This article is about the challenge. For the episode of the same name, see "Sumo at Sea".

Sumo at Sea (also known as Kung Fu Cannibals and Sumo in Mud) is a recurring challenge that originated in Survivor: Palau and was used in later seasons.


One member from each tribe faces off on a platform surrounded by either water (Palau, Blood vs. Water, and San Juan del Sur) or mud (Fiji and Heroes vs. Villains). Using their padded bags, or any other body part other than their hands, they must try to knock each other off the platform. Doing so would score their tribe a point. The first tribe to reach a certain number of points would win.


In Survivor: Palau, its debut season, Koror narrowly managed to beat out Ulong for immunity.

The challenge reappeared as a Reward Challenge in Survivor: Fiji. Moto won, taking home fishing gear, toiletries, coffee, and potatoes.

The Heroes won this challenge in Survivor: Heroes vs. Villains in a blowout. In addition to immunity, the tribe also won rice, sugar, coffee, and the tribe's luxury items.

The challenge appeared once again in Survivor: Blood vs. Water. Although Tadhana started off strong, Galang managed to make a comeback and ended up winning their third Immunity Challenge.

The challenge appeared again in Survivor: San Juan del Sur as the second Immunity Challenge. The two tribes were very evenly matched, and Kelley Wentworth avenged her loss to Jaclyn Schultz in the first round by defeating her in the final round, securing immunity for Hunahpu for the second straight time.
