In the episode, Eric Cartman inherits a million dollars from his deceased grandmother and uses it to purchase his own amusement park, which he names Cartmanland.
Cartman tries to hire a security guard for the park after what happened, but the man he chooses insists on receiving a salary instead of being paid in free rides.
Expenses for ride maintenance, refreshments, utilities, and added security begin to mount over the next few days, forcing Cartman to sell more and more tickets to cover them.
As a crowd gathers to watch Cartman's misery, Kyle's hemorrhoid subsides and he almost instantly recovers, now with both his faith in God and will to live renewed.
In the DVD commentary for the episode, Parker and Stone highlight it as another example (after "Scott Tenorman Must Die") of the show's change in style towards simpler ideas which consist only of an A-Plot, with no subplot, and "not try[ing] to do too many things at once."
[2] The security guard whom Cartman hires, and who uses pepper spray, was previously the lead mall cop in the season four episode "Something You Can Do with Your Finger".
He is also featured in the 2014 South Park video game The Stick of Truth as the first boss, guarding Tolkien Black's mansion and using his pepper spray on the player character unless they wear a gas mask.
"Cartmanland," along with the thirteen other episodes from South Park: the Complete Fifth Season, was released on a three-disc DVD set on February 22, 2005.
