The boys go on a trip to the water park, where Cartman is distraught to discover that many people from minority groups are in attendance. Cartman calculates there will be no white people left by the year 2012, which he believes is in accordance with the Mayans' prediction of the end of the world. Meanwhile, Kyle is disgusted to learn that most people freely urinate in the pools. The park owner refuses to close and evacuate the park after tests show that its water is 98 percent urine. Consequently overcome by urine tsunamis, the park is quarantined. Rescue operations are delayed until an antidote is found for the "pee contamination" that is believed to have turned the survivors inside into mutants. Cartman finds himself in an inflatable raft where he is the only white person, prompting him to think that the 2012 scenario occurred three years early, and that he is the last of his kind. Kyle, who refused to get into the pee-infested water all day, has to drink urine before he can reach an emergency release valve. However, much to his annoyance, they are rescued immediately afterward.
