Lincoln decides to do the grocery shopping for his mother, but when his sisters (except Lily) tag along, they make his shopping experience difficult.
The episode begins with Lincoln watching TV while eating a bowl of cereal. Suddenly, a TV announcement is presented showing a new cereal called "Zombie Bran". Excited, Lincoln runs towards Rita, who is unclogging the kitchen sink, and asks her if they can get the new cereal. She denies, telling him that they have a very tight budget and that also they have a very big shopping list so there's no money left for treats. But Lincoln convinces her saying that he can do the shopping and still have enough money for Zombie Bran and while he does that, she can do all the things she wants to during her free time which she agrees to. As Lincoln prepares to go shopping, he is stopped by his sisters who want to accompany him. He tries to get rid of them until Lynn says that they will help him to shop, so Lincoln accepts and all of them (except Lily) go shopping.
At the supermarket, the Loud kids are warned by the supermarket's manager. If they get caught making a mess, they'll be kicked out. Lincoln then begins to find all the products of the shopping list taking only the products that are half priced or in offer, but during his path he is forced to stop his sisters' antics and avoid being caught by the manager.
Later, Lincoln manages to find all the products on the list and manages to leave enough money to buy Zombie Bran. But when he's going to grab the last box of cereal, another kid (who wears similar clothes like him) takes it and mocks Lincoln before running off to the cash register. Lincoln proceeds to chase him and at the same time avoid being caught by the manager. In the end, the manager catches the bratty kid and kicks him and his mother, allowing Lincoln to finally get the cereal.
After that, he brings all of his sisters to the cash register to pay for all the stuff he bought. They ask him why he is in such a hurry and he says that he's too close to obtaining his cereal thanks to the deal he made with their mother, making all the sisters begin to argue about it and subsequently begin fighting. During the brawl, Lincoln is pushed towards a stack of cans accommodated by Bobby, dumping all of them to the floor. The manager then kicks out the siblings without their purchases. Rita picks them up back to home and says to Lincoln how disappointed she is because he couldn't do the shopping, making his sisters feel guilty and sorry for him for their reckless actions.
The next day, Lincoln is watching TV at his house while eating the same boring cereal alongside Lily, feeling sad about what happened yesterday. After seeing another Zombie Bran announcement and turning it off, his sisters enter the house imitating a horde of zombies. Lincoln believes it's a joke, but then he's glad to see they bought the cereal. They apologize to him, saying that it was the least they can do as it was their fault that he couldn't get it. In appreciation of what they had done, Lincoln imitates a zombie and then begins a food fight with his sisters using the cereal. The episode ends with Lily making a zombie sound towards the audience.
The episode takes place in February, as calendar on the fridge has 28 days.
On the fridge is a haiku with A+. It says: A house full of kids Mostly girls (except Lincoln) Chaos will ensue -M.F. This poem has been mentioned online before.
Rita's full face is shown for the first time in her spa fantasy, though her eyes are covered by cucumbers and she has facial cream applied.
This is the second episode where Lincoln doesn't speak to the audience. The first instance was in "House Music".
The farmer from the episode "Hand-Me-Downer" makes a cameo in this episode, as well as the athlete from the same episode.
When the siblings stop fighting after the manager tells them they are kicked out, they are in the same pose they were in "Slice of Life" when Lynn Sr. tells them to stop fighting, and in "Changing the Baby" (expect Lincoln) when the latter whistles to them when they were fighting over Lily.
Lily breaks the fourth wall at the end of the episode by imitating a zombie's groan towards the audience.
This marks the first time Rita appears in a episode without Lynn Sr.
This is the second time someone other than Lori calls Bobby "Boo-Boo Bear", in this case it was the manager.
In fact, the manager only refers to Bobby as "Boo-Boo Bear" and not once as his actual name (probably to mock him).
The bad things that the girls did in the store:
All of them: Taking away Lincoln's cereal after they didn't think it was fair that he was getting a treat; this got them all kicked out
Lori: Admiring Bobby's employment and stocking skills
Leni: Setting the lobsters and the grilled chickens free
Luna: Jamming on the PA
Luan: Juggling and balancing eggs
Lynn: Riding a shopping cart at a high speed
Lucy: Sculpting a cake monster
Lana & Lola: Fighting with produce hoses
Lisa: Sitting in a freezer to test for her cryogenic studies
Lily was the only one not to get in trouble with the Manager, as she did not go to the supermarket with her siblings.
The sisters (except Lily) promised they will help Lincoln with the shopping, but instead they just left him alone with this problem by running to create a huge mess.
The sisters should've explained to their Mom that it was their fault, not Lincoln's, for causing trouble in the supermarket and Lincoln was being serious. However, she probably wouldn't have listened to them either.
Karma: The sisters (except Lily) and the Bratty Kid were messing around in the supermarket so they were all kicked out.
You must be on your best behavior when you're in a public place.
Never act selfish and be considerate towards other people.
Next time, think before you act.
This is the second episode to use this moral, with the first being "The Sweet Spot".
Cereal Offender - The title of this episode is a parody of the phrase "serial offender".
Peanuts - The bowl in the title card has the same design as Charlie Brown's shirt.
