The narrator, Robinho, observes Beto having a party with blue balloons at his house. Robinho, wearing green, decides to join the party, despite not being invited, to show off his cooler green balloons. Beto answers the door and initially doesn't want Robinho to join, but eventually lets him in.
As Robinho enters, he notices that Beto is alone and that the party seems to be just for himself. Robinho suggests they make the party more lively and decides to burst the balloons. Beto objects, but Robinho persists.
Instead of bursting the balloons, Robinho suggests they tie them to themselves and their clothes, which causes them to float. They start to have fun, but then Robinho proposes a new idea - to tie the balloons to their arms and legs to make themselves fly. Beto is hesitant but eventually agrees.
They float around the house, and Robinho suggests they add more balloons to fly higher. However, Beto becomes concerned about losing control and falling. Robinho reassures him that he will be okay.
As they continue to float, they start to feel dizzy and disoriented. Suddenly, they find themselves in a strange, dark place with monsters, including zombies and bats. Robinho and Beto try to defend themselves, but they're not sure how they got there or how to get back home.
They explore the dark place, finding hidden doors, corridors, and pressure plates that trigger traps. Along the way, they encounter various monsters, including a strange creature without arms and a pig. They also discover a secret hideout with multiple doors.
As they navigate the hideout, they encounter Herobrine, a ghostly figure who is the scariest monster in the world. Robinho and Beto try to defeat Herobrine, but he disappears suddenly.
After Herobrine's disappearance, Robinho and Beto search for a way out of the dark place. They use balloons and blocks to navigate the environment and eventually find a way out. However, in the process, Robinho accidentally leaves Beto behind, and Beto has to find another way out.
In the end, Robinho and Beto reunite, and it appears that Herobrine has died. They also manage to finish off the monster that lives in the hole of illusion.
