In "Summer Sucks", the boys are excited for summer and intend to buy fireworks. However, they are denied when they quickly find out that fireworks have been outlawed. They learn this is so because a child from North Park was severely injured in a fireworks accident.
In "Sarcastaball", the boys, and the rest of their Sarcastaball team, play a game of Sarcastaball against a similar team from North Park. Before the game, Butters Stotch gives an inspirational speech, which motivates the South Park team to be "nicer" than the North Park team.
- There is a basin called North Park in Colorado, but it is not a town.
