However, they soon realize that to progress further, they need to spend real money on in-game currency.

As the boys continue to play, they become increasingly frustrated with the limitations imposed by the game's freemium model. Stan, who is particularly annoyed, expresses his disdain for the way the game is designed to manipulate players into spending money. Meanwhile, Cartman, who is more willing to spend money, begins to buy in-game currency, which leads to tension among the group as they debate the ethics of spending money on a free game.

The scene shifts to the boys at school, where they discuss their experiences with the game. Stan is adamant about not spending any money, while Cartman boasts about his purchases and the advantages they give him in the game.

In a pivotal moment, Stan proposes that they should create a protest against the game and its freemium model. The boys rally together, and they start to spread the word about their protest, encouraging other kids in South Park to join them. They create posters and plan a demonstration outside the local game store, hoping to raise awareness about the negative impact of in-app purchases on gaming.

As the protest day arrives, the boys are excited but also nervous. They gather with other kids outside the game store, holding signs and chanting slogans against the freemium model.

Meanwhile, Cartman, who has been secretly enjoying the benefits of his in-game purchases, begins to feel conflicted about the protest. He realizes that he is enjoying the game more than he wants to admit, and he struggles with his loyalty to his friends versus his desire to continue playing. This internal conflict leads him to make a decision that will impact the group.

In a surprising twist, Cartman decides to sabotage the protest by using his in-game currency to create a fake version of the game that is even more exploitative.
