S11, E2: Sibling thresholds are about to be seriously tested in the warped world-premiere episode of Camp Orange Twisted Siblings! We meet the four pairs of siblings who proved to be crazy enough to take on the slimiest, smelliest and sickest challenges in the show’s history. In the first major twist of the series, we also learn that Nickelodeon’s Jack Griffo and Kira Kosarin (who play troublesome superhero twins on The Thundermans) will be hosting the show. The biggest revelation of the episode – the teams find out that they will be competing to be crowned Nickelodeon’s Star Siblings, becoming the official stars of Nickelodeon for 2015!
