It’s garbage day, and a group of the kids collect cardboard and bring it to a young boy named Peter. Peter has been collecting cardboard for a secret project. The group speculates on what the project could possibly be, but Peter refuses to show them. He tells them it’s called Megalopolis and claims that it is coming soon.

As the children play in the street, Roy’s Nanna tries to convince him to join them, but Roy insists that he is too old to play dress-up. Nonetheless, Roy heads outside, but instead of joining the others, he gives them “constructive criticism” about their costumes. A couple of teenagers see this and tell Roy that it was cool of him to help the others with their costumes. They invite him to a costume party they’re having the next day.

The next day, Roy excitedly makes a praying mantis monster costume and heads to the party. However, when he shows up, no one else is in costume, and everyone takes pictures and laughs at him. Roy begins to cry and runs away, tearing off his costume. When he gets home, Roy is furious with his Nanna for pushing him to make friends.
