THE TRIBES HERD PIGLETS AT THE REWARD CHALLENGE, ON "SURVIVOR: VANUATU�ISLANDS OF FIRE," THURSDAY, OCT. 21, ON CBS

"Hog Tied" -- The tribes attempt to herd piglets at the Reward Challenge, on SURVIVOR: VANUATU -- ISLANDS OF FIRE, Thursday, Oct. 21 (8:00-9:00 PM, ET/PT), on the CBS Television Network.

A piglet-herding competition offers a feast for the winning tribe, but one tribe's chance of victory might be hurt by one person's fear of pigs. One castaway feels very vulnerable and gives an impassioned, persuasive speech with the hopes of breaking the tribe's existing alliances. Things are very relaxed at one camp�so much so that one castaway decides to do some nude sunbathing. Additionally, a walk to gather food forges a growing alliance. At Tribal Council, one castaway prays for a sign to guide the decision of their vote and, sure enough, a sign appears.

And, the seventh member is voted out of the tribe.
