The castaways play for fishing gear in the "Do or Dive" reward challenge, in which members from each team must dive beneath the water and take heavy stones from a sunken boat. The first team to get their boat afloat and to land wins. For immunity, each tribe member must eat a smelly Marquesan delicacy called fafaru that consists of raw fish, fish bones, crab legs and lobster legs marinated in sea water and left in the sun for three days. The second person is voted off of the island.
