Oswaldo goes to a game store and comes across the "Space Ninja Dinosaur". The clerk warns you that the game is extremely dangerous and, once on the Banned Wall, you will never be able to rent anything there again. However, he ends up putting the game in the hands of Tobias, a former gambling addict who is recovering.

Oswaldo and Tobias decide to play lasetag in a joint downtown. Embdate with the fearsome Reaper 3000 - who is actually just a tired old arcade employee - and the rule is clear: one shot and you're "dead", out of the game. When Tobias fails to cover his friend, Oswaldo is hit by the Reaper 3000 and believes he is truly dead. Then he comes home terrified and the fact that he is ignored by everyone - his parents, friends - makes him sure of his ghostly state. For everything he's seen on TV and in the movies, Oswaldo believes he needs to resolve all his issues on Earth to finally cross to the "other side" - issues such as: finishing homework, eating at the school cafeteria for the last time, return a borrowed pen, etc. And to help him, Oswaldo scales Leia and the powerful medium Tobias. Will Oswaldo walk towards the light when the time is right? Or will he realize he's just making a silly drama?

Leia features a videocast about obscure boargames on the internet. She invites Oswaldo to be her assistant during one of the episodes, but he manages to struggle with the pieces and the super glue, making an absurd mess in a few seconds. The video goes viral and he becomes a web celebrity - for a long 3 minutes before the next meme becomes a sensation - the ""boo-yo-yo boy"". But these 3 minutes of fame were enough for Oswaldo to achieve success, hire his father as his agent, write a book and destroy his friendship with Léia - some of the mishaps of fame.... Oswaldo then discovers himself a former famous, a sub-celebrity and the only job he gets is a series of failed events - a pigeon convention, a debutante party and a deadly attempt to viralize a video tape - a new opportunity to regain the glory of the success of hours ago.

The current fashion at school is collecting sticker albums. Oswaldo is trying to complete his ¿card album of the soap opera ¿Corações Bucaneiros¿, the pirates in love. He spends all his money buying stickers and only one is left to complete the album. That's when he discovers one so rare that everyone soon finds out. Everyone wants her. Everyone needs her desperately. Oswaldo then discovers why the sticker is so special: It was made for him to complete ANY sticker album. It breaks the rules of the 4th dimension in such a complex way that it can fry the brain of anyone trying to understand its logic. Angry, right? Just take the card to the classroom where you left the album and it's all right, it's over. Well, nothing is that easy. The special figure caught the attention of Dimitri, the school's mobster. A boy so obsessed with figurines that he became a dark and dangerous being. He used to be Leia's friend a long time ago, when the two dominated the sticker traffic in the area.

Oswaldo is very excited after watching the movie of the year: ¿Moths Weightlifters 7¿. After being exposed to the soda advertisement inserted in the film, he drinks some Maricolas and wins the promotion, he will take the winner to the Amusement Park of Moths Weightlifters (best park!). He, however, runs into a single problem: the ticket guarantees entry for him and a best friend. A. BEST. FRIEND. How to choose between Tobias and Leia? Easy! All you have to do is set up an Oswaldo gameshow, complete with signs from the audience, tricky questions and even a cooking round. All this based on specific knowledge of Oswaldo's tastes. Sounds cool right? But the competition heats up with Leia and Tobias getting more and more crazy to win the game, and more and more competitive with each other, until things get out of hand. Will their friendship survive the crazy stuff of the Oswaldo Game Game show?

The art teacher Jobert takes a vocational test for all the children in the school, that is, a generic test with several questions that determines what profession the children will pursue in the future. Oswaldo takes the test and takes "teacher" as a vocation. Of course, in Oswaldo's mind, this immediately turned him into a trained teacher. He goes to the principal, Marilua, and she, as an educator who believes a lot in “hippies” and unconventional methods of education, believes that it can be an interesting experience for the students. So Oswaldo spends a day teaching his own class, to Leia's displeasure. He recites comics in literature class, covers the blackboard with equations invented in math class, he skips chemistry class because "no one will ever know what chemistry is". Until he notices how sad all his colleagues are. And that's not his fault, it's just that nobody liked the result of the vocational test.

Oswaldo, Leia, Tobias and the guys from the school are at the beach. Oswaldo tries to make his friends believe the day he was able to buy a PF POPS from a beach vendor. What would a PF Popsicle be? Well, I'm glad you asked! The PF Popsicle is a popsicle made with the best ingredients of a dish made: rice, beans, steak, French fries and farofa farofa. Huuummm! Nobody believes in the legend of the PF Popsicle, so Oswaldo sets off on the scorching sand of the beach in search of the Styrofoam that sells PF Popsicles. He's obsessed with proving to his friends that he's not lying. On this journey, he is forced to form an alliance with Medeiros, the rich, spoiled, and quarrelsome boy from high school. He's the only one who believes in Oswaldo. What our penguin doesn't know is that he has other plans for the PF Popsicle. Will Oswaldo find his treasure in the form of a Popsicle? Or will his obsession blind him?

Oswaldo is sad. He was mocked in art class when he presented his artwork "Joinha Duck" (he's a duck, and he pulls a stick!) Depressed, he wanders aimlessly around the school until he hears a very happy song coming from one of the classrooms of class. He is intrigued and discovers something very amazing: it's the nursery room! So Oswaldo decides to join the preschool, where all classes are taught by Furão Listradinho, a Barney-style character on TV. Oswaldo LOVES it: he gets a little gold star for every correct answer, they take a nap every day in the middle of class and he can even wear some super cool shorts that you never need to go to the bathroom again! Kindergarten life is much nicer, he even convinces Tobias to join him in the fun. That is, fun until Oswaldo ran into the wire and accidentally broke the classroom TV. Suddenly all babies turn into drunk zombies, attacking everything they see in front of them, even Tobias was drunk.

It's time to play the Hidden Friend game at school. Oswaldo and Tobias are sure they will take each other out (they've been training). But the training doesn't work and Oswaldo takes out a boy named Alberto, but he doesn't remember anyone with that name. After a brief search, Oswaldo, Tobias and Leia discover who he is. Alberto is a quiet, dull and mysterious boy who sits in the back of the room. Yet Oswaldo is determined to give the best hidden friend gift in the world! So the trio investigates Alberto's life, but finds absolutely nothing. The guy is null. Oswaldo then discovers who he really is: a FIGURANT! He knows those people who are passing by in the background of the scenes that happen in our lives. This means that Oswaldo is the coolest protagonist (of course). And it's up to their megalomania to "promote" Alberto in a supporting role in their gang. What he doesn't know is that Alberto just doesn't like to draw attention.

There's going to be a science fair at the school, and Leia can't wait to win the "Scientist of the Year" award for the project she's been working hard on. The problem is that you can't have Oswaldo and Tobias in the same workgroup. So she decides to help, giving them the classic "beans in cotton" so that she can focus only on her work: a perpetual motion machine. Oswaldo and Tobias manage to make fun of the entire event. They believe they are in a "science fiction fair" and not the normal, boring "Science Fair". Oswaldo Dresses up as a robot and duels with Tobias, who shoots imaginary lasers. They turn the fair into total chaos. It all ends with Leia's experiment being destroyed. She fights with her Oswaldo and Tobias but after seeing them downcast, she decides to fix things.

It's the body swap episode!! Well, more or less. It's family day, an annual tradition in which Oswaldo's mother takes a day off to spend a lovely day with her son. But she uses that day to do everything on her "to-do list": go to the grocery store, take Oswaldo to the dentist, and even call that third cousin who had a birthday. It doesn't seem like much, but she is incredibly happy to have her son with her that day. But can it really? Because Oswaldo REALLY doesn't want to spend the day with his mother doing boring things, so he disguises Tobias as Oswaldo to try to fool his mother. It's not that hard at all. At first she is disappointed with Oswaldo for not wanting to spend time with her, but little by little she decides: it's time for rematch. So the mother starts treating Tobias as if he really were Oswaldo — what's more, she decides to give up her to-do list and take Tobias to the arcade. Oswaldo goes crazy with it, but by then it's too late.

Oswaldo's birthday arrived, uhul!! Only it's Monday, race day and he's super down about it. Well, Leia prepared a surprise for him: she planned a Gamebook around the neighborhood especially for Oswaldo. So, together with Tobias, they walk around town dressed as medieval heroes, and Oswaldo has to follow the script Leia wrote for him, solving questions that will lead him to the lost treasure (it's a surprise party, don't count for him!) But things begin to go wrong when Leia finds out that Tobias decides to rewrite the end of the game without telling her. And as Tobias is a bit of an airhead, they find themselves totally unscripted and in the middle of a perilous journey through the unfamiliar streets of the city. Worst of all, Oswaldo still believes that everything is part of the game.

The day starts like any other in Oswaldo's life. He wakes up, gets dressed and goes to school. Only... there's no one at school!! He is completely alone. Without anyone. At school. Wow!! Of course, Oswaldo decides to mess up everything he can: the chemistry lab explodes, plays with toilet paper and even surfs through the corridors. Until he feels bored being so alone and with no one to talk to. He then gets a Tobias sock and they start talking (well, it's actually him talking to himself) Suddenly the school is completely full of friends made of random things: a broom turns into Leia, the garbage can is Medeiros, a ball with a face is director Marilu, and Oswaldo is living a complete episode of her private show, full of drama, romance, action; all inside your crazy little head. He has a super cool day, but when he gets home he finds it all happened simply because it was Saturday.

Oswaldo, Tobias and Leia are watching Planeta Checho. Leia tries to explain to friends that the program is taped nearby, but the two believe that Checho is really an alien. To try to talk to the presenter, they go to UFO fanatic Gibraltar. After several unsuccessful attempts, they decide to go to the area near the TV recorder's antenna with items that - according to the professor - attract abductions. The three children fall asleep, and wake up inside the studios at Planeta Checho. They spend the show having fun and at the end, Oswaldo and Tobias (who still believe they are on another planet) try to climb onto Checho's "ship".

Oswaldo "kills" the patient in the Operation game who was playing with Leia and Tobias and goes into a crisis. To rethink his life, Oswaldo sets off on a journey around the block. After learning about the stories of Fidel, Rafael, Ernestinho and Maurinha, who encourages him to overcome his trauma of "killing a patient", Oswaldo returns home, but again fails in the game.

Oswaldo wakes up in the classroom at night, with P.A., Sandra, Vivian and Geovan. They think they are there as a punishment for something they did and start talking about it. P.A. wrote a poem on the school desk. Geovan brought a bat to school. Vivian popped all the volleyballs. Sandra tampered with the school's world maps, and Oswaldo put his mouth to the drinking fountain. In the end, everyone enters the Parent-Teacher Meeting to reveal "their crimes" and director Marilua sends them to write an essay about it.

Students are submitting essays about their vacation. Geovan reads his essay, which turns out to be an endless "tic tac", and is interrupted by Professor Gibraltar. In Oswaldo's turn, the bell rings. Oswaldo does not believe that a simple essay is worthy of his vacation, and decides to direct a play about it, paying his colleagues with risolis to act. Finally, his colleagues tire of the impossible stories and the arrogance of Oswaldo, who is forced to admit that his vacation was normal and boring.

Gibraltar sends Oswaldo and Dimitri to work on Stegosaurus. The boys, like a pair of police officers, embark on an adventure in search of the dinosaur book that has disappeared from the school library. Medeiros is accused of stealing the book by Geovan. Dimitri is suspended from school when the book is found in his backpack. Oswaldo, suspicious, unravels the plot revealing that Geovan is the culprit for hiding the book, as it contained information about his love for Leia.

After receiving the grades for a test, Oswaldo, Leia and Tobias lean against the courtyard wall, and are surprised by Ian taking a picture of the three, claiming to be a fan of their band. The three are confused, but end up liking the idea, and decide to create the band. But before they manage to choose the name, Oswaldo remembers what Ozzy said about his experience with Risollica and, paranoid, decides to go solo. On the day of the soiree, Tobias and Leia take the stage, but give up on performing. Afterwards, Oswaldo realizes that it is not worth pursuing a career without his friends, and when they notice that none of them can play, they abandon the career.

Oswaldo goes to work with his father, and quickly becomes bored. They get into a meeting with Colonel Pato, who hates all the ideas of advertisers, until they come across the drawing of Pato Joinha that Oswaldo was making. The Colonel loves the duck, and Oswaldo is immediately hired by the agency, being soon promoted, and ends up firing his own father. But when asked to do a Father's Day campaign, he understands that he shouldn't be doing any of that. He goes out and goes to expopug, to have fun with his friends.

It's a field trip day, and all the students are excited, until they get the news that it won't be Gibraltar who will be the responsible teacher, but Joubert. The children have their candy confiscated, and are divided into three groups to make the artwork. Leia and Oswaldo decide to escape the camp, but are caught during the escape by Medeiros and Joubert, who chase them to the end of the pipe, and only realize that it's an ambush too late. Dawn, and the students leave, forgetting about the two.

Oswaldo is outraged when he learns that his colleagues blocked him on social networks, and during his tantrum, Professor Joubert confiscates the cell phones of everyone in the room, who soon experience an abstinence crisis. Oswaldo then had the idea of creating OSWALDONET. More and more students are interested in the new network, and with all success, Oswaldo decides to earn on top of it, and charges snacks and soft drinks for different services for its users. Tired of the abuse and censorship of the city, Leia organizes a riot, and upon noticing that he has become a tyrant, Oswaldo and his gang go to Joubert to take back their cell phones.

While his mother and father discuss GPS in traffic, Oswaldo gets out of his car to buy water. While looking for a vendor, Oswaldo passes by the car of several colleagues, also stuck in traffic, until he reaches Dimitri's family car - which is broken, and causing a traffic jam. Finally, he meets the water seller, and goes back to his parents' car, passing his classmates' car again.

It's a party day at school, but the focus of the students is the bathroom, occupied by Medeiros, who makes Geovan his hostage. Oswaldo proposes to help, being the rescue negotiator, but even after researching foods that bind and release, he still doesn't understand what might be happening, until he finds out with Leia's help that the problem is a new haircut - and ugly - from Medeiros. Tobias solves the problem with his newest wig made of beards and tufts of hair, and everyone heads off to the party.

All children are in the Trabalhópolis park. Everyone except Oswaldo, who was left out for being too lazy. Revolted by the idea that his colleagues have of him, Oswaldo decides to work, and soon understands the harsh reality of playing at work. Upon discovering what the new park was hiding, Oswaldo tries, with the help of his friends, to reveal the truth about the park. Even in prison, he manages to unmask Trabalhópolis, and the children rebel against the system, reliving the amusement park as it should be, and all go back to playing. Everyone except Oswaldo, who is too lazy to get out of prison.
