The eighteen All-Stars arrived at Panama already divided into three tribes, Chapera, Mogo Mogo and Saboga. They were only given water canteens to start, and received no information and no fire. The three tribes received maps to their respective camps. When Chapera made it to their camp, they found a well with contaminated water. The tribe decided to focus on building their shelter. Over at Mogo Mogo, the tribe members were scrambling to create alliances. Eventually, they agreed that no one trusted each other, and that they would focus on their camp before alliances. Chapera and Saboga desperately needed fire. At Chapera, Alicia and Boston Rob were fighting over whether to focus on fire or shelter. After the fight, Boston Rob formed an alliance with Amber, while Rudy and Rupert formed an alliance at Saboga.
