The series is a reality show parody where twenty-four cartoon characters settle at Camp Wawanakwa, a fictional island located in an unspecified area in Muskoka, Ontario. Every three days, the campers must participate in the challenge which normally has at least one winner for their team that met the qualifications of the challenge and gave their team invincibility. The losing team (up until the point where the teams are disbanded) is called to the campfire at night, where Chris McLean (the host) passes out marshmallows. Those who receive a marshmallow get to stay, while the one who does not get a marshmallow has been voted off the island, and must walk down the Dock of Shame to the Boat of Losers, which will take them away and they will "never, never, never, ever, ever, ever, come back, ever" (according to Chris). About halfway through the competition, the teams are disbanded, which means (as Chris puts it) "every camper for themselves," and the winner of the challenge only gets invincibility for him- or herself. This process of elimination continues on until one player remains on the island. At the end of the series, the last contestant will win C$100,000 (US$93,761.68).
