The tribes will race through an obstacle course with their carts. They must climb various ladders, retrieving keys. Those keys unlock a chest containing puzzle pieces. They must then put the chest on their cart and make their way through the obstacle course to a wall. When they get to the wall, they must disassemble the cart. They must then pass the cart and the chest through the wall. After reassembling the cart, they must make it to the end, where two players will assemble the puzzle.
In Cagayan, the challenge appeared as the first Immunity Challenge of the season. Luzon immediately struggled, while Solana and Aparri were both able to pull ahead and finish, sending Luzon to Tribal Council.
