Buggin' Out

Survivor Smorgasbord (popularly known as the "Gross-Food Eating Challenge") is a recurring challenge that originated in and was used in later seasons.

Rules
In this challenge, castaways must eat a variety of native, (usually gross) foods. This challenge has appeared multiple times throughout the Survivor series.

As a tribal challenge, whoever finishes the dish first, wins a point for their respective tribe. When this challenge is used as an individual challenge, the last person to finish each dish is out, the last player remaining wins.

History
In its debut during  in, where the survivors were to eat a serving of butok or bug larvae. If a contestant refused to eat the beetle larvae, the contestant's tribe would automatically lose the challenge for the tribe. In order to break the tie, each tribes' most squeamish member faced off. Gervase Peterson and Stacey Stillman were pitted against each other. Stacey finished the larva first and won for Tagi.

The challenge returned in the episode, where a person from each tribe would compete against someone from the other. A spinning wheel determined what was to be eaten. This time, if someone refused to eat or threw up, they would lose a point for their tribe. Again, the challenge ended in a tie. Kimmi Kappenberg and Tina Wesson were chosen for the tiebreaker, and Kimmi won for Kucha by eating a mangrove worm first.

Another variation of this challenge appeared in the episode  where castaways had to drink a shot of cow's blood. During the early rounds of the challenge, milk was added to the blood to make it more appetizing. This challenge ended in a tie, in which Kelly Goldsmith and Linda Spencer had to drink a full glass of pure cow blood. Linda finished first and won for Samburu.

The challenge again appeared in. Tribe members had to eat farfaru (sunbathed fermented fish). This challenge ended in a tie, so Rob Mariano and Neleh Dennis had to compete against each other in the tiebreaker. Rob threw some of it up, while Neleh finished first and won for Rotu.

The first time that it was used in the post-merge phrase was in, it was used as the Loved Ones Challenge. The last loved one standing won, Helen Glover's husband Jim won over Jake Billingsley's wife Jenny. At the final four Immunity Challenge, its final round was a tarantula-eating contest. Eventual season winner Brian Heidik won the challenge.

The challenge was reused in as an individual Reward Challenge, where the reward was a pizza feast with the winner's loved one to be enjoyed at the old Chapera camp. Similar to Thailand, the loved ones competed for reward. The slowest to finish a dish each round was eliminated. Tom Buchanan's son Bo won this challenge over Rob Mariano's brother Mike.
