The tribes received Tree Mail along with body paints of five different colors. The tribe members were instructed to paint themselves with one color representing each member. When the tribes met Jeff, he explained that they would be having a "get-to-know-you". The castaways were instructed to pair off with the person wearing the same paint color. The pairs chose baskets at random. The pair of Clay and Shii Ann received a note telling them to travel to the Chuay Gahn camp. The pair of Ken and Helen were instructed to travel to the Sook Jai camp. The four were instructed to choose which camp would be more comfortable to live in. They chose the Chuay Gahn camp, and Jeff explained that everyone would be living at that camp. Believing the tribes had merged, the castaways created a new name, Chuay Jai by mixing the two tribe names. When they returned to camp, a feast was waiting for them. Later on, Shii Ann, who was on the outside of the Sook Jai tribe, talked to Ted about flipping to Chuay Gahn. Ted agreed to let Shii Ann into their voting block. Later on, Brian asked Shii Ann to flip to Chuay Gahn to vote out Penny. As the castaways gathered for an individual immunity challenge, Jeff shocked the castaways by explaining that the tribes hadn't actually merged, but were simply living on one beach.
