they discover Lily fighting with Luan over her wheel of cheese. When they witness her having a cramp, Rita realizes the true cause of Lily's bad behavior: because she has eaten so much cheese, she has become constipated. Realizing this is the case, Lynn Sr. promptly bakes up "triple-bran fiber blast" chocolate chip muffins that, once Lily digests, causes her digestive system to act up, forcing her to rush to the restroom. Upon exiting, Lily, now feeling better, returns to her sweet demeanor.

Now it's Leni who has a bad attitude.

Sometime later, as Lily has a nice calm playdate with Aidan and another classmate, Lynn Sr. tells Rita that he managed to convince Flip to take all the excess cheese off his hands (and made cheese flavored Flippees as a result). As Lily shows off a drawing of a horse she made, Leni, who is revealed to be playing alongside Lily, gets angry, as she was drawing a horse as well. Seeing her get angry, as well as her digestive system acting up while eating a cheese sandwich, the parents fear that Leni may too be constipated, prompting Lynn Sr. to run to the kitchen to make more muffins.
