In, the tribes start at opposite ends of the playing field with three canvas bags. The tribes have to battle their way to their end zone. The tribe that has their three bags and two of the other tribe's bags in their end zone at the same time wins.

History
The challenge debuted in as the episode three Reward Challenge. Two contestants from each tribe would swim out to retrieve an inner tube and try to bring it back to their tribe's platform while contestants from the other tribe would try to stop them. The first tribe to three points won. Ulong won this challenge in a 3-0 sweep over Koror.

The challenge re-appeared in as a tribal Immunity Challenge. The first tribe to score three bags won the challenge. Casaya narrowly defeated La Mina 3-2 to win immunity.

In, playing in an area similar to a football field, the tribes start at opposite ends of the playing field with three canvas bags. The tribes have to battle their way to their end zone. The challenge ends when one tribe has their three bags and two of the other tribe's bags in their end zone at the same time. The tribes, dressed in war paint, had a very physical battle in the rain with the reward of items chosen from a catalog. Malakal won the challenge over Airai, taking home a tarp, a lighting kit, and a survival kit.
