Chimney Sweep

Chimney Sweep is a recurring endurance challenge where the contestants compete to earn immunity or reward.

Rules
The castaways would brace themselves with their arms between two walls while standing barefoot on two foot pegs. Every 15 minutes, the castaways would move down to smaller foot pegs.
