Barrel of Monkeys (also known as In The Barrel) is a recurring challenge on Survivor.
One or two castaways are placed inside a barrel and are pushed throughout a course by their tribe mates, collecting items along the way. The first tribe to finish the course wins.
In Blood vs. Water, Galang and Tadhana were neck and neck the entire race, but when it came to the final leg where a member of each tribe had to play skee ball, Gervase Peterson was able to finish his task before Hayden Moss, claiming victory for his tribe and sending Tadhana back to Tribal Council.
The challenge reappeared in Cambodia as a Reward Challenge. Despite Bayon falling behind on the barrel rolling portion, they managed to regain some time in the ball rolling portion. They were, however unable to make a comeback as Ta Keo finished first and Angkor finished second.
