CJ, Fenwick and Crispo win a sleepover at Pootatuck, along with several other students. Despite previous failed attempts, the three are determined to stay awake all night and witness the sunrise, but Principal Hader tries everything she can to make them go to sleep, so that she won't have to deal with the children. Meanwhile, CJ's parents unsuccessfully try to break into the school to give CJ her retainer, despite the fact that the school's doors will not open until the next morning. Her brother manages to break in on the emergency door and give them things to stay awake. In the last moment, Hader catches CJ and her friends, but they manage to see the sunrise and then immediately drop to the floor and fall asleep.

CJ wants a pet guinea pig, but her mom thinks she's not responsible enough, since she couldn't keep any of her pet fish alive for more than 2 weeks. To prove to her mom that she is responsible, she agrees to adopt a "flour baby", which is just a bag of flour (Crispo also gets one and Fenwick gets a bag of chips, since he is allergic to wheat). This becomes the next thing on their list. Things start out okay, but eventually, it spirals out of control. CJ loses her flour baby and she enlists Fenwick and Crispo's help to help her look for it. Mindy volunteers to help Crispo take care of his flour baby and he eventually agrees, since he wants to beat Fenwick. Crispo and Mindy act like parents, even going so far as to have a custody agreement over the "baby", but they argue regularly. The vending machine in the teacher's lounge is out of a certain type of chips and Fenwick happens to have a bag of it (his "flour baby"). So, the teachers hunt him down and try to get him to give them the bag.

CJ and her friends decide to change their looks to see what happens. Crispo wears all red, which becomes a problem when a fire chief is looking for him after he burned down the earth day tree. Fenwick wears a muscle suit that lands him a spot on the wrestling team, a position he is not prepared for. And CJ wears a "power suit". The suit gets her a position in which she works with the principal and tries to find out who keeps vandalizing the school's posters.

The group decides to enter the science fair, but CJ cannot figure out what she wants to do and starts losing her spirit; however, Ronbie raises her spirits back up with a pep talk. Meanwhile, Fenwick builds a robot that is beaten by Mindy's better robot. Crispo tries multiple things to impress one of the judges, but repeatedly fails. Eventually, CJ figures out that she can enter her list of 100 things to do before high school because of the science of whether or not things on the list prepare someone for high school and Fenwick builds a robot that highly surpasses Mindy's, but it goes haywire and wrecks everyone's science fair projects, except Crispo's, whose science fair project ended up being himself because of what his body can do. Back at home, CJ notices the trophies that she got from her brother, such as "Greatest CJ Martin Ever" and "Outstanding Achievement in Sisterhood".

When Crispo joins the Save the Baboons club, which is run by Mindy and Blake, CJ and Fenwick, who were not allowed to join, try to find their own clubs. Fenwick joins the Super Genius club and CJ joins the Club club, which is boring. CJ and the other club members attempt to make it cooler, but it gets taken over by Mindy and Blake's club, so CJ tries one more time in a bigger room. When Crispo discovers that the money donations for the Save the Baboons club is going toward the club's expenses rather than saving the baboons, he leaves and join CJ's Club Awesome club, which becomes a huge success. However, it becomes too much of a success after Mindy's not able to go in, despite everyone being able to join, and CJ, Fenwick, and Crispo not even being allowed to go back in due to the club reaching capacity.

Due to a bad childhood experience, Principal Hader cancels the Halloween carnival. CJ, Fenwick, and Crispo make it their thing to figure out why Principal Hader hates Halloween and fix it. Meanwhile, Crispo is made fun of for wearing what others perceive as a costume for little children. He then changes to a more dark costume to be cool, but later realizes that he should not change simply because somebody doesn't like a particular feature about him. Later, CJ learns that when Principal Hader was younger, she wanted to be an alien for Halloween; however, her mother forgot her costume and her father made a quick costume by making holes in a pillowcase, causing her to be laughed at. CJ, with help from Mr. Roberts and other staff, makes a costume for Principal Hader, which she is extremely grateful for; as a thanks, she calls the Halloween carnival back on.

CJ, Fenwick, and Crispo are all sick; CJ and Fenwick are both home while Crispo wants to know what it's like to have a sick day, but his parents don't ever allow him to stay home, no matter how sick he is. Meanwhile, to keep his perfect attendance record, Fenwick has Crispo walk around with Fenwick on an iPad. Later, Fenwick gives Crispo the idea to get on a bike and go over to CJ's house to make the best of his sick day, but when Crispo gets over there, CJ's not there because she came back to school since she was feeling a lot better thanks to some disgusting green liquid medicine her parents forced her to take earlier. Then Crispo is almost caught when CJ's mom stops by to check on CJ because an appointment was canceled. Since Crispo was already on the phone with CJ, he puts it on speaker and he and CJ manage to fool CJ's mom. Meanwhile, Fenwick's iPad battery is dying and CJ must get him to his last class in order for his perfect attendance to stay. Elsewhere, Crispo discovers on the school website that the bike he borrowed is a police bike, which is thought to have been stolen. Then CJ gets a text from her mother that she's coming back early and she must run back home or else she and her father will be in big trouble. In the end, Crispo gets the bike back without being noticed and CJ makes it back home in time, but due to all the running, she gets a fever and is home sick for four days.

When CJ, Fenwick, and Crispo's current lunch table begins to fall apart, they all locate a different table to sit at. CJ joins Mindy's table and subsequently aids Mindy in finding her mom's ring that she lost, Fenwick pretends to be an eight grader in order to enjoy the eight grade patio, and Crispo joins the Swords and Stones table. While CJ and Mindy are retracing Mindy's steps to look for the ring, Mindy remembers that she took it off to wash her in hands in the bathroom. Unfortunately, Principal Hader finds the ring and refuses to return it unless Mindy can prove that it's hers. Meanwhile, Crispo's table accidentally launches food that hits the goths who, in retaliation, declare war. Elsewhere, Mr. Roberts helps Fenwick when his cover is almost blown that he is a seventh grader, but because Fenwick is caught up in all the glory of the eight grade patio, after Mr. Roberts attempts to help him a second time, warning him that if the eighth-graders discover that he is a seventh grader his pants will be taken and hung on the Tree of Pants, he refuses to help him with any future situations. Later, CJ schemes up a plan to get Mindy's ring back, which turns out to be successful and Crispo, who's starving, stops the war and makes peace. Unfortunately for Fenwick, the eighth-graders discover that he is a seventh-grader; however, rather than be humiliated, Fenwick just gives them his pants.

CJ's parents are trapped in highway traffic, Fenwick's parents are trapped at the airport, and Crispo's parents are trapped working late. CJ takes advantage of this dilemma and pretends that she, Fenwick, and Crisp are all trapped on Home Base Station 12, where they have a high chance of being infected with an alien virus. Crispo's brother, Flick, infected with the virus, then shows up, demanding to borrow Crispo's jacket in order to impress girls, but he is denied unless he can say please and is also denied entry to the home base station. Later, CJ, Fenwick, and Crispo are infected with the virus and must create an antidote—a sandwich—and wash their clothes using the virus eradication machine. However, it goes wrong when virus eradication machine goes off balance and the antidote starts burning inside the antidote maker. The power then goes out and Flick continues trying to get in. Fenwick then manages to fix the virus eradication machine while CJ shortly after turns the antidote maker down to medium. Flick manages to get inside after using a ladder to crawl in through CJ's open bedroom window. However, the power is shut off and Flick then steps on soup cans on a step on the stairs and falls down. He finally gives in and says please to Crispo and is also given the antidote in order to neutralize the virus. CJ, Fenwick, and Crispo must then clean up the house from all the messes they made before CJ's parents get home, which they manage to successfully do.

When Blake and his administration are forced to resign after attacking Crispo in a bear costume, CJ, Fenwick, Crispo all run for office. CJ wants to get everyone to have an extra minute with classes and makes a poster. However, while Fenwick and Crispo like the idea, they want their name to be on it instead, so CJ, Fenwick, and Crispo all run for office separately. Mindy and her crew join Crispo's campaign, but Mindy then ends up controlling Crispo's campaign, making Crispo run for office like she would. Later, CJ's mom wants to go negative, but CJ insists on being nice. CJ and her mom bake cookies for the next day so CJ's voice is heard. Unfortunately, this inspires Fenwick to make a negative advertisement commercial about CJ. Eventually, they all end up making multiple negative advertisement commercials about each other before Mr. Roberts intervenes and requests that they stop. They all reluctantly agree to stop, but then Fenwick and Crispo begin arguing the next day during the presidential debate. CJ interrupts to speak out before dropping out of the race in support of Fenwick and Crispo. However, Fenwick and Crispo then do the same, but then all three begin yelling at the audience, talking bad about themselves. Leaving the audience confused, they end up voting for Paul, a student hall monitor. The students at the school end up getting their extra minute, but CJ, Fenwick, and Crispo then realize how long a minute actually is, so they just decide to go to their next class early.

After CJ, Fenwick, and Crispo discover they always lie, they make a vow to always tell the truth. However, when CJ wants to transfer from ceramics class into drama class because of a cute boy, she makes up an emergency lie ticket, in which one lie will be able to be told without consequences. CJ makes up a lie that her grandmother is dying and it's important that she sees CJ perform in a play one last time. Fenwick later uses an emergency lie when he is asked if he made the pot he is holding after having bad luck trying to make his own. Meanwhile, Crispo becomes brutally honest in cooking class when asked to judge the taste of people's cookies. As CJ is rehearsing, she discovers that the cute boy will be her Romeo; however, the boy then reveals that he'd rather be in ceramics class. He is later sent to Mr. Robert's office, who tells him there's a time to tell the truth and there's a time not to and that telling a small white lie is okay every now and then. Later, Fenwick confesses that he lied and then works with the cute boy CJ likes who is good at making pottery. CJ is still keeping up her lie, but later is about to confess when her parents come to the rescue. However, she later realizes that being honest is always important.

When CJ's pootabucks go missing from her super secret hiding place—a 30-year-old unused payphone—she was saving up to go Sir Soaky's Typhoon Splash City Water Park Lagoon, she and her friends must find a way to recover the pootabucks they lost. CJ, Fenwick, and Crispo rush to Mr. Robert's to see if he can help if and he tells them of the legendary treasure chest that belongs to Alfred McSorely and contains one million pootabucks. Principal Hader then interrupts and insists that Mr. Roberts not tell anybody about the treasure chest. Fenwick and Crispo are bent on finding it, but CJ has other plans to try and recover 5,000 pootabucks because she doesn't believe in the legend. Shortly after, CJ runs into Mindy and her group in the hall and discovers she's the one who stole the pootabucks because she was jealous that she couldn't go to the water park. CJ takes the pootabucks box back, but discovers that Mindy used 100 pootabucks and paid their science teacher 50 bucks to have class outside since the air conditioning is broken. CJ begs people and performs various tasks around for more pootabucks, which she's able to obtain. However, she makes a fatal mistake when she hides the pootabucks in another super secret location—the air duct in the science room where the air conditioning isn't working. Not too long after, while having science class outside, a janitor announcements that the air conditioning is fixed and pootabucks start raining from the top of the school. CJ then joins Fenwick and Crispo's search for the treasure chest when they learn there's a clue in Mr. Robert's office. Mr. Roberts gets involved and helps them, but Principal Hader shows up and steals the pootabuck from CJ's hand. However, CJ then realizes that the treasure chest is actually in another spot. CJ, her friends, and Mr. Roberts find the treasure and CJ decides the nice thing to do would be to take everyone to the water park.

The trio look for ways that they will be remembered by the school long after they have moved on. CJ enlists help to save the Gum Wall, an outdoor area where students stick their chewing gum after making a wish, that has been targeted for destruction by Mr. Slinko. Fenwick plans to improve a faulty water fountain known to douse its users. Crispo tries to find a way to get his name on a school plaque; his lack of success attracts other seekers who name themselves the "Shiny Plaque Pack", and Crispo discovers that everyone has an ability that makes them special. Fenwick's efforts destroy the fountain, and the school board replaces it with a properly-working one that is named after him. CJ's efforts transform the wall into a message board where students can ask for help or trade items.

When CJ, Fenwick, and Crispo cannot figure out what their thing is going to be, Mr. Roberts suggests that meeting their idols should be their thing. and they take him up on his suggestion. Crispo wants to meet Olympic snowboarding superstar Louie Vito, Fenwick wants to meet astrophysicist Neil deGrasse Tyson, and CJ wants to meet international pop star Anthony Del Rey. Fenwick asks Mr. Roberts for his help who at first refuses, but then agrees to help him. Mr. Roberts suggests requesting a call or writing a letter, but Fenwick wants to use a shady website that will provide Neil deGrasse Tyson's phone number for $19.95, but Mr. Roberts insists the Fenwick be patient. When Fenwick asks Mr. Roberts how long it took him to wait when he wrote a letter to Neil deGrasse Tyson, he says that it took nine months, and Fenwick freaks out. Meanwhile, Crispo discovers that whoever makes the best commercial for Little Tiny Waffles, Louie Vito will star in the winner's commercial alongside them. Meanwhile, CJ reluctantly becomes a Mindette in order to get a concert ticket to see Anthony Del Rey. Mindy performs a series a tests to see if CJ is a true Mindette, which CJ is prepared for. Later, Crispo is with Fenwick who ended up falling for the shady website's scam and gets the Dominican Republic instead. CJ then passes by with Mindy, leaving Fenwick and Crispo in shock. Meanwhile, when Mindy keeps asking her dad for a bigger limousine, he denies her the tickets after he says she is too demanding. Later, CJ and her mom come up with a plan to meet Anthony Del Rey to stand by the buses when he is leaving the concert. Meanwhile, Crispo is down when his commercial keeps receiving negative comments and wants to make a new commercial. Later, Fenwick hacks Neil deGrasse Tyson's laptop's webcam, but quickly closes Mr. Roberts' laptop when Neil deGrasse Tyson freaks out. Later, CJ runs into Mindy and discovers she stole her dad's wallet to bribe her and CJ's way into the concert. However, instead of participating in that, CJ invites Mindy to come with her and her mom. Later, Fenwick discovers Mr. Roberts is being arrested after Neil deGrasse Tyson called in to report the earlier hack. Crispo walks in and says Little Tiny Waffles rejected his new commercial for being too violent. Just then Neil deGrasse Tyson finally calls, and Fenwick asks for advice on Crispo's behalf on making a good commercial. Crispo then asks Neil deGrasse Tyson if he will help, which he agrees to. Later, CJ, Mindy, and CJ's mom are at the concert waiting to meet Anthony Del Rey when Mindy becomes fan-crazed and tries to get a lock of Anthony Del Rey's hair. As he is retreating back, he falls and breaks his foot. By luck, CJ's dad happened to be his doctor and asked if he could come by and sing a song for CJ. CJ and her mom are surprised to see Anthony Del Rey on the couch when they get home. He then sings her a song, which really impresses her. Later, CJ, Fenwick, Louie Vito, and Neil deGrasse Tyson all help Crispo by participating in another new commercial, which turns out to be a success.

CJ, Fenwick, and Crispo all want to master a thing: CJ does not know what she wants to master and Crispo wants to master "Jingle Bells" on the violin. Fenwick already believes he has mastered a thing—receiving straight As. However, that changes when he receives a B on a Shakespeare assignment and shows that he is the master of tantrums. The teacher calls Mr. Roberts who is all too familiar with Fenwick's tantrums and leads him into his office. Mr. Roberts notices that Fenwick has been a little stressed and asks him about it. After he explains his issues, Mr. Roberts shows Fenwick a pamphlet with relaxation techniques. Meanwhile, CJ ropes her parents into helping her. She discovers there is a kung fu class at the community center and decides to give it a try. When she arrives she notices that Gorgeous Eighth Grade Boy is in the orange division, and that is when she decides that kung fu will be her thing to master. Later, Crispo is having no luck mastering "Jingle Bells" on the violin and gives up. Meanwhile, CJ masters kung fu and makes it into the orange belt division. However, things take a bad turn when she has to fight Gorgeous Eighth Grade Boy. Later, Crispo discovers Tammi Viola, a master violinist, saved his violin from the garbage. She then suggests him to get the rhythm down first. Later, Fenwick is taken into Mr. Roberts' office again, who suggests another relaxation technique. It fails again, but Mr. Roberts discovers that rather than playing dodge ball, he has just been standing there, so he suggests actually participating. Later, after Crispo has given up again, Tammi once again gets his spirits back up by having him listen to what he sounds like among an orchestra. Later during gym, Fenwick discovers that actually participating in sports does reduce stress. Later, after CJ has already discovered that Gorgeous Eighth Grade Boy is terrible at kung fu, she defeats him multiple times. He later comes and CJ sees him with a broken arm, and he asks her to sign his cast. CJ thinks it is her fault, but he says that he actually broke it in a skateboarding accident.

When Crispo receives another bad grade on an assignment, CJ and Fenwick discover it is due to the fact that he refuses to raise his hand out of fear that people will look at him like he's not smart. CJ then makes raising their hand their thing for the day, and Fenwick takes it upon himself to help Crispo. Later, CJ offers to be the tour guide of elementary school students who will be in middle school next year and is looking forward to answering their questions. However, it becomes a challenge when they run away from her and cause trouble. She manages to trap them in the bench of shame room before she loses them again. Mr. Roberts later informs CJ that they ran back to their elementary school and complaint about how CJ was the worst tour guide ever. Meanwhile, Crispo is working on raising his hand in class, finally managing to do it a few times; however, rather than ask for help on the material, he simply asks to use the restroom, breaking his arm the second time he uses that excuse. Meanwhile, Fenwick is a little jealous when Crispo can just raise his hand in the hallway and get a triple high-five from girls. Later, CJ gives touring another shot, but is locked in the lockers by the elementary school students. Fenwick and Crispo come to her rescue after she had called them and the three come up with a plan to catch them. Later, Crispo finally works up the courage to ask an actual question about the material, causing everyone else to raise their hands as well when the teacher notices Crispo's bravery and mentions that answering questions is part of his job. The teacher postpones the quiz that was planned to go over the lesson again. Later, CJ, Fenwick, and Crispo chase and manage to trap the elementary school students in the bench of shame room again, where they admit to CJ that they locked her in the locker out of fear that she was going to do it to them instead and that they're nervous about the middle school experience in general. CJ, Fenwick, and Crispo then give them an official tour of the school and answer their questions. When the tour's over, Mr. Roberts comes over to congratulate CJ, Fenwick, and Crispo on a job well done and sends the elementary school students back to their school. As they're leaving, they each give Fenwick a high-five.

After seeing Ronbie taking his first breakup pretty hard, CJ, Fenwick, and Crispo make it their thing to get their hearts pre-broken in order to survive actual breakups. The plan is to find someone they crush on, ask them out on a smoothie date, and then experience their hearts being broken when they say no. Later, Mr. Roberts is not in the mood to deal with their thing due to parent–teacher conferences. Meanwhile, Crispo asks a girl out on a date in hopes that she will say no, but when she says yes and he then changes his mind, she becomes heartbroken. Fenwick asks Amy, a popular eighth grade girl, out on a date, but she says no because she prefers football players and leaves Fenwick heartbroken. CJ then asks Gorgeous Eighth Grade Boy out on a date and is prepared for the worst, but when he says yes, she is left in shock. Later, after some cheering up from Mr. Roberts, Fenwick attempts to ask Amy out again by bad-mouthing her current boyfriend. She agrees, leaving Fenwick a little surprised. Meanwhile, Crispo attempts to ask another girl out in hopes that she will say no, but when she doesn't, he also makes her cry and is then chased by a mob of angry girls when he reveals he didn't want to go out with any of them, forcing him into Mr. Roberts' office. He then gets the bright idea to make CJ his crush and follows her around all over the place. Amy's boyfriend, Dale, finds Fenwick and chases him. Meanwhile, Crispo gets CJ to say no to a smoothie, but it doesn't hurt him, so continues trying. Dale finds Fenwick and Fenwick discovers that he is heartbroken and just wants Amy back. CJ begins to realize that she and Gorgeous Eighth Grade Boy have nothing in common, especially after he makes her carry his books. Fenwick tries to help Dale win Amy back, when the plan backfires, Dale chases him into Mr. Roberts' office. Later, Crispo reads a poem to a CJ which actually impresses her. Gorgeous Eight Grade Boy's poem, not so much. Fenwick attempts to help Dale again, but when Amy reveals she is going out with someone else, they are both heartbroken and go into Mr. Roberts' office to eat ice-cream, interrupting his meetings yet again. Crispo tries to get his heart broken again, and this time when CJ says no to a smoothie date, he actually feels something that slightly hurts. Crispo then offers to go out with one of the girls he rejected earlier. CJ then gets that same feeling and cancels her date with Gorgeous Eighth Grade Boy. Back at home, Ronbie is back on his feet with a new date and wishes CJ well who is on the couch eating ice-cream.
